FIELD: physics.
SUBSTANCE: proposed device and method for determining characteristics of particle beam, at which reception of particle beam is provided in central region of casing with lower pressure; exposure by received beam on impact plate for beam, which is thermally isolated from casing; impact plate temperature change is measured for beam due to measuring of beam impact, pressure change is measured in casing due to receiving of beam; and measured temperature change and measured pressure change are processed in order to determine characteristics of beam.
EFFECT: improved dosimetry to control processing of parts.
