The ILD detector concept has originally been developed for the Inter-
national Linear Collider (ILC). Detailed simulations gauged against
the performance of prototype components have shown that ILD in its
ILC incarnation is ideally suited to pursue the physics program of a
linear Higgs factory as well as of a higher energy 𝑒+𝑒− collider. Re-
cently, the ILD collaboration has started to...
The CMS experiment will be upgrading its detectors in lieu of higher lu-
minosities and collision rates during the High-Luminosity era of the LHC (HL-
LHC). One key upgrade of the CMS detector will be its end-cap calorimeters,
which will be fitted with the new High Granularity Calorimeter (HGCAL).
Since the HL-LHC will have 10 times more luminosity, the HGCAL will have
improved radiation...
Strong-Field Quantum Electrodynamics (SFQED) is an emergent field
of physics, where conventional quantum electrodynamics calculations
become non-perturbative due to a strong electromagnetic background
field. This gives rise to non-linear Compton scattering and non-linear
Breit-Wheeler pair production. Advances in laser technology have
made it possible to explore this field, by colliding...
The DESY II Test Beam Facility offers electrons with a user se-
lectable momentum from 1-6 GeV primarily for detector characterisa-
tion. TelePix2, a HV-CMOS sensor, is the latest new user infrastruc-
ture at the test beam facility used as an arbitrary Region of Interest
(ROI) trigger and a timing plane, for efficient small prototype testing
and ambiguity suppression.
This contribution...
Electron-bunch-driven plasma-wakefield accelerators promise to revolutionize particle acceleration by
providing compact and cost-effective energy boosters for electron linacs which could, for example,
significantly enhance the photon energies produced by free-electron lasers. The FLASHForward facility at
DESY has made substantial progress, demonstrating that accelerated electron bunches can...
Measuring the Higgs self-coupling represents a cornerstone of the
physics program of future colliders because it gives important insights
into the shape of the Higgs potential. This contribution summa-
rizes the updated projections for the determination of the Higgs self-
coupling from di-Higgs production at future 𝑒+𝑒− colliders. In partic-
ular, we will present an update of the analysis...
High Luminosity era of the LHC is fast approaching and the upgrades of the detector systems are now in various stages of production. The CMS experiment will receive a High Granularity Calorimeter (HGCAL) to replace the existing endcaps. Active layers of the upcoming sampling calorimeter are being constructed, and, I bring into focus work performed in the Tile Assembly Center in DESY on...
Plasma-wakefield acceleration (PWFA) promises to reduce the size of future machines significantly by providing multi-GeV/m acceleration gradients, orders of magnitude higher than conventional RF accelerators. However, PWFA is a process with many non-linear dependencies, making it difficult to understand the influence of input parameters. Moreover, measurements of e.g. energy spectra are...
