Thе paper describes a new E-*DE detection module which includes a position-sensitive double-sided strip detector (DSSD) and a low-pressure pentane-filled *DE 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 *4*8Ca ion beam intensity of about 5–7 p*mA (particle micro ampere) and the *DE counter count rate of approximately 104 sec*-*1, we observe a decrease in the overall registration efficiency of the gas *DE counter. The paper proposes a solution to this problem: introduction of an additional negatively biased electrode, which results in the stabilization of the *DE detector operation.
