| Popis: | Microdosimetry with tissue-equivalent proportional counters (TEPC) has proven to be an ideal dosimetry technique for mixed radiation fields as those ones used in boron neutron capture therapy (BNCT). A new counter, composed of two twin cylindrical mini TEPCs inserted in a slim titanium sleeve of 2.7 mm external diameter, has been constructed. The detector has been designed to perform dosimetry and microdosimetry in intense radiation fields. The two mini TEPCs work in gas flow mode. They have right cylinder sensitive volumes of 0.9 mm. In spite of gas line tiny sizes, the gas pressure inside the two counters is well established with |
