Tuesday, December 12, 2023, 16:07  - Pumping down test stand overnight for testing tomorrow. vacuum good, turbos starting now. Four thermocouples attached inside. tc1: high on (+) TGHT leg, pins 1+2. tc2: at target terminal (+), pins 4+5. tc3: at target terminal (-), pins 6+7. tc4: low on (+) TGHT leg, pins 8+9.

 Wednesday, December 13, 2023, 09:32 : Vacuum at 8.2e-7 T.  Electrical team is finishing connecting the cables. Claim it will be complete at 11am.

 Wednesday, December 13, 2023, 11:41Started both tc loggers at 11:40 - important for offset time. Beginning ramp as well on ATTS TGHT. set vacuum values high at 1e3 1e4 to bypass ATTS interlock, which does not apply here. ramping to 600A with step increment 10A and wait interval 10s.

    ATTS TGHT claims ramping in progress, but increased voltage is reported only on the autoramp window, which reports increasing the target amperage by 10A each 10s. However, no increased voltage reading is reported there, nor is there any increased current. ATTS:TGHT:RDCUR and ATTS:TGHT:RDVOL are ~0 as well. No increased temperature on any of 6 tc channels.

Wednesday, December 13, 2023, 11:57 ATTS TGHT power supplies appear to be under local control. It also appears (low current right now) that the value reported in EPICS is 1/3 of the value reported on the master power supply. It may be that the epics value is per output of the individual 3 supplies, while the total output is reported on the PS display. Planning to now increase to 300A and reach steady state.

Wednesday, December 13, 2023, 12:13 : 1/3 ratio idea confirmed at 33A EPICS reading / 100A master reading and again at 100A EPICS reading / 300A master reading. 300A now reached. Waiting for 20min. Temps inside ~ 21°C. Temps on feed through terminals ~22°C

Tuesday, December 04, 2012, 17:55 : vacuum at 3.3E-5 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

     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.

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

heating target for RFQ tests. Now the wiring is insulated with alumina beats and tubing and the target has the standard Ta alkali element mixture

Unfortunately I deleted some entries, so here a short summary in combination with a screenshot of the striptool

heated to 580A, vacuum increased over time from 4.8 to 5.6E-7T

HV up to 30kV - current of 37 uA - seems fine

Mass scan not possible, ops found a water leak in the magnet PS, optics around the magnet are thereofre also not available and red in EPICS

NOTE: all FC values are in reversed bias!!

done, source +4.5V, 2nd Rep&exit +12V:  RFQ offs =+12V, RFQ Ampl = 20V, 1 MHz (current 0.26A), locked up

there is something visible <~ 2E-12A at FC0

reduced current to 550A and leave it over night.

Short summary:

suppression possible but RFQ has to be shifted, the "only source shift" mode yielded a worse suppression than expected - unfortunately no mass scans have been possible, which would help to get some information on possible effects
