E835 Hydrogen Gas Jet
The hydrogen jet is formed by the nozzle and the cryogenerator, provides a hydrogen clusterized flow.The hydrogen gas passes through a liquid nitrogen cold trap. This filter eliminates any risk of the nozzle clogging with frozen gas. With a skimmer system in front of the nozzle, a solid angle of 1.5 degree is selected to form the target. Anti-protons collide with the hydrogen clusterized beam.
