title: MICRODOSIMETRIC MEASUREMENTS OF A TISSUE-EQUIVALENT PROPORTIONAL COUNTER BASED ON A GAS ELECTRON MULTIPLIER DOWN TO 140 nm SIMULATED SITE SIZES.
abstract: A multi-element tissue-equivalent proportional counter (TEPC), based on a gas electron multiplier, has been constructed with several cavities of small dimensions (down to 0.5 mm of diameter), to be used for microdosimetric measurements in intense, pulsed, radiation fields. First micro- and nano-dosimetric spectra with low-energy X rays in various simulated tissue site sizes are presented. The specific advantages and the calibration methods of this type of TEPC are discussed.
