A liquid xenon development and test system

Large liquid xenon detectors became rather popular in the last years, especially for Dark Matter searches. However, each new experiment or application presents its own specifications and requirements which first have to be explored with a small set up. Although much cheaper and easier to operate, a small liquid xenon system is nearly as complex as a large one. A small test set up is described as platform for such preliminary tests. The set up was thoroughly tested during the last two years of operation, and there are four identical systems running in different labs. The design is intended to be versatile and can be used as basis for similar instruments, whereas a complete new design would still cost several months of design, acquisition of parts, construction, assembly, and testing
