Research Abstract |
A detector which enables the KL beta decay search experiment has been developed.A thin gap chamber is constructed with cathodes of 12-um thick aluminized mylar film and a 1.6-mm-thick gas volume of CF4 and n-pentane gas mixture. In spite of its thickness of 5mg/cm2, it can be operated in high-flux neutron and gamma beam line with 99% charged particle efficiency. It was tested in the actual high intensity KL beam line and was proved to be operated stably in it with an allowable hit rate.
