Thursday, March 21, 2013, 14:46: started roughing

                Target was out, visibly inspected, nothing to be seen, no short on the target - wiring of the 9Pin connector shows short circuit inside vacuum chamber

                Wires removed - short could be reproduced with the strandings of the shielding  from the kapton twisted pairs going into the peek connector

               wire shieldings now fixed to position further away with Cu wire

               all wires against ground and each other tested for holding 250V - all fine

               everything reconnected and target put in, torcked w 120 inch pounds

Thursday, March 21, 2013, 15:05 : turbos started

Thursday, March 21, 2013, 15:14: turbos at speed

Thursday, March 21, 2013, 15:17: vacuum at 1.4E-5T

Thursday, March 21, 2013, 18:01: vacuum at 1.45E-6T opening water lines - vacuum is stable

Thursday, March 21, 2013, 19:19 : vacuum at 8.6E-7T - start ramping heater to 580A / 250 A

Friday, March 22, 2013, 00:08: target is heated full way up

           setpoint 570A and 7.250V voltage limit

           readback 564.1A and 7.201V  --> needs more voltage than the normal target !

           vacuum at 1.2E-6T

Friday, March 22, 2013, 15:15: vacuum at 5.4E-7T

         preparing for HV test and mass scan

        transmission mode: Source +3V, everything else on GND: 12nA - mass scan see attachment

       suppression mode 1: Source -15V, everything else on GND: 20pA - mass scan see attachment

       suppression mode 2: Source +3V, everything else on +25V: <1pA - FC0 current while biasing see attachment

       NOTE:  the legs of the target are glowing differently, the left leg (view from the lid side onto the target unit) glows brighter, this side was open during the sintering process of the SiC and needed more alignment at the jig --> see attached picture

       NOTE2: there is a slight increase in TGHT voltage over time: in ~ 22h from 7.201V to 7.216V

Friday, March 22, 2013, 21:33 : vacuum at 4.8E-7, start ramping down

Friday, March 22, 2013, 22:47: heaters down and turned off, vacuum at 2.7E-7T

Monday, March 25, 2013, 00:15: vacuum at 1.4E-7T, IG off, turbos off

Monday, March 25, 2013, 08:18: Venting

Monday, March 25, 2013, 08:33: Purging water lines

Monday, March 25, 2013, 08:42: Target removed

The powersupplies added to the teststand for operation of the IGLIS source have been removed from the HV cage as well as the RFQ driver.. The connections of the 9PIN connector in the HV cage have been grounded and the wire used for an voltage offset of the source has been removed.

NOTE: The Anode PS cable (used for biasing the target with a FEBIAD) is left grounded --> has to be rewired when running a FEBIAD source - Anode PS is turned off

Thursday, March 28, 2013, 13:55: Roughing

Thursday, March 28, 2013, 14:36: Starting turbos (vacuum at ~0.100 T)

Thursday, March 28, 2013, 14:44: Both turbos at speed

Thursday, March 28, 2013, 14:46: Vacuum at 5.2E-6 Torr

See Cyclotron e-fault 6637

Tuesday, April 09, 2013:

 Water leak has been repaired, but P/S could not be turned on. Ground interlock still latched. The base of the cabinet was filled with water - most of the water could be scooped out with a bucket.

Wednesday, April 10, 2013:

Removed the remaining water in the P/S rack.

Thursday, April 10, 2013:

The power supply is again operational. See e-fault entry above for details.

Tuesday, April 16, 2013, 08:59

The turbo was found in fault state this morning. Based on data from IG6 the pump stopped around midnight.

An attempt to restart the pump will be made after the conditioning of Ta#40 is complete later today.

The TP has recently been replaced:

Tuesday, April 16, 2013, 16:23: TMS:TP2 restarted I=1.0A P=21W T=29C @ 42kRPM

Wednesday, April 17, 2013, 16:19: TMS:TP2 I=0.8A P=14W T=29C @ 42kRPM

Friday, May 03, 2013

The anode cable has been reconnected to F/T J and the 100k resistor placed between L and J. Q is now grounded to L. See dwg ISK4523

Tuesday, May 07, 2013

The cathode cable has been reconnected to F/T B and the 100k resistor removed between L and J. See dwg ISK4563 Rev 3

Wednesday, May 08, 2013, 08:52: TMS:CB5 found off this morning. Switched back on.

Wednesday, May 08, 2013, 12:14: Lost the following devices during a mass scan

TMS:VCB5
TMS:OCT3
TPS:Q4
TPS:Q2
TPS:Q1
TSG:CBC

All devices but TPS:Q1 could be completely restored.

Wednesday, May 08, 2013, 12:49: TPS:Q1 restored by lowering and increasing the voltage

TSG:CG1A and TSG:CG1B shows an increase in vacuum.

See attached archived data for details.

Turbos stopped, waterlines flushed, chamber vented

Ceramic coated coil development target removed. CTL Febiad target installed.

Roughing chamber.

Turbos started

Cooling water turned on when vacuum reading 5.54e-06 T. Vacuum steadily increasing. Ion gauge reading steadily decreasing now reading 4.48e-06 T.

The cyclotron operators discovered a water leak in the magnet power supply. The water is valved off and the power is off. A fault report has been issued to the power supplies group.

Purged the gas lines, turned on the HV and started the heaters for CLT FEBIAD: TGHT up to 580A and TBHT up to 230A.

COIL and ANODE data added to ISACT Data Archiver

SOURCES ARCH was found not running

Friday, June 07, 2013, 08:42: Restarted Q2, Q4 and MB1
