Abstract
This article describes the design and working principle of a three-cel l liquid hydrogen target produced for the high-energy deuteron polarim eter HYPOM. This target uses liquid helium as a cooling agent. After a general description of the apparatus, tests and operating modes are t horoughly explained. In particular the air controlled self-regulation of helium flow in the cryostat to stabilize the liquid hydrogen level is presented. The main feature of this target is the simplicity of the design as well as its safeness towards any incident. Results of cooli ng down, filling up of the target and stabilization regime were proces sed during one experiment of physics at synchrotron Saturne II.
