Περίληψη: Objectives: This work presents the design, development, and initial proof-of-concept testing of a dosimetry device intended for FLASH radiotherapy.
Methods: The system incorporates organic scintillating fibers coupled to a silicon photomultiplier (SiPM) and an FPGA-based readout, with fiber geometry optimized to minimize perturbations to a clinical proton beam, as confirmed through measurements at the Huntsman Cancer Institute (HCI).
Results: Tests using a portable X-ray unit demonstrated a strong correlation between integrated charge and delivered dose (up to ∼35 mrem s-1) and showed that the detector can respond on nanosecond timescales, enabling rapid safety interlock triggering with minimal latency.
Conclusion: Preliminary proton irradiations at HCI further indicated that the device can resolve individual beam pulses, a capability valuable for both FLASH research and conventional radiotherapy.
Advances in Knowledge: These results highlight the need for continued refinement of the experimental setup, readout electronics, and detector performance to fully realize real-time, in situ dose and pulse monitoring.
