Impact of the neutral molecule trapping on beam lifetime and beam profile
/ Franchetti, G (Darmstadt, GSI) ; Zimmermann, F (CERN)
This proceeding addresses the effect of the neutral molecules trapped by the beam. It is in particular discussed the effect of a non-uniform neutral molecule distribution on the beam profile and the resulting beam lifetime. [...]

3D Polarisation of a Structured Laser Beam and Prospects for its Application to Charged Particle Acceleration
/ Polak, K (CERN ; Liberec Tech. U.) ; Gayde, J C (CERN) ; Sulc, M (Liberec Tech. U. ; Prague, Inst. Plasma Phys.)
A Structured Laser Beam (SLB) is a type of optical beam with spatially inhomogeneous 3D polarisation structures. Generating SLBs from vector beams allows the creation of Hollow Structured Laser Beams (HSLB) with a dark central core. [...]

Commissioning of X-LAB: a very high-capacity X-band RF test stand facility at the University of Melbourne
/ Volpi, Matteo (Melbourne U.) ; Giansiracusa, P J (Melbourne U.) ; Sheehy, S L (Melbourne U. ; ANSTO, Menai) ; Williams, S D (Melbourne U.) ; Rassool, R P (Melbourne U.) ; Taylor, G (Melbourne U.) ; Pushkarna, P (Melbourne U.) ; Dowd, R T (ANSTO, Menai) ; Zingre, K (ANSTO, Menai) ; Boronat, M (CERN) et al.
The Compact Linear Collider (CLIC) beam-based acceleration baseline uses high-gradient travelling wave accelerating structures at a frequency of 12 GHz. In order to prove the performance of these structures at high peak power and short pulse width RF, two klystron-based test facilities will been put in operation this year. [...]

A new hydrogen-filled Cherenkov detector for Kaon tagging at the NA62 experiment at CERN
/ Sanders, Jack (Birmingham U.)
/NA62 Collaboration
The precision measurement of $K^{+} \rightarrow \pi^{+} \nu \bar{\nu}$ at the NA62 experiment requires a kaon identification detector to have a time resolution better than 100ps, at least 95% kaon identification efficiency, and a pion misidentification probability of less than $10^{-4}$. Since the start of NA62 data taking in 2016, kaon identification has been performed by a differential Cherenkov with achromatic ring focus (CEDAR) detector with a nitrogen gas radiator. [...]

Improvement of the longitudinal phase space tomography at the J-PARC synchrotrons
/ Okita, H (J-PARC) ; Tamura, F (J-PARC) ; Yamamoto, M (J-PARC) ; Nomura, M (J-PARC) ; Shimada, T (J-PARC) ; Saha, P K (J-PARC) ; Yoshii, M (J-PARC) ; Ohmori, C (J-PARC) ; Sugiyama, Y (J-PARC) ; Hasegawa, K (J-PARC) et al.
The longitudinal phase space tomography, which reconstructs the phase space distribution from the one-dimensional bunch profiles, is used in various accelerators to measure longitudinal beam parameters. At the J-PARC, an implementation of the phase space tomography based on the convolution back projection method has been used to measure the momentum spread of the injected beam. [...]

Tailoring transverse beam characteristics with the new CERN PS Booster charge-exchange injection system
/ Renner, E (TU Vienna) ; Albright, S (CERN) ; Antoniou, F (CERN) ; Asvesta, F (CERN) ; Bartosik, H (CERN) ; Bracco, C (CERN) ; Di Giovanni, G P (CERN) ; Mikulec, B (CERN) ; Prebibaj, T (CERN) ; Skowronski, P (CERN) et al.
A key aspect of the LHC Injectors Upgrade project is the connection of the PSB to the newly built Linac4 and the related installation of a new 160\,MeV charge-exchange injection system. The new injection system was commissioned in winter 2020/21 and is now used operationally to tailor the transverse characteristics for the various beam types at CERN, such as high-intensity fixed target beams, LHC single bunch beams, and high-brightness beams for LHC.
