Posted below are the plots for the various PSL pressure, flow, and cooling signals post 70W and new shutter install. This should represent the final configuration of the reworked cooling system necessary to accommodate the new amp. Most changes reflected in the plots are as expected and should assist with final tuning and balancing the water flows. The goals of the tuning will be to (1) reduce pressures as much as possible while retaining enough flow to ensure proper cooling. (2) to shift pressure manipulations from within the PSL enclosure to the chiller room, and (3) to reduce water flow table noise to a minimum.
