✦ Synopsis

A liquid hydrogen target, containing 2501 of liquid hydrogen, with a ratio between the working space and the reservoir of 1.5: 1, is described. A radiation shield cooled by evaporating gas is used to insulate the target. The diameter of the beam windows is 30 cm. Mean quantity of hydrogen along the beam is 14. 35 g cm "2, the amount of other matter along the beam is O. 75 g cm 2 , and across the beam is 2. 75 g cm 2. Uncertainty in target length is not more than 1.5%, liquid hydrogen evaporation is 5 fitres per day, and operating time with refills is 20 days.

In order to increase the accuracy of measurements and the counting rate when working with liquid hydrogen targets, the amount of hydrogen in the path of the beam must be increased, the thermal insulation improved and the amount of extraneous matter both along and perpendicular to the beam must be re
