To reduce the operating noise in liquid hydrogen targets, the amount of material in the beam entrance and exit windows should be minimal. Lawsonite is a good material for target windows, since a sheet of Lawsonite is strong, keeps its elasticity at low temperatures, has a low density and small Z. A

The consumption of liquid hydrogen in this target is exactly the same as in that described above. One can work with an electron beam without ref'dling with hydrogen for 4 to 5 days. If necessary, the hydrogen reservoir and one of the targets can be f'dled with liquid He 4 and the other with He 3 by
