Development of a Scintillating Fiber Tracker as a Beam Monitor for Sub-Therapy Particle Rates at the Marburger Ion Beam Therapy Center — Theresa Heinz1,2, Kai-Thomas Brinkmann1, •Lara Dippel1, and Hans-Georg Zaunick1 — 12nd Physics Institute, Justus Liebig University Giessen, Germany — 2D-PHYS, Institute for Particle Physics and Astrophysics (IPA)
This work presents the characterization and development of a scintillating fiber detector intended to be used as a beam monitoring system at the Marburg Ion Beam Therapy Center (MIT) for sub-therapy particle rates, where the in-house monitoring systems fail. The central focuses are the investigation of primary particle rate limitation and detector dead times, which were studied through dedicated measurements. These measurements provide performance benchmarks for future integration into various experimental setups which require lower particle rates.
Additionally, the development of the next detector version which contains more fibers and improves spatial resolution will be presented. Preparations for an FPGA-based readout system are carried out, enabling on-board logic for versatile detector operation. Geant4 simulations were carried out to validate the new detector design.
