Multiwire proportional counter
The multiwire proportional counter is a new type of detector developed in the late 60s. Using this detector to detect charged particles has the advantages of high detection efficiency, spatial resolution and good time resolution.
The window material of proportional counter is aluminum polyester film foil. The effective diameter of the window is 60mm, the thickness of the thin window is about 2 m, and the thin window is convenient for the particles with weak penetrability such as alpha and beta to enter the counting tube.
Detection efficiency (2 pi)
Alpha source: 241Am > 80%
Beta source: 90Sr-90Y > 45%
14C > 40%
It can also be customized according to the size required by the user.
