Improvements due to NE Transferline Vacuum pumping
During the CEBAF maintenance day the NE Transferline Insulating Vacuum (CTLis 115630) was pumped. The graphs show a reduction in CHL2_2K Cold Box inlet temperature and a reduction in the speed of Cold Compressor 4. The majority of 81kW in electrical power reduction is likely due to the improved vacuum. A minority of the power reduction is due to an oil injection adjustment of the main compressors to improve efficiency.
