Description
The detection system of the Dubna gas-filled recoil separator (DGFRS) aimed at the studying of the SHE nuclei and their decay properties has been modernized during last few years. The new set of multistrips double-sided silicon detectors (DSSD) in focal plane of DGFRS is applied now instead of the old array of 12-strips position-sensitive Si detectors. The total amount of measuring spectroscopic channels of the registering system has increased also up to 224 channels. It leads to more precise measuring of the energy and coordinate of the implanted nuclei of the SHE into the focal detectors and of their decay products. It is important to test the registering system and perform energy calibration before carrying out of such unique experiments on the synthesis of new nuclei from the “Island of stability”. This work is devoted to describe the designed method and produced specific digital module which allows to perform energy calibration for all 224 individual spectroscopic channels independently. This device provides automatic bypassing of the all individual channels one after another, and thus imitating charge particles incoming to the detectors. Energy of the imitating signal can be chosen from the range of 1 MeV up to 250 MeV with good amplitude linearity and stability.
