| Abstract |
| | Purpose. Diamond ionizing radiation detectors are highly resistant to radiation and might be used on the outer surface of the spacecraft. This determines the prospects for their application as space radiation monitors. To recover the spectra of cosmic radiation from the output of the detector, a mathematical model has been developed that describes the transformation of information in a diamond detector.
Methods. The output of the detector is the spectrum of signal amplitude which is proportional to the energy transferred to diamond sensitive element by ionizing radiation. The proportionality coefficient is determined experimentally analyzing the detector output under action of neutron radiation. So the simulation of the detector output means the simulation of transferred energy spectra. We use Geant4 simulation to obtain these spectra for electron and proton radiation. Simulation of the detector output has been carried out using the spectra of space radiation approximated by power functions.
Results and discussion. The spectra of energy transferred to diamond sensitive element have been obtained. The energy transferred by the electrons is from 3 to 10 times less than that transferred by protons so the signals of electrons and protons are distinguished easily. The output spectra of the detector under action of hard and soft electrons are similar so additional registration channels are required. The output of detector under action of hard proton radiation differs from that for soft proton radiation so the initial energy spectra might be recovered. The data obtained are to be used in neural network learning for processing the detector output. |
