IPAC'23 - Student Poster Session Guide

IPAC’23 / STUDENT POSTER SESSION GUIDE 11 Student Poster Session A demonstrator experiment to support the UK-XFEL project is being discussed for the upgraded CLARA facility at Daresbury Laboratory. The experiment will scatter Ti:Sapphire laser pulses at 800 nm off 250 MeV electrons. The gammas will be collimated. This experiment will character- ise the source to determine the bandwidth and fux of the source. The maximum energy of the gamma photons in this experiment is 1.48 MeV and the bandwidth of the collimated source is 3.2%. In this work I will present simulations of the planned experiment, showing the scattered gam- ma energy, bandwidth and tunability of the source. SUPM008 A Novel Large Energy Acceptance Beamline for Hadron Therapy Adam Steinberg (Cockcroft Institute) . Jacinta Yap (The University of Melbourne), Robert Appleby (Cockcroft Institute), Suzanne Sheehy (Aus- tralian Nuclear Science and Technology Organisation). A design study is currently underway at the University of Melbourne for a large energy accep- tance beamline to enable future hadron therapy modalities. As part of the TURBO project, this beam delivery system will be demonstrated using DC Pelletron accelerator, conditioned for H+ and He+ beams up to 3.5MeV. Fixed Field Accelerator optics will be used to maximise momen- tum acceptance, and the dispersion must be minimised at both ends of the transport line for integration into existing or new facilities. This will be the first Fixed Field Accelerator ‘closed dispersion arc’ to be constructed. As part of the design process, the input beam phase space has been characterised and a matching section has been proposed. Our results show that the Pelletron beam can be injected into the novel transport line successfully, and simulations with Zgoubi show that almost zero dispersion will be achievable. This is supplemented by error acceptance studies for both the input beam parameters and the beamline magnetic fields, demonstrating that beam transport can be achieved under realistic circumstances. Now that this design has been completed, we can proceed with construction and testing of this beamline. SUPM009 A Compact Dielectric Grating-Based Charged Particle Bunch Length Diagnostic Device at ARES Blae Stacey (Deutsches Elektronen-Synchrotron) . Ralph Assmann, Thomas Vinatier, Willi Kuropka (Deutsches Elektronen-Synchrotron), Wolfgang Hillert (University of Hamburg). Dielectric gratings are used in Dielectric Laser Acceleration due to their high damage thresholds in high acceleration gradients. When an electron bunch passes close to these gratings, it emits radiation, and the features of this radiation will be dependent on the beam position relative to the grating, the bunch charge, and the bunch length. A compact high-resolution diagnostic device will be developed that consists of multiple dielectric gratings with different periodicities; these types of devices are required for the accurate operation of future compact accelerators which are currently undergoing development and testing.
