On Mar. 15 we received word from NSF that the final year of funding for the Critical Component Demonstration phase of the neutron electric dipole moment experiment (nEDM) is approved for release. The Illinois group (Beck, Peng, Williamson, Koivuniemi, Thorsland, Blackburn, Sobel, Rao, Sharma) is responsible for the so-called helium-3 services subsystem of the experiment. These funds will allow us to complete the dilution refrigerator, under construction at NPL, and used to cool the subsystem, as well as to make progress on components of both its injection and purification assemblies. The NSF also re-stated its commitment to provide $5.8M for the Large Subsystem Integration activities to follow the CCD phase of the experiment and to be shared between Illinois and Caltech.
