Description

The ISIS liquid methane moderator is now running regularly with pulsed neutrons from a 750 MeV proton beam at 100 μA intensity on to a depleted uranium target. Polymerization of the methane produces an oily contamination which threatens to cause blockages in the cryogenic system when still higher intensities are attained. This paper outlines some methods considered to address the problem and goes on to describe in some detail an on-line method of recharging the cryogenic system with fresh liquid methane without interrupting its operation
