/ Senes, Eugenio (CERN) ; Burrows, Philip N (JAI, UK ; CERN) ; Corsini, Roberto (CERN) ; Farabolini, Wilfrid (CERN) ; Gilardi, Antonio (LBNL, Berkeley) ; Krupa, Michal (CERN) ; Lefèvre, Thibaut (CERN) ; Mazzoni, Stefano (CERN) ; Pakuza, Collette (CERN ; JAI, UK) ; Wendt, Manfred (CERN)
The AWAKE experiment studies the acceleration of electrons to multi-GeV levels driven by the plasma wakefield generated by an ultra-relativistic and high intensity proton bunch. The proton beam, being considerably more intense than the co-propagating electron bunch, perturbs the measurement of the electron beam position achieved via standard techniques. [...]

The Advanced Proton Driven Plasma Wakefield Experiment (AWAKE) at CERN uses 6 cm long proton bunches extracted from the Super Proton Synchrotron (SPS) at 400 GeV beam energy to drive high gradient plasma wakefields for the acceleration of electron bunches to 2 GeV within a 10 m length. Knowledge and control of the position of both copropagating beams is crucial for the operation of the experiment. [...]

A beam position monitor based on Cherenkov diffraction radiation (ChDR BPM) is currently under investigation to disentangle the electromagnetic field of an electron bunch from that of a proton bunch travelling together in time and space in the beam-line of the AWAKE plasma acceleration experiment at CERN. The signals from a horizontal pair of ChDR BPM radiators have been studied under a variety of beam conditions at the CLEAR electron beam test facility. [...]

Beam studies using a Cherenkov diffraction based beam position monitor for AWAKE
/ Spear, Bethany (JAI, UK) ; Pakuza, Collette (CERN) ; Senes, Eugenio (CERN) ; Wendt, Manfred (CERN) ; Burrows, Philip (JAI, UK) ; Mazzoni, Stefano (CERN) ; Lefevre, Thibaut (CERN)
A beam position monitor based on Cherenkov diffraction radiation (ChDR) is being investigated as a way to disentangle the signals generated by the electromagnetic fields of a short-pulse electron bunch from a long proton bunch co-propagating in the AWAKE plasma acceleration experiment at CERN. These ChDR BPMs have undergone renewed testing under a variety of beam conditions with proton and electron bunches in the AWAKE common beamline, at 3 different frequency ranges between 20-110 GHz to quantify the effectiveness of discriminating the electron beam position with and without proton bunches present.

The CERN Linear Accelerator for Research (CLEAR) at CERN is a test facility using a 200 MeV electron beam. In 2020 and 2021, a few hardware upgrades were done: comparators for position measurements were added on components, the in-air experimental area was re-arranged in order to provide more space, a robotic system was built to enable remote samples manipulations for irradiation studies, the BPM reading system was optimized and the laser double-bunch system implemented to allow for a doubling of the electron bunch frequency from 1.5 GHz to 3 GHz.

Optimisation of a High-Resolution, Low-Latency Stripline Beam Position Monitor System for Use in Intra-Train Feedback
/ Blaskovic Kraljevic, Neven (JAI, UK) ; Bett, Douglas (CERN) ; Bodenstein, Ryan (JAI, UK) ; Bromwich, Talitha (JAI, UK) ; Burrows, Philip (JAI, UK) ; Christian, Glenn (JAI, UK) ; Perry, Colin (JAI, UK) ; Ramjiawan, Rebecca (JAI, UK)
A high-resolution, low-latency beam position monitor (BPM) system has been developed for use in feedback systems at particle accelerators and beamlines that operate with trains of particle bunches with bunch separations as low as several tens of nanoseconds, such as future linear electron-positron colliders and free-electron lasers. The system was tested with electron beams in the extraction line of the Accelerator Test Facility at the High Energy Accelerator Research Organization (KEK) in Japan. [...]

Testing the Properties of Beam-Dose Monitors for VHEE-FLASH Radiation Therapy
/ Bateman, Joseph (JAI, UK) ; Burrows, Philip (JAI, UK) ; Corsini, Roberto (CERN) ; Dosanjh, Manjit (CERN) ; Dyks, Luke (JAI, UK) ; Farabolini, Wilfrid (CERN) ; Gerbershagen, Alexander (CERN) ; Heracleous, Natalie (CERN) ; Korysko, Pierre (CERN) ; Morales Vigo, Sara (CERN) et al.
Very High Energy Electrons (VHEE) of 50 - 250 MeV are an attractive choice for FLASH radiation therapy (RT). Before VHEE-FLASH RT can be considered for clinical use, a reliable dosimetric and beam monitoring system needs to be developed, able to measure the dose delivered to the patient in real-time and cut off the beam in the event of a machine fault to prevent overdosing the patient.
