Integrated measuring sensor for electron radiation parameters

Abstract

One of the most actual problems of the metrology is obtaining of information about several parameters measured with the help of one sensor. With the reference to the metrology of the electron radiation on the industrial accelerators such parameters can be particle flux (mean current of the beam), energy flow (power) and energy of electrons (average value). For solution of these problems the authors of the report designed the combined charge-calorimetric sensor (CCS) on the base of elaborated in VNIIM Faraday cup (FC) FC-1 from the State Measurement Standard of Russia GET 72-90 content. With the help of the soft ware package GEANT the computer model for radiation-sensor interaction was constructed, that allowed to receive quantitative data on leakages from the sensing volume of a charge and radiation energy. The measuring channel for the mentioned parameters of electron radiation in energy range 5...50 MeV was built. The experimental investigation of the channel on the specially built bench and accelerator LU-10 KIPT has been carried out.
