Ultra-clean magnetically-coupled piston pump for noble gas experiments. — •Andria Michael1, Lutz Althüser1, David Koke1, Christian Huhmann1, Michael Murra1,2, Philipp Schulte1, Henning Schulze Eissing1, and Christian Weinheimer1 for the XENON collaboration — 1Institut für Kernphysik, Universität Münster, Germany — 2Columbia University, New York, USA
The high performance magnetically-coupled piston pump is interesting for the usage in low background experiments dealing with noble gases as target. In such ultra-clean experiments, pumps are used for the circulation of the target material. Therefore, the reduction of radioactive emanating materials such as radon is of great importance. For this purpose, a radon-free, hermetically sealed, ultra-clean magnetically-coupled piston pump was developed (JINST 16 (2021) P09011) to be operated as a xenon gas compressor for the XENONnT experiment.
The magnetically-coupled piston pump is made of four cylinders connected in parallel, featuring a high flow by keeping high pressure differences for a good compression. The custom-made control gives the possibility to operate the system with different configurations and to monitor the status of each pump during the operation.
In this poster the function and the operation experience with this magnetically-coupled piston compressor is presented.
