Feasibility study of radiation quality assessment with a monolithic silicon telescope: Irradiations with 62 AMeV carbon ions at LNS-INFN

Abstract The Segmented Monolithic Silicon Telescope, a two-stage detector recently proposed as a solid state microdosimeter, demonstrated to be capable of measuring the microdosimetric spectra of clinical proton beams similar to those measured by reference tissue-equivalent proportional counters. This work concerns the study of the possibility of exploiting this feature for carbon beam quality assessment. To this aim, the silicon device was placed in a polymethylmetacrylate phantom and irradiated with a 62 AMeV un-modulated carbon beam at the cyclotron facility of the Laboratori Nazionali del Sud of the Italian Institute of Nuclear Physics. The results of these preliminary measurements will be discussed in details.
