Click to enlargeThe bottom of the helium thumper (being held upside down). A helium thumper is a hollow metal tube which is inserted into a liquid helium dewar to check the level. The pressure oscilations which are set up inside the tube due to the warm metal coming into contact with the cold helium liquid and vapour above it change whether the bottom of the tube is submerged in liquid or not. These changes can be felt by an experienced cryologist who places his or her thumb over the top end of the tube, and then measuring at what position the change happens, corresponding to the level of liquid in the dewar. This one has just come out of a helium dewar, and its lower part is cold enough to condense the small bit of moisture in the highbay air.
