Investigation of Ionization Chamber Characteristics for Ultrahigh-dose-rate Scanned Carbon-ion Beams.

Background/aim: There are only a few studies on dosimetry with ultrahigh-dose-rate (uHDR) scanned carbon-ion beams. This study investigated the characteristics of four types of ionization chambers for the uHDR beam.

Materials And Methods: We employed a newly developed large-plane parallel chamber to monitor a 208.
