E-ΔE detection module of DGFRS-2 setup.

Thе paper describes a new E-ΔE detection module which includes a position-sensitive double-sided strip detector (DSSD) and a low-pressure pentane-filled ΔE chamber for detection of Evaporation Residues (ERs) in complete fusion reactions. The goal is to synthesize superheavy isotopes at the new DC-280 (Dubna Cyclotron) cyclotron of the Joint Institute for Nuclear Research (JINR). With the Ca ion beam intensity of about 5-7 pμA (particle micro ampere) and the ΔE counter count rate of approximately 10 sec, we observe a decrease in the overall registration efficiency of the gas ΔE counter.
