Small dose monitor based on silicon-carbide diodes for FLASH radiotherapy. [PDF]

open access: yesMed Phys
Abstract Background The FLASH biological effect in radiotherapy has been observed to appear at ultra‐high dose rates UHDR (>$>$40 Gy/s), where the accurate dosimetry at such high rates is still a challenge. Purpose A new 4 ×$\times$ 4 array of SiC‐based detectors (1 mm diameter, 2.2 mm pitch) is proposed for dosimetry in UHDR, as well as the ...
