On the basis of previous results obtained with a two-stage pulse tube cooler that was able to provide a net cooling power of up to 0.37 W at 4.2 K, a somewhat modified version has been built to use it for small scale 4 He liquefaction. This paper presents first results obtained with this liquefier,

DC flow was found to exist in most double-inlet pulse tube coolers from theoretical simulations. DC flow effects in a 4 K pulse tube cooler were studied by numerical analysis and experiment. Numerical predictions show that a negative DC flow from the hot end of the pulse tube to the inlet of regener
