First P2N heating test ongoing.

At P2NHT ~ 570 A and TBHT ~ 100 A shine is already seen, which suggests that current is flowing in the P2N target properly, see picture attached.

Most of the ramping is carefully monitored because the good vacuum signal from the TTS ramping procedure is obviously not working (bypassed), and if the pressure goes past 1E-5T the whole ITS should interlock and abruptly drop the currents, which we want to avoid.

Wednesday, April 28, 2021, 23:16

P2NHT set current = 810 A

P2NHT read current = 800 A

Master and slave have balanced fully, TBHT ramping still proceeds manually. I'm trying to get it to ~200A before leaving.

 Thursday, April 29, 2021, 00:54

Ramping successfully achieved.

P2NHT_Master = 594 A - 4.59 V

P2NHT_Slave = 611 A - 4.89 V

P2NHT = 1207 A

TBHT = 231 A - 2.29 V

Max temperature of welding cables = 40 deg

Zero current from the HV ground terminal (feedthrough I) to slave negative (feedthrough H)

Beginning of May:

The cabling on the top of the test stand was changed to adapt for P2N testing. The TGHT and COIL PS were disconnected, and their DC cable terminals were connected instead to the TDK-LAMBDA P2Nheaters. The configuration on top of the ITS module is the following:

TBHT+ = A

TBHT- = B

MASTER+ = D

MASTER- = C

SLAVE+ = G/E

SLAVE- = F/H

Friday May 6th, afternoon

Once the pressure was almost stable in the low E-6 torr range, the first rampup was conducted up to ~600 A and the I,V parameters looked similar to previous P2N units. More tests to full current happening next week.

Monday, May 09, 2022, 09:29

P2N unit is being heated now, the automatic ramping utility is ramping the TDK-LAMBDAs while the TBHT is being increased manually.

Monday, May 09, 2022, 10:31

A voltage event happened, the TBHT voltage increased frmo 0.64 V to 0.73 V, while the P2Nheater dropped from  1.73 V to 1.56 V. 

Monday, May 09, 2022, 12:19

At P2NHT=950A it was noticed that one leg of the P2N was glowing much more than the other, the ramping was first stopped and then ramped down.

Now the P2NHT=282A and TBHT=47A

Tuesday, May 10, 2022, 09:32

Test stand vented and target inspected, there is no obvious sign of damage or misconnection on the tantalum assembly. Some resistance measurements were taken across target elements and connections: 

Screw on copper L to bottom flexy leg L = 117

Bottom flexy leg L to top flexy leg L = 24 / 0 (?)

top flexy leg L to bottom elephant leg L = 64

elephant L to elephant R = 360

top flexy leg R to bottom elephant leg R = 69

Screw on copper R to bottom flexy leg R = 125

Tuesday, May 10, 2022, 11:39

This morning, the target was inspected but nothing major was noticed, hence it was put back in the ITS for heating.

Tuesday, May 10, 2022, 17:40

Target being ramped: so far all good, total current in P2NHT=690A and TBHT=116A

A current measuring clamp was used to measure current in the 4/0 cables. The only bad thing is that the slave outputs half the current than the master, making the cables hotter (30deg vs 24deg).

Currents:

A-B ~116 A (TBHT)

C~468

E~124

G~102

Tuesday, May 10, 2022, 17:45

Event: reduction in P2NHT voltage and increase in TBHT voltage. After letting the PS ramp, it was noticed that the P2NHT voltage accelerated its increased, and the left leg started glowing like the previous time. The current was immediately ramped down, but still there was a voltage spike upwards in the P2NHT. 

While the leg was glowing hot, the current between feedthroughs H (P2NHT-) and I (HV common) was 90A. Now that the "episode" is not there any more, the current is zero

Wednesday, May 11, 2022, 10:55 

The previous P2N target had stainless steel screws at the bottom, where the copper L-shaped connector and the ta foil legs connect, which might have bene the cause of the gap opening and voltage increase. Now, the target manufactured for the previous beamtime is used, which does not have the cuts on the elephant ears but they are OK since don't interfere with the new IS cup design, and are ~3mm away from it.

Wednesday, May 11, 2022, 13:57 

 Start heating the new P2N assembly

Wednesday, May 11, 2022, 14:58

 Stopped at

P2NHT= 501 A

TBHT= 95 A

All currents seem to be flowing in the right path, with no current in the jumper between H-I

Wednesday, May 11, 2022, 15:26

Voltage step in P2NHT and TBHT happened again. Current sum:

A = 125 A

B = 125 A

C= 470 A

D=474 A

E = 118 A

F= 85 A

G = 95 A

H = 132 A

Short G-E = 5 A

Short F-H = 3 A

Jumper H-I = 62 A

The most likely explanation of this jump is that the IS tip touches the plasma electrode as shown in the drawing below which would result in some current flowing through the jumper, more investigations are needed

Thursday, May 12, 2022, 08:19

Test stand opened, there is some sign of burn in the plasma electrode, but it's hard to say if it's because they were touching. Aaron added a tantalum 0.040" shim to the plasma electrode to distance it further from the target IS tube

 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

Wednesday, May 26, 2021, 10:37 Target removed from test stand and brought to cold lab

Tuesday, July 16, 2019, 10:27: The idea of this run is to have the full 600 A from TGHT and the full 600 A from TBHT.

This will done based on the rewiring done previously (see entry 745)

Tuesday, July 16, 2019, 12:16: Jumper cable F-H burning while target was at 600 A total. Ramp up aborted and auto-cooling started to remove the jumper.
