Tuesday, March 19, 2013, 12:32 : Turbos off (vaccum at 2E-7 Torr)
Tuesday, March 19, 2013, 13:35: Venting
Target SiC#28 LP-RFQ inserted
New bolts used. Old bolts removed.
All bolts torqued to 120 in lbs
By Sebastian (SR) & Henning
modification of 9 Pin connector needed to match wiring in TM4 (see separate e-log entry)
Tuesday, March 19, 2013, 18:32 : started roughing - SR
Tuesday, March 19, 2013, 18:52: started turbos - SR
Tuesday, March 19, 2013, 18:57: TSGIP1 on - SR
Tuesday, March 19, 2013, 19:00: turbos at speed - SR
Tuesday, March 19, 2013, 19:02: vacuum at 1.68E-5T

Wednesday, March 20, 2013, 08:18: Opened cooling water. Vacuum stable at 6.8E-7 Torr

Wednesday, March 20, 2013, 11:39: 9PIN connector in HV cage connected
4,5,6,9 on GND 1,2 to RF, 7,8,RFoffest,Source for now also on GND
RF: 800kHz, 20Vampl, 0.128mA
HV cage locked up for heating
Wednesday, March 20, 2013, 16:42: heating is taken care of by ISAC operations, now at 300A / 3V TGHT and 250A / 1.47V TBHT reading on the panel is really close
Friedhelm restarted some of the CANBUS ports, since not all optics were working properly
Thursday, March 21, 2013, 10:53 start cooling down
Vacuum not perfect was around 2E-6T, over nigth not full current
Suppression tested yesterday: full beam (SRC +3V, others GND) was 40nA, while no signal on FB0B with SRC +3V, IGOffset&Exit +25V
!!!!! but short on #7 --> 2nd Repeller, was OK when tested, after some minutes on 25V short was there, reading now (Thursday, March 21, 2013, 10:58 ) <1OHM, will be checked while heating down
Magnet had wrong polarity - so no mass scans yesterday evening, Friedhelm looked into this this morning
Mass scan only for good transmission mode (SRC +3V) this morning - see attached scan (seen Na, Al, K, Ca, Cr, Rb, Sr, Cs and Ba)
Thursday, March 21, 2013, 12:26: stopped turbos
#7 still short
