Multi-wire proportional counter

The multi-wire proportional counter is a new type of detector developed in the late 1960 s. Using this detector to detect charged particles has the advantages of high detection efficiency, good spatial resolution and time resolution.

The window material of the proportional counter tube is aluminum polyester film foil. The effective diameter of the window is ф 60mm, and the thickness of the thin window is about 2 µm. The thin window is convenient for particles with weak penetration ability such as α and β to enter the counting tube.

Detection efficiency (2π)

Alpha source: 241Am ≥ 80%

Beta source: 90Sr-90Y≥ 45%

14C ≥ 40%

Can also be customized according to the size of user requirements.
