The MicrostatHe Rectangular Tail works on a continuous flow principle using an oil-free pump to draw liquid helium from a storage vessel along a transfer tube to the heat exchanger ('pull mode'). Temperature control is achieved by a combination of automatic or manual helium flow control and power dissipated in an electrical heater, regulated using a temperature controller.

The cryostat can also be used in 'push mode', in that case the flow of liquid helium is generated by pressurising the storage dewar. The advantage is that the need for a gas flow pump is removed thus saving cost and eliminating the noise and vibration generated by the pump.

Had a great evening yesterday, networking with low temperature physicists over a reception at DPG Spring Meeting, s…
