Abstract

A monolithic silicon ΔE/E microdosimeter has been developed in the last years. The proper design of the detectors, the custom electronics for front-end and acquisition, and the data correction the for the tissue- equivalence make the developed system a unique tool for the characterization of radiation fields. Recently, test runs have been performed at the CATANA facility (INFN-LNS, Catania, Italy) on the therapeutic 62 MeV proton beam line for ocular tumors treatments. Preliminary results are reported and discussed. The comparison of the experimental microdosimetric spectra with the ones measured with mini-TEPCs is fairly satisfactory.
