From the British Cryogenic Council newsletter:

Our first, urgent news is to tell you of the need to move Cluster Day forward to Tuesday September 20 this year, due to intergalactic events beyond the control of the Cryogenic Cluster.  We’re really sorry to make this change, and hope it will be possible for you all to accommodate this adjustment in the time available.

We’re planning talks at Cluster Day on the invention of Rutherford Cable (given by Martin Wilson), joining superconducting wires (with Greg Brittles) and Cryotherapy (from Agnieszka Piotrowska).
