In order to ensure the operation of cryogenic detectors as well as cryogenic preamplifiers and multiplexers in the vicinity of the sensor, the use of coolants is necessary. These must be brought to the test object using helium cans and transfer lines.

A helium lifter is to be procured as part of this tender. Since the measurements are also carried out in the field, a highly efficient handling of liquid helium is required, whereby the cryostats to be filled have a volume of 5 to 10 liters. Therefore, the jack must be made in one piece and completely rigid. A possibility of flow control (needle cold valve) is required.
