[en] The invention relates to the electrophysical equipment and can be used in high-current ion accelerators and in thermonuclear facilities. The device suggested is intended for absorbing charged and neutral particles with an energy from 10 to 100 keV leaving the operating region of an electrophysical facility. The purpose of the invention is to provide a long-term quasi-continuous operation of the device. This aim is achieved by making the housing of the device in the form of two chambers - receiving and regenerating ones. The joint between the latters is sealed by eccentric cylinders and receiving plates between them
