Abstract
We have constructed a large new dilution refrigerator for use with the new Lancaster nuclear cooling facility. The machine is housed in a purpose-rebu ilt suite of rooms and has been designed to have a very low base temperatur e, a very low heat leak environment and to run for long periods between ref rigerant refills. The machine has been operated in continuous mode down to similar to 1.75 mK and can run for 10 days between refills. Preliminary nuc lear cooling experiments suggest that even with an experiment attached the mixing chamber can still run below 2 mK.
