J. Kissel, H. Radkins Hugh and I continue to investigate the corner station HEPI pump servo noise at its source. As such, we've switched the servo OFF and terminated the two pressure sensors used for the loop error point (read in as H1:HPI-PUMP_L0_BSC2SUP_PRESS, and H1:HPI-PUMP_L0_BSC2RET_PRESS) with 100 [ohms] at 3:45 pm (23:45 UTC). The hope is to quantify the servo's ADC noise floor. We intend to leave it in this configuration for an hour or so before restoring it. Meanwhile, Hugh continues to manually maintain the pump pressure (though very little has been required but for a few 1 [ct] tweaks).
