Edi replaced the faulty turbo pump in the mass separator section.

Roughing and turbo started

vacuum @ 9E-7T after 2.5h

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

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

By Sebastian (SR) & Henning

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

Edi called to inform that he can replace the turbo today.

Tuesday, March 19, 2013, 09:03: Stopped TP6

Tuesday, March 19, 2013, 09:35: Venting

Tuesday, March 19, 2013, 09:48 : TMS section and backing line vented

The turbo pump has been replaced see

Some heat marks were observed on the turbo pump that was replaced. Vacuum group took pictures.

Monday, January 28, 2013, 15:45: Vacuum at 3.9 E-6 T

 For conductor bolt work

Monday, January 28, 2013, 12:56: Turbos off

Monday, January 28, 2013, 14:18: Venting

 The temperature of the cooling water was logged during this test. See attachments for details. Note that current and voltage read back is not available due to trouble with the power supply. One thermocouple (Heat Shield circuit) came loose before the end of the test (not shown in plot).

After the last test at the test stand, one of the conductor bolts (ITD0058) is damaged. To prevent damage to the thread inserts, all conductor bolts will be replaced with new ones.

The optics at the teststand has been switched on, but TMS:CBC1 is not working. A fault report has been send to controls.

Started heating the target, now Silica sleevings are installed for wire insulation and the gap target -- repeller is now 0.6mm (was 0.25mm)

Target installed with 120 in lbs torque on target legs and on central support.
