On shift: MO, MN Logbook n.7, pag. 148-153 8.35: Stop stacking with 55.4 mA. 11.30: S.Werkema called to say that they had cooling problems. 12.25: 1st ramp deceleration ends with 51.91 mA. 13.25: 2nd ramp deceleration ends with 51.29 mA. (Ecm=3526MeV) 14.00: Pedestal run 5596, written on db. 14.40: The beam is now stable. Jet target turned on at low density. The density was gradually raised from 0.5 to 0.9 x10^14 cm^-3 (final values: PBG_OR = 1.17 MHz, H2_OR = 1.5 MHz). 14.55: Run 5598 started with 50.59 mA. After frequent DAQ hangs related to DYC1, run was stopped, and KEG replaced the bad DYC. Integrated luminosity taken: 35.78 nb^-1 15.53: Run 5599 started with 49.76 mA (in progress). COMMENTS: - KEG found in PRUDE the problem which caused the synchronization DAQ hangs. - GL implemented a new program which checks HV every 10 min and beeps if something wrong is found. cheers Margherita e Matteo which checks HV every 10 min and beeps if something wrong is found. cheers Margherita e Matteo
