Welcome Home, Vacuum Insulated Liquid Nitrogen Cryogenic Storage Vessel!
Several years in the making, the liquid nitrogen dewar for the End Station Refrigeration 2 (ESR 2) has arrived on the lab campus. The ESR 2 system will feed cryogens to Halls A, B, and C, and it will replace ESR 1 by adding additional capacity to support the MOLLER Experiment.

Project Progress Summary
July 23, 1991
FET Operations
- Two lengthy runs were completed, one achieving 43-MeV operation with a 10-microamp CW beam. Radiation surveys were conducted to measure neutron levels near the beam dumps. These levels were found to be very low. An operator training session was held for four new beam operators.
