DESCRIPTION:Speakers: Rodion Faradzhaev (National Research Nuclear Univers
 ity MEPhI)\nA calibration system based on two light-emitting diodes (LEDs)
  and finite difference technique is described. Pulses of the both LEDs hav
 e a complex shape like CsI(Tl) signals. The first LED has constant amplitu
 de\, while the amplitude of the second one varies all over the detector en
 ergy range. The differences between detector responses to summarized pulse
 s of the both LEDs and pulses of the variable LED are measured. Then itera
 tive fitting of the measured data is used for calculation of a detector re
 sponse curve. This approach allowed us to design a calibration system for 
 a scintillation detector with the energy range of 1-200 MeV\, which is goi
 ng to be part of the GRIS solar gamma ray spectrometer. The results of cal
 ibration and verification measurements are represented\; the precision of 
 the proposed method is discussed.\n\nhttps://indico.particle.mephi.ru/even
