The cryostat for the PULSTAR systematics studies apparatus arrived last month! We’re currently commissioning the cryostat and performing first cool downs to 4.2K with liquid helium. We will then install a dilution refrigerator that will cool our 3 L volume of superfluid helium to below 0.3 K. The experiment will be situated inside the PULSTAR reactor and will use the new ultracold neutron source there to demonstrate the experiment techniques required for the success of the SNS nEDM experiment and will study many key systematic effects required to be understood, as our collaboration aims to discovery the never observed neutron electric dipole moment by reaching a sensitivity 2-orders-of-magnitude better than the current world wide limit.
