Description
The Helmholtz Initiative for Accelerator Research & Development (ARD) was established to strengthen development in accelerator physics and technology and to ensure international competitiveness. In this framework, accelerator scientists push the limits of today’s technology in a research network of six Helmholtz centers (Deutsches Elektronen-Synchrotron (DESY) in Hamburg and Zeuthen, Helmholtz Zentrum Dresden-Rossendorf (HZDR), Forschungszentrum Jülich (FZJ), Helmholtz Zentrum for Heavy Ion Research GSI in Darmstadt, Karlsruhe Insitute for Technology (KIT), and Helmholtz Zentrum Berlin for Materials and Energy (HZB) ), two Helmholtz institutes, eleven universities, two Max-Planck institutes, and the Max-Born institute. The sixth ARD topical workshop on “ps - fs Electron and Photon Beams” will focus on three fundamental areas of current research in the field of short pulse particle accelerators, namely research related to synchronization and seeding, ultra-fast pulse diagnostics, and photon radiation and interaction. The workshop aims to bring to together scientists from universities and Helmholtz centers that are involved in the subtopic 3 (ST3) “ps – fs Electron and Photon Beams” of the ARD program. It shall serve to further strengthen collaborative projects at and between the different accelerator facilities. The workshop shall also serve to educate young researchers and students participating in projects and experiments within ST3.

        First design studies on a NC CW RF gun for European XFEL 1h 30m
        High brightness high-repetition rate (MHz-class) electron source for European free-electron lasers (FELs) upgrade program is under design at the Photo Injector Test facility at DESY, Zeuthen site (PITZ). A normal-conducting (NC) cavity resonating in the VHF band at 216.7 MHz operating in continuous wave (cw) mode is chosen as the backup candidate. The preliminary design studies of the NC cw RF gun was carried out. The cathode gradient and voltage were pushed to 30 MV/m and 860 kV to improve the beam brightness. This poster presents the RF design and optimization of the copper cavity, multipacting simulation, beam dynamics study as well as the mechanical thermal and stress analysis.

        Influence of the chirped electron beam on THz radiation. 1h 30m
        As is well known, coherent emission of radiation from ultrarelativistic electron bunches takes place when the duration of the bunches is shorter than the radiation wavelength. In this case, the contributions to the field from all electrons sum up in phase, and the output intensity scales as the square number of electrons in the bunch. In this work, we consider the particular case of coherent emission of radiation from an undulator in THz range. It is often the case that the electron bunch at the entrance of a THz undulator setup, for accelerator-based THz sources, has an energy chirp. We investigate the influence of the energy chirp of an electron bunch on coherent radiation.

        Influences of Impedances on Longitudinal Beam Dynamics 1h 30m
        The beam dynamics in a particle accelerator are influenced by its impedances. In particular at high charge densities, the production of coherent synchrotron radiation is governed by the longitudinal impedance. With Inovesa, an in-house developed simulation tool, it is possible to simulate the dynamics of the longitudinal phase space density inside a storage ring by solving the Vlasov-Fokker-Planck equation. A complex example for an impedance induced effect is the micro-bunching instability, driven by the CSR self- interaction. In general, a precise knowledge of real world impedances and their implications is required. In this contribution, we present systematic studies of the effects of various simplified impedances on the observed longitudinal phase space density.

        Studies of Longitudinal Dynamics in the Micro-Bunching Instability using Machine Learning 1h 30m
        The operation of synchrotron light sources with short electron bunches increases the emitted coherent synchrotron radiation (CSR) power in the THz frequency range. However, the spatial compression leads to complex longitudinal dynamics, causing the formation of micro-structures in the longitudinal bunch profiles. The fast temporal variation and small scale of these micro-structures put challenging demands on their observation. At the KIT storage ring KARA (KArlsruhe Research Accelerator), diagnostics have been developed allowing direct observation of the dynamics by an electro-optical setup, and indirect observation by measuring the fluctuation of the emitted CSR. Additionally, the longitudinal dynamics can be simulated using the numerical Vlasov-Fokker-Planck solver Inovesa. In this contribution, we present studies of the micro-structure dynamics on simulated data. To deal with generated data sets in the order of terabytes in size, we apply the machine learning technique k-means to identify the dominant micro-structures in the longitudinal bunch profiles. Following this approach, new insights on the correlation of the CSR power fluctuation to the underlying longitudinal dynamics can be gained.

        Studies of the Micro-Bunching Instability in the Presence of a Damping Wiggler 1h 30m
        At the KIT storage ring KARA (KArlsruhe Research Accelerator), the momentum compaction factor can be reduced leading to natural bunch lengths in the ps range. Due to the high degree of longitudinal compression, the micro-bunching instability arises. During this longitudinal instability, the bunches emit bursts of intense coherent synchrotron radiation in the THz frequency range caused by the complex longitudinal dynamics. The temporal pattern of the emitted bursts depends on given machine parameters, like momentum compaction factor, acceleration voltage, and damping time. In this contribution, the influence of the damping time is studied by utilizing the CLIC damping wiggler prototype installed in KARA as well as by simulations using the Flasov-Fokker-Planck solver Inovesa.

        Study of a Superconducting Transverse Gradient Undulator for a Laser Plasma Accelerator-Driven FEL 1h 30m
        The application of Laser Wakefield Accelerators (LWFA) is a potential key for realizing extremely compact Free Electron Lasers (FEL) due to an unprecedented high longitudinal electric field inside the laser-driven plasma wave. LWFA-based electron beams exhibit challenging initial conditions in terms of beam divergence and large energy spread. The superconducting transverse gradient undulator (TGU) scheme is a viable option to compensate the challenging properties of the LWFA electron beam to enable FEL amplification. A first test of the TGU was performed in a specially designed cryostat of KIT at liquid helium temperature (4.2 K). The first TGU cooling process to 4.2 K was successful. A preliminary magnet powering test was performed by using one of the two undulator coil. The results of these tests are presented in this contribution.

        THz afterburner undulator for selective THz control experiments at the European XFEL 1h 30m
        Different options for proving intense THz filed for THz pump - X-ray probe experiments at the European XFEL using laser-based and/or accelerator-based techniques are currently discussed. Here we present a concept which is based on a superconducting THz undulator utilizing the spent electron beam of the eV scale linac as an afterburner to produce narrowband, tunable, few-cycle THz pulses with world-record intensities. A challenge to this approach is the very high electron beam energy of up to 17.5 GeV which yield particular requirements for the specific undulator design. In this presentation, we will report the preliminary study of the undulator design for the European XFEL and present the radiation properties including expected pulse energies, spectra, and temporal profiles.

In this presentation, we will report some preliminary results for boosting THz pulse energies assuming specific ideal model bunch forms for the case of the TELBE facility and an envisioned future THz afterburner undulator at the European XFEL.

        Application of MicroTCA.4 for Diagnostics at the European XFEL and at FLASH 1h 30m
        The accelerators of FLASH and of the European XFEL deliver electron bunches in bursts of several hundred pulses with MHz repetition rates every 100ms. These bunches are distributed between different undulator beamlines to generate FEL pulses with few to hundred femtoseconds temporal width in the soft to hard x-ray regime. To run these high repetition rate FELs a large number of different fast detectors and diagnostics, regulation and feedback systems are required which are to a large extent read out or directly controlled by MTCA.4 hardware. This poster gives a few examples of the different MTCA-related applications implemented at both facilities.

        Development of a Silicon Strip Detector for the ARES Spectrometer. 1h 30m
        In collaboration between DESY MPY-1 and DESY FH ATLAS a silicon strip detector for the ARES spectrometer is being developed. This detector will be used for low (sub-pC) charged beams where a good spatial resolution is needed. It will be placed after the spectrometer dipole. The detector consists of two 1cm x 1cm silicon strip sensors. The readout is done by 4 charge-to-digital converters with three strips grouped together per readout channel. The key specifications of the ATLAS miniatures strip sensors developed for the HL-LH ATLAS tracker upgrade are a pitch of 74.5 micron, 103 strips per sensor and a thickness of 310 microns. Current-Voltage and Capacitance-voltage measurements were performed at the UNI HH lab. Measurement results and a dedicated charge production simulation tool will be presented and discussed in detail. A proof of principle experiment is foreseen at the DESY II test beam at the beginning of 2019.

        Longitudinal electron bunch diagnostics for LWFA based on broadband, spectral CTR measurements at single-shot 1h 30m
        Laser-wakefield accelerators (LWFA) feature electron bunch durations on a scale of a few fs. Precise knowledge of the longitudinal profile of such ultra-short electron bunches is essential for the design of future table-top X-ray light sources. The resolution limit, as well as the limited reproducibility of electron bunches, pose big challenges for LWFA beam diagnostics. Spectral measurements of broadband transition radiation from LWFA electron bunches passing through a metal foil are especially promising for analyzing ultrashort longitudinal bunch characteristics ranging from of tens of fs down to sub-fs. Our broadband, single-shot spectrometer combines the TR spectrum in UV/VIS (200-1000nm), NIR (0.9-1.7μm) and mid-IR (1.6-12μm). A complete characterization and calibration of the spectrometer has been done with regard to wavelengths, relative spectral sensitivities and absolute photometric sensitivity. Our spectrometer is able to characterize electron bunches with charges as low as 1 pC and resolve time-scales from 0.4 to 40 fs. We present results from recent measurement campaign by analyzing transition radiation spectra produced by nC class LWFA electron bunches using ionization-injection, while complementary data on the transverse bunch profile is provided by simultaneously imaging the CTR in the far- and near-field. We discuss the data analysis from detection to profile reconstruction with error analysis and show electron bunch profiles as determined from experimental density scan measurements.

We have developed KALYPSO, a line array detector with 1024 pixels operating at 10 Mfps. To improve the spatial resolution and sensitivity at different wavelengths, novel Si microstrip sensors have been developed with a pitch of 25 μm. Furthermore, to enable measurements of the beam profile with a repetition time of 2 ns, a sensor based on Low Gain Avalanche Detector (LGAD) coupled with a SiGe readout is under development. The detector system and the characterization of the sensors will be presented.

        A new approach to femtosecond level intrinsic synchronization between accelerators and external laser systems 1h 30m
        The timing jitter between accelerator-based light sources and external laser systems is nowadays the critical limit for the achievable temporal resolution in ultrafast time-resolved experiments at 4th generation light sources such as superradiant terahertz (TELBE) facilities or X-FEL's. In this work we demonstrate the proof-of-principle experiment. It was experimentally shown that our scheme allow us to compress timing jitter between two laser systems by 2 orders of magnitude, from 2ps to 15fs by utilizing laser induced single cycle THz pulses as gate signal based on electro-optic slicing.

        CONTROL SYSTEM DESIGN FOR SRF CAVITY BASED ON KALMAN FILTER OBSERVER 1h 30m
        Superconducting Radiofrequency Cavities as planned for BESSY-VSR or bERLinPro require a high stable RF field of the accelerating mode in order to allow as for VSR a stable RF beating scheme. Further, to ensure efficient operation at low RF power consumption, these type of cavities are operated at low coupling, i.e. narrow RF bandwidth. Hence, any disturbance to the system by unwanted cavity detuning can finally lead to the worst situation of a beam loss. The modern SRF cavity control system should take into consideration not perfect model of microphonic disturbances, sensor noise and model instabilities as well as the limitation for the number of expensive sensors. To cope with such class of systems the general approach is based on using linear quadratic regulator together with an observer. The optimal observer based on so called Kalman Filter (KF) was tested nowadays as the data processing firmware in a real mTCA equipment. The input is provided by the virtual cavity representing software/hardware debugging complex and the real-time KF response is then examined. The test results shows relatively good correlation between predictable behavior and KF output.

The cavity, waveguide and klystron signals will be down-converted from 12 GHz to 3 GHz and further processed in a standard 3 GHz S-Band RF control system based on MicroTCA.4. In this poster, we will present the 9 GHz LO generation method and measurements of the 12 GHz front-end prototype setup. Preliminary results have shown a short-term jitter of about 1.1 fs rms for the LO generation and 1.1 fs rms resolution for the X-Band down-conversion. Further steps concern the PCB integration as well as the discussion of the 19“ chassis packaging.
