Abstract

The characteristics of a liquid-hydrogen target with a CH-208L cryocooler used to cool the target and produce liquid hydrogen are considered. The main components of the developed setup are a cryostat, a condenser, containers for liquefied hydrogen, a vacuum pumping system, and thermometry devices. The rates of hydrogen liquefaction in the cryocooler mode without a first-stage heat exchanger have been measured. The obtained values range from 50 to 100 mL/h, depending on the measurement conditions at containers with volumes of 150 and 500 mL. The filling capacity of the 150 mL container has been visually checked, and the 500-mL container has been checked by the curves of liquid hydrogen evaporation into the receiver. When the required liquid-hydrogen levels are reached, the filling of containers is stopped by activating the hydrogen pressure stabilization mode. The corresponding stabilization system has been developed using the functionality of the available temperature controller.
