Beam Loss Monitors (BLM)

A beam loss monitors (BLM) is a detector that makes use of the ionization effect of charged particles or gamma-rays on an internal gas. Very high sensitivity and short response times make BLMs suitable for beam protection systems that are necessary at proton accelerators and heavy ion beam accelerators etc.

Features

High sensitivity and short response time

Realization of sensitivity 1,000 times that of conventional ionization chambers and a microsecond response time makes it ideal for machine protection systems.

Improved operating life and shock resistance

Chemical cleaning and high-temperature exhausting under vacuum condition on the detector completely eliminates impurities. Dual tube structure substantially improves noise-resistance and facilitates measurement modes ranging from pulse through continuous.
