Description
A new design is proposed and described of a combined detector (CD) for simultaneous detection of charged particles and gamma-quanta. The CD comprises a single crystalline plate of ZnSe(Te) placed onto the output window of a scintillating transparent light transducer made of CsI(Ti) and Al2O3(Ti) in the shape of truncated pyramid. The CsI(Ti) light transducer is used to create an additional channel for detection of gamma-radiation,as well as for protecting the photodiode from the penetrating radiation.It is shown that introduction of such light transducer does not worsen the energy characteristics of ZnSe(Te). Separate detection of alpha- and gamma-radiation has been achieved under simultaneous excitation by 239Pu (ZnSe(Te), Ra=6%) and 241Am (CsI(Tl), Rγ = 20 %). The use of selective optical filters allows separation of the peaks of total absorption (p.t.a.) in the case of their superposition
