Description

Laser-accelerated electron beams, in the so-called Very High-Energy Electron (VHEE) energy range, are of great interest for biomedical applications, particularly for developing compact accelerators for FLASH radiotherapy. Reliable real-time dose information is essential for radiobiology experiments using such laser-driven sources. We present an online dose-monitoring method based on an Integrating Current Transformer (ICT) paired with a dedicated collimator, enabling shot-to-shot dose estimation under well-defined assumptions. Cross-calibration with standard RadioChromic Film (RCF) dosimetry shows excellent agreement, confirming the accuracy and applicability of the ICT-based approach for experimental VHEE studies.
