The tissue-equivalent proportional counter (TEPC) is the reference detector of experimental microdosimetry. Commercial TEPCs are able to measure in sites larger than 1 µm of simulated diameter and in low-intensity radiation fields. However, both in radiobiology and in radiation protection there is interest to measure in less than 1 µm sites. Moreover, for monitoring therapeutic hadron beams TEPCs ought to work in very high charge particle fluxes. We have constructed both TEPCs able to measure down to 25 nm of simulated site size and TEPCs capable to monitor the microdosimetric features of intense therapeutic beams. In this paper we are describing the technical features of these detectors and some experimental results.

Abstract

The tissue-equivalent proportional counter (TEPC) is the reference detector of experimental microdosimetry. Commercial TEPCs are able to measure in sites larger than 1 µm of simulated diameter and in low-intensity radiation fields. However, both in radiobiology and in radiation protection there is interest to measure in less than 1 µm sites. Moreover, for monitoring therapeutic hadron beams TEPCs ought to work in very high charge particle fluxes. We have constructed both TEPCs able to measure down to 25 nm of simulated site size and TEPCs capable to monitor the microdosimetric features of intense therapeutic beams. In this paper we are describing the technical features of these detectors and some experimental results.
