The PSI positron production project
/ Vallis, Nicolas (PSI, Villigen ; Ecole Polytechnique, Lausanne) ; Craievich, Paolo (PSI, Villigen) ; Schaer, Mattia (PSI, Villigen) ; Zennaro, Riccardo (PSI, Villigen) ; Auchmann, Bernhard (PSI, Villigen) ; Besana, Maria Ilaria (PSI, Villigen) ; Duda, Michal (PSI, Villigen) ; Fortunati, Reto (PSI, Villigen) ; Garcia Rodrigues, Henrique (PSI, Villigen) ; Hauenstein, Dominique (PSI, Villigen) et al.
The PSI Positron Production experiment, known as $\text{P}^{3}$ or $\textit{P-cubed}$, is a proof-of-principle positron source and capture system that can greatly improve the state-of-the-art positron yield. The $\text{P}^{3}$ project is led by the Paul Scherrer Institute in Switzerland, and addresses the long-standing challenge faced by conventional injector facilities to generate, capture, and damp the emittance of high-current positron beam, which is a major limiting factor for the feasibility of future electron-positron colliders.

We have produced hard x-ray free-electron laser (FEL) pulses, which are chirped both in photon energy and in
spatial position. The experiments have been carried out at the hard x-ray beamline Aramis at SwissFEL, located
at the Paul Scherrer Institute in Switzerland [...]

Dielectric laser acceleration for dark sector studies
/ Dadashi Motlagh, Raziyeh (Ecole Polytechnique, Lausanne) ; Ischebeck, Rasmus (PSI, Villigen) ; Jacobsson, Richard (CERN) ; Juranic, Pavle (PSI, Villigen) ; Niedermayer, Uwe (Darmstadt, Tech. U.) ; Zimmermann, Frank (CERN) ; Seidel, Mike (PSI, Villigen)
For the purpose of indirect search of dark matter, we designed laterally driven Dielectric Laser Acceleration (DLA) structure that achieves 1.2 MeV energy gain in 6 mm length together with 6D confinement. The design originated from a relativistic DLA structure and was supplemented with non-homogeneous shapes following the APF segments and optimized using a genetic algorithm together with the DLAtrack6D tracker.

An X-ray free-electron laser with a highly configurable undulator and integrated chicanes for tailored pulse properties

X-ray free-electron lasers (FELs) are state-of-the-art scientific tools capable to study matter on the scale of atomic processes. Since the initial operation of X-ray FELs more than a decade ago, several facilities with upgraded performance have been put in operation. [...]

The FCCee Pre-Injector Complex
/ Craievich, Paolo (PSI, Villigen) ; Alharthi, Fahad (IJCLab, Orsay) ; Auchmann, Bernhard (PSI, Villigen) ; Bartmann, Wolfgang (CERN) ; Benedikt, Michael (CERN) ; Besana, Maria Ilaria (CERN) ; Bettoni, Simona (PSI, Villigen) ; Braun, Hans-Heinrich (PSI, Villigen) ; Calviani, Marco (CERN) ; Chaikovska, Iryna (IJCLab, Orsay) et al.
The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.

SwissFEL Aramis beamline photon diagnostics
/ Juranic, Pavle (PSI, Villigen) ; Rehanek, Jens (PSI, Villigen) ; Arrell, Christopher A (PSI, Villigen) ; Pradervand, Claude (PSI, Villigen) ; Cassar, Ariana (U. Malta) ; Calvi, Marco (PSI, Villigen) ; Ischebeck, Rasmus (PSI, Villigen) ; Erny, Christian (PSI, Villigen) ; Heimgartner, Peter (PSI, Villigen) ; Gorgisyan, Ishkhan (CERN) et al.
The SwissFEL Aramis beamline, covering the photon energies between
1.77 keV and 12.7 keV, features a suite of online photon diagnostics tools
to help both users and FEL operators in analysing data and optimizing
experimental and beamline performance. Scientists will be able to obtain
information about the flux, spectrum, position, pulse length, and arrival time
jitter versus the experimental laser for every photon pulse, with further
information about beam shape and size available through the use of destructive
screens. [...]
