Tuesday, February 09, 2021, 13:43: DI water flow completely stopped.

Control room contacted. DI water loss confirmed.

Tuesday, February 09, 2021, 13:52: DI water flow returned.

Control room contacted. DI water loss due to a "seamless" pump change over for the DI water supply & mechanical services. The supply was transferred over to a new pump which overloaded and failed. They had to switch back over to the (old) pump. Mechanical services will still try to do the switch over again. Either tomorrow or the day after. Running the TS up to 580A until then is not recommended.  Control room to update tomorrow morning.

Fault# 13773: Cu-LCW south SA3-03 tripped on motor overload.

 Friday, February 12, 2021, 12:13: Since the collimator is not used, Carla and I installed a BNC short outside the cage. See picture.

Friday, February 12, 2021, 16:37: FEBIAD installed with mechanical calibrated leak

Friday, February 12, 2021, 16:38: Roughing.

Gas lines opened all the way to the sour. SV4 and SV5.

Friday, February 12, 2021, 18:47: Turbos on.

Friday, February 12, 2021, 18:55: IG1 on.

Friday, February 12, 2021, 23:22: IG1 @ 1.5E-4 T.  I think the line inside the vacuum chamber is leaking

Friday, February 12, 2021, 23:23: SV5 closed.

Friday, February 12, 2021, 23:24: Vacuum dropping slightly.

Friday, February 12, 2021, 23:24: SV5 opened. IG1 responds to the opening of SV5. The lines from the feedthrough to the calibrated leak need to be re-done.

Tuesday, February 16, 2021, 10:21: IG1 off. Turbos off.

Tuesday, February 16, 2021, 11:21: Venting.

Aaron closed SV4 and the vacuum drop normally. Leak through SV5 as well.

Vacuum side

Tuesday, February 16, 2021, 13:42: The gas lines inside have been check. The inlet of the calibrated leak was not tighten properly and hence the large leak observed.  FIXED.

Tuesday, February 16, 2021, 13:42: The only leak remaining INSIDE the vacuum is the one on the FT side which for 200kPa is around 7e-6 atm cc /s. At this pressure, the undesired leak  is leak rate is around 1 %  of the one getting into the source.

Atmosphere side

Tuesday, February 16, 2021, 14:49: Some minor leaks in connection points around  1e-6 atm cc/s. Not much I can do without changing all connection to glands with metal gaskets.

Tuesday, February 16, 2021, 14:50: SV5 was leak check on its own, the gas goes through quite noticeable, no need to sniff with leak detector. SV1 leak checked and it works.

Tuesday, February 16, 2021, 14:52: Valves swapped, labels changed.

Tuesday, February 16, 2021, 15:17: Roughing.

Tuesday, February 16, 2021, 15:53: Turbos on.

Tuesday, February 16, 2021, 16:53: IG1 @ 2.9e-5 T.

Wednesday, February 17, 2021, 16:53: IG1 @ 1.5e-6 T.

Wednesday, February 17, 2021, 16:53:  The Neon bottle seems to be empty. The leak on the lines were not as bad to have this happened. I suspect when squeezing the bottle I rotated the gauge enough to cause a leak there.

Wednesday, February 17, 2021, 17:00: Using a full nitrogen bottle, I confirmed that rotating the two-stage regulator causes a leak.

Wednesday, February 17, 2021, 18:00: Things look OK now. Water open. No response on vacuum. Will put power.

Wednesday, February 17, 2021, 20:00: Some items were timed out. Tried to recycle the PLC now all the items are red. Check tomorrow

Thursday, February 18, 2021, 10:45: TPS:Q3 & the TSB CBC CANBUS controllers had failed yesterday, as well as a cable was incorrectly seated. This was fixed this morning.

There was a previous DI CU-LCW  pump trip as per the above elog. The CU-LCW pump was configured this morning. The water pressure is set to 80 PSI as per the MCR. Any further can overload & trip the pump. 

Thursday, February 18, 2021, 10:55: Current flow rates & pressure read at the TS

DI water pressure as per the gauge on the supply side of the FS#2-5 manifold @ 85 PSI.

Noticeable flow rate reduction based on previous target conditioning logs. Previous pressure was around 100 PSI.

Thursday, February 18, 2021, 15:01: With the help of Spencer Kiy, we tested the proper communication from python to epics.

Getting TSP:Q1 PV: successful both from the web application and jupyter notebook.

Setting TSP:Q1 PV: successful from the web application, failed jupyter notebook.

Issue fixed on the HLA server side

Setting TSP:Q1 PV: successful both from the web application and jupyter notebook.

Testing other potentially useful apps for ramping routines and a  customized "striptool".

HLA developments only available from the ISAC test stand's PC and Fernando's PC.

Thursday, February 18, 2021, 15:19: Gas lines roughed and refilled. Gauge reads -50 kPa. Absolute pressure is 50 kPa.

IG1 @ 9.7 e-7 T.

Thursday, February 18, 2021, 15:27: BIAS/EZL/EE @ 30/13/1.5 kV. No sign of instabilities as before. Bias current=0.08 mA.

This also means the leak, in this clean environment is fine.

Thursday, February 18, 2021, 15:28

Slightly drop in flow. Will check later as well.

Thursday, February 18, 2021, 15:37: BIAS/EZL/EE @ 35/13/1.5 kV.

Thursday, February 18, 2021, 15:39. Spark inside. Recover with no problem

Thursday, February 18, 2021, 17:26: Anode is shorted. It seems that the  Ta capillary  is touching the HS. I have to open.

Thursday, February 18, 2021, 17:35: IG1 and turbos off.

 Thursday, February 18, 2021, 18:2: Venting

Thursday, February 18, 2021, 18:42: Gauge reader at the service cap is now at -40 kPa. A 10 kPa incursion over 4 hours.

Friday, February 19, 2021, 11:04: The anode still has a short, returning all previous jumpers. Short present.

Unhooked anode cable can sustain voltage, hence the electric circuit has a short,

Friday, February 19, 2021, 11:48: Target removed. No short on anode-target. However there is no short in the service tray either, the voltage from the anode supply is held with no problem.

Friday, February 19, 2021, 12:41: Only when the tbht is bolted the power supply goes current limited.

Friday, February 19, 2021, 12:44: Source tray can hold anode voltage without drawing any current, as expected.

Friday, February 19, 2021, 12:52: Target legs to HS presents a short. When HS is removed the short is gone. Will try to find the contact point.

Friday, February 19, 2021, 12:56: Suspecting that is the gas line that goes to the back of the TGHT; is too high and touches the HS. Putting and insulator and installing the HS cover. No short.

Removing the insulator there is a short.

Will bend the gas line.

Friday, February 19, 2021, 13:08: Installed the open assembly, and the anode voltage is held in the system without drawing current, as expected.

Friday, February 19, 2021, 13:21: TIS assy re-installed, short is fixed.

Will wait until vacuum is stable to try  to put high voltage.

Sunday, February 21, 2021, 21:51: IG1 @ 2.06e-6 T.  Unable to go above 5 kV.  

Sunday, February 21, 2021, 22:00:  Auto-cooling TGHT/TBHT to 0 A @ 2 A/min 

Monday, February 22, 2021, 09:12: IG1@1.01e-7 T. Bias gets current limited as of 11 kV. The system does not spark so the current is leaking through somewhere.

Monday, February 22, 2021, 09:29: Grounding the TM2 F/T. No effects, same bias issues.

 Monday, February 22, 2021, 11:3: the only way for this instabilities to occur is with a short between ground and HV. No such touch is occurring inside.

Monday, February 22, 2021, 11:37: Instability reacts with punching the cage, that is, shaking up the cage causes the instability to decrease.

Will re-accommodate the cage as it seemed slightly crooked, hence the motivation to punch it.

Monday, February 22, 2021, 14:00: Cage re-accommodated with the help of Aaron. Move a insulating cable that was touching a FT.

Monday, February 22, 2021, 14:30: Now sparks are visible between the coil/HS waterlines and ground waterlines (see pictures attached). I have to open the vacuum chamber.

Tuesday, March 16, 2021, 15:04  Mike is finished with emittance meter controls so ramping everything back up and trying to get beam through.

Thursday, March 18, 2021, 18:06 : Vacuum has been rising slowly over the past 20hrs from 9.3e-7 to 9.9e-7. Everything has been up since Tuesday. No beam through emittance meter, though beam can be found on the regular test stand emittance meter. Just discovered that both voltage plates are plugged into positive power supplies so waiting for a controls fix on that then will retry.

Friday, March 19, 2021, 17:08 : Finally success. New emittance meter shows same results as the standard test stand emittance rig. Will continue testing new controls next week

Vented beamline and removed ARIEL emittance meter. In the process of swapping components, beamline left vented until Monday when we will finish the job.

Emittance meter number 2 ready for beam shortly - installed and pumping down.

No beam found by Thursday evening, but beam seems to be coming out much differently than last time. Will check on emittance meter functionality and try to re-tune later.

Ramping things down for the next couple days.

Saturday, April 03, 2021, 10:41 :

Source heating ramped back up, everything back on. Will try to straighten out steering then see if I can get things back in the previous positions.

Saturday, April 03, 2021, 14:59 :

Nothing seems to be working, will vent the beamline and remove the slit.

Saturday, April 03, 2021, 15:36 :

Apparently closing the valve started a vacuum leak that tripped everything in the source. I noticed within the first minute and ramped everything back up, maybe too quickly....

Have now put everything in a holding state, will resume tomorrow.

Sunday, April 04, 2021, 14:17 :

Found everything off again this morning. Ramping back up in the hopes that I can get something done before the whole system trips again. The trips look like water leaks again.

Uninstalled the slit and left it in the bottom of the vacuum box. Swapped the window to the computer side for convenience. Seal on the other side on the CF flange is a bit weird, not sure if it is in properly...

Sunday, April 04, 2021, 18:43

Still no beam. TISA emittance FC won't come back on, so waiting for Mike Rowe to troubleshoot on Tuesday. Will ramp things down all the way, since I expect the vacuum to trip the source before I need it again.

Tuesday, April 06, 2021, 23:43

Found some beam, but looks really weird, like it is cut off. Good enough. Ramped everything down.

IG1 has been spiking randomly, causing everything to turn off. Looks like the water leak is still there.
