Turned off the HV and the optics in the first section. Couldn't turn off the optics in the second section: left a message for Evgeniy.

Also TMS:RP2 is very noisy. Talked to Edi D. from vacuum group. He would work on it this afternoon. E-Fault#6282

Friday, August 31, 2012, 11:39: Stopped turbos.

Friday, August 31, 2012, 13:06: Venting.

Friday, August 31, 2012, 13:23: Water lines purged.

Started the cooldown for SiC#3.

All TPS optics, with the exception of TPS:Q4 cannot be turned off. E-Fault#6395 for Controls.

Same for the TSG optics: CB1, VCB1 and CBC.

Talked to Evgeniy and Kazuya. Optics are OFF now.

Venting the Test Stand.

TiC#3 will be ready to be removed in few minutes. 

Please note: water is still ON.

Target looks OK. The right leg was a bit much out of center and will be adjusted in the lab.

The torque required to loosen the bolts were measured (from left to right):

Target legs: 48 and 30 in lbs

Tube htr: 25, 30 and 25 in lbs

Monday, November 05, 2012, 14:41: Roughing

Monday, November 05, 2012, 14:58: Started turbos

Monday, November 05, 2012, 15:06 : Turbos at speed

Monday, November 05, 2012, 15:068: Vacuum at 2.2E-5 T

Wednesday, November 07, 2012, 08:26: Cooling water open. Vacuum stable at 1.8E-7 T

new ion guide laser ion source installed. Pure target container without targetmaterial and without surface ion source.

Heat up to 580A for heat test of all components. Distance between target and repeller < 1mm

13:15 start heating TGHT, 1A per 30sec vacuum below 2E-7T

14:50 reached 200A at TGHT (1.5V readback same as frontpanel), vacuum now 2.9E-7T, proceed on to 400A

16:10 TGHT 350 A (setpoint, readback stopped at 269A) and 3.4V readback, sudden increase in vacuum from 4E-7T to 5.5E-7T and larger fluctuations, give it 10min

16:22 vacuum back to 4.4E-7T but some occasional vacuum spikes , proceed to 400A

17:00 at 400A / 4.13V, vacuum hit 2E-6T in between which delayed the heating, now decreasing, will goto 410A for half an hour and then 385A over night

Dec 12th

8:30 3.3E-7T Vac at 385A, goto 420A

8:50 7.5E-7T Vac at 420A, goto 450A

9:20 1.7E-6T Vac at 450A, goto 470A

10:00 1.5E-6T Vac at 470A / 4.5V

11:30 1.1E-6T at 520A/4.56V

Wednesday, December 12, 2012, 11:46   1.7E-6T at 550A/4.58V

Wednesday, December 12, 2012, 14:31 

     580A reached,  Vacuum dropped from 1.8E-6T to 5.8E-7T in 2h

     voltage read back is wrong as well Panel readings are 572A/6.99V (read back values in EPICS are 248A/ 4.6V) 

Wednesday, December 12, 2012, 14:47 6.5E-7T at 592A/ 7.31V (Panel readings)

Wednesday, December 12, 2012, 15:01 there is no contact of the target to HV GND (especially the repeller), the target can still be biased to 5V

Wednesday, December 12, 2012, 19:48     5.9E-7Tvacuum is slowly going down now

Thursday, December 13, 2012, 00:23   5.5E-7T, start cooling down

Short summary on results of first heating teest with the Ion Guide Ion source:

The Ion source is still in good shape, nothing was effected by the heat. Just some deposition in the repellers and the exit electrode

The capton wires used for  wiring the electrodes had some problem with heat and went black and got brittle - for the next test we will ad a Ta schield at the side of the source to prevent radiation inside the source.

Friday, December 14, 2012, ~ 17:00: start roughing pumps

Friday, December 14, 2012, 20:33: start turbo pumps

Friday, December 14, 2012, 20:42 : turbos at speed

Friday, December 14, 2012, 20:43 :  vacuum at 7.32E-6T

Monday, December 17, 2012, 12:53 vacuum at 1.77E-7T

Tuesday, December 18, 2012, ~ 13:00 start ramping the TGHT current, vacuum at 1.7E-7T

Tuesday, December 18, 2012, 15:56: @ 250A, target is glowing, center block is cooler (can be inspected with a new hole in the heatshield lid), thermocouple is reading 224C, which is definitely colder than the temp from visual insepection, reading may be corrupted from contact to Heatschield

Tuesday, December 18, 2012, 23:11: target at 600A(593A/7.35V Panel reading), vacuum was up to 1.7E-6T, now 1.34E-6T. temperature reading was 405C which is quite away from glowing. Nevertheless, the center block of the target is visibly colder than the legs, while the center support is still way colder then the block. Thermocouple readback removed from HV cage. since the is a short cut the target (thermocouple?) the RFQ can be biased to 18V for suppression. everything locked up and stat HV test.

Wednesday, December 19, 2012, 00:14: target at 600A(593A/7.35V Panel reading), vacuum at 8.5E-7T, first HV test done, up to 30kV some occasional sparks. RFQ (1MHz , 40Vpp) without bias--> no signal, RFQ -9V biased --> 1.5E-11 on TMS:FC0

Wednesday, December 19, 2012, 01:17 : vacuum at7.7E-7T, start cooling down, was ~ 2.5h at max current.
