Latest results using interferometry at ALBA

• Ubaldo Iriso (ALBA-CELLS)

Room: Seminar Room 1 This presentation shows the latest results obtained using the visible light interferometry at ALBA. On one side, we describe how the transverse beam shape can be reconstructed and detect beam tilts; and secondly, we present the first (qualitative) measurements of the bunch-by-bunch beam size.

New Bunch-by-Bunch feedback at Diamond

• Günther Rehm (Diamond Light Source)

Room: Seminar Room 1 Diamond is currently building a longitudinal bunch-by-bunch feedback. The electronics for that are based on COTS parts in uTCA, providing 500MS/s 14bit ADC and DAC, Virtex7 FPGA and 4 core Xeon Processor. We report on where we are on the project.

New trends in beam diagnostics - Zynq XX based instruments

• Peter Leban (I-Tech)

Room: Seminar Room 1 There is a population of instruments built around Zynq7020 covering several applications: beam position (storage ring, linear), photon beam position, beam loss monitoring and as simple as digitizer. Laboratories, such as INFN, SPring-8 and PAL require higher sampling rates, more flexibility in the analog front-end and wider choice of connectivity (e.g. optical). The next generation of Zynq XX based instruments might be built as independent digital and analog front-end while retaining the software infrastructure that supports EPICS, TANGO and other clients out of the box. Possible candidates are the cavity BPM electronics and multi-channel digitizer, both with 250 MHz to 500 MHz sampling rates and optional exchangeable analog front end.

Modulating RF phase at twice synchrotron frequency

• Günther Rehm (Diamond Light Source)

Room: Seminar Room 1 By modulating the cavity RF phase at twice synchrotron frequency, bunches can be lengthen and shortened. We have done this both in normal optics (17ps bunch length) and in low-alpha optics (3ps bunch length). The effects can be nicely observed on the streak camera.

ALBA BLM studies and historical analysis

• Andriy Nosych (ALBA-CELLS)

Room: Seminar Room 1 During 5 years of operation in the 3 GeV storage ring of ALBA, the 124 beam loss monitors have provided measurements of relative losses around the machine, with around 10% of breakdown units. We analyzed these failures and correlate the integrated received dose with any special conditions of each BLM location which might have led to their breakdown. We also show studies of beam losses in the insertion devices, with particular attention to the results in the MPW, where the vacuum chamber is (suspected to be) misaligned and high BLMs counts are detected.

Status of the Solaris 1.5 GeV Storage Ring

• Arkadiusz Kisiel (Solaris)

Room: Seminar Room 1 The Solaris is a third generation light source constructed in Poland consisting of a 600 MeV linear injector and 1.5 GeV storage ring. The layout of the storage ring is based on a novel Double Bend Achromat (DBA) magnets designed in MAX-IV Laboratory in Sweden. During the commissioning phase of the Solaris storage ring the performance of this innovative concept has been succesfully verified and obtained parameters allowed to start the commissioning of the first beamline. The beam diagnostics and instrumentation system is beased mostly on 36 quarter-wave button BPMs spreaded along the ring what allowed to measure and monitor several beam parameters like closed orbit, tune, chromaticity, disperssion, orbit response durin the commissioning and operation phases. The results of the the latest machine optimization including the orbit correction, linear optics measurements and beam-based alignment will be presented.

Refurbishment of the screen diagnostic system at ANKA

• Marcel Schuh (KIT)

Room: Seminar Room 1 The screen diagnostic presently is based on analog cameras and direct displaying the image on TV screen using a video switch. It is planned to replace this system by a system based on digital Cameras and central image processing. The concept and the given constrains will be discussed.

Performance studies of CCD cameras based on signal-to-noise and photon transfer measurements

• Gero Kube (DESY)

Room: Seminar Room 1 Taking advantage of the rapid development and the huge market for commercial available optical sensors, in the past years optical measuring techniques took on greater significance. Nowadays, area scan CCD or CMOS sensors are widely used for beam profile diagnostics. They provide the full two-dimensional information about the particle beam distribution, allowing in principle to investigate shot-to-shot profile fluctuations at moderate repetition rates. In order to study the performance and to characterize these cameras, photon transfer is a widely applied popular and valuable testing methodology. In this contribution, performance studies based on signal-to-noise and photon transfer measurements are presented for CCD cameras which are in use for beam profile diagnostics at different DESY accelerators.
