MicroBooNE moves into Phase 1

The MicroBooNE project has received approval to operate Phase 1 and is making final preparations to cool down. Phase 1 includes the purification filters and pumps for removing contaminants from liquid argon to the low parts-per-billion level. A high-voltage test cryostat is a new device installed at the Liquid-Argon Test Facility and will allow detailed measurements of the ability of liquid argon to hold large voltages at varying purity levels and different geometries of electrodes in a large-scale system.
