DETECTING UNIT OF ALPHA PARTICLES Russian patent published in 2014 - IPC G01T7/04 

Abstract RU 2522936 C2

FIELD: instrumentation.

SUBSTANCE: detecting unit of alpha particles comprises a chamber with inlet and outlet openings for the airflow, on the path of which in the chamber housing the filter and the detector of alpha particles detained by the filter are located one above the other, and an electronic unit of processing and analysing the signals electrically connected with the detector. The chamber is made dismountable, consisting of interconnected housing flanges of the instrument compartment and the compartments of the gas inlet and outlet, sealed by the flanges using O-rings. The detector is hermetically placed in the holder using two sealing rings, at that the holder which is hermetically mounted in the housing of the instrument compartment, is equipped with an outer spiral trough, forming a channel for communication of the cavity at the side of the front surface of the detector with the cavity at the side of the rear surface of the detector. The filter is secured to the mesh substrate and is placed into the filter holder hermetically mounted in the housing of compartment of the gas supplying. In the cavity between the working surface of the filter and the face surface of the detector the reference radiation source U-235 is mounted, at that the chamber is made of stainless steel.

EFFECT: increase in reliability of the device.
