I started TCS water system.

TCS vacuum system and water system have been started as well. Everything looks fine.

  ITW turbo pumps  have been started.

All turbo pumps are started. Two gas valves for Febiad run are opened. Pumping down is good so far.

TM2 has been connected in ITW. During the connection, Anders and I  found the TM2  high current cables used in ITE and CS are short in ITW.  Anders and Grant found the original TM2 ITE high current cables in target hall. We replaced them. They works fine. But, a little bit longer on cable length would be easy to connect them. All other connections and HV cover in ITW work for the TM2 so far.

Chad and I finished the first round check on Tm2 water lines. The lines and spots checked are: Target oven + and - (front side braze joints) , Tube heater+and -(front side braze joints and water blocks), coil2 and coil 1(front side braze joints and area close to water blocks),. No leak has been found on all above of them.  The last, we checked   the GE which has the biggest leak so far. The leak detector base leak rate only can get to 4XE-9 atm.cc/sec. Chad sprayed helium very close to GE water block, and I got a quick response on leak detector. The leak rate climbed from 4Xe-9 atm.cc/sec to 1.4 atm.cc/sec. We confirmed the GE is leaking now. The exact location need to be pinpointed later once the containment box is out after the module is back to SHC. The module will be moved to TCS tomorrow morning and pressurized again there. Anders will use RGA to monitor the helium response during the check.  

Ramped voltage on TM2 up to 30kV with no problems. Bias current is at 29uA, same as original TM2 bias current (see archiver for ITE June 15th, before protons) and similar to 31uA right after protons went off on Aug. 6.

TGHT=0A

TBHT=0A

BIAS V=30kV

BIAS current = 29uA

EZL V= 15kV

EZL current= 51uA

EE V= 1kV

EE current= 0.952mA

IG1= 8.6e-7

protons=0

This seems ok despite poor electrical checks showing 300 MOhm resistance between HV and ground. These values indicate a resistance of 1 GOhm. Let's see what happens when protons are on.

For future (optimistic) reference when testing protons:

BIAS=35kV, 35uA

EZL-17.5kV, 60uA

BIAS=38kV, 37uA

EZL=18.5kV, 63uA

 An electric check was done right after module moving from SMP to SHC. 

 TM2 with no target on SW silo be electrical checked right after module moving.

 A standard electrical check was done for TM2 after the short issue be fixed.

I did electrical check before and after Fefiad target installation on TM2. The RU (coil) Is till short to 60KV as before. Other result are good. After Febiad target is installed, Tm2 HS line is leak checked. On leak detector, base leak rate pumping down is much slow  than before.  The base pressure still could be pumped down to 0.0XE-4 torr.  After a long time wait, Chad and I leak checked at 2.2XE-8 atm.cc/sec base leak rate. Chad sprayed lots helium around the fittings and target. No any response has been found on LD. At this leak rate, the target and HS line is leak tight.  The Tm2 has been moved to THC so a heium pressure check will be fulfilled on HS line at TCS to confirm this leak check result.  

TM2 HS line is pressurized with 70 psi helium at TCS. LD base leak rate: 0.0 X E-9 atm.cc/sec. Base pressure 0.0XE-4 torr. 5 minutes test time. The leak rate slowly climed to 3.3XE-9 atm.cc/sec and stabled there( 3minutes). base pressure no change. The leak is too small to be concern. We will run this target as this condition.

TM2 electrical check and leak check are done at SHC with C#2 target installed. The results are good.  

Containment box was removed from Tm2 this morning  in preparation for installation of coil line and all the trimmings.

Tm2 containment box has been re-installed onto TM2.

TM2 containment box has been removed. Found a piece of capton tape or tubing under table (see picture).

Chad installed containment box back to TM2 yesterday. We leak checked VCR joints on window line.    No leak.

The containment box has been reinstalled onto TM2 in prepatation for testing in the conditioning station.

TM2 was connected yesterday by Frank and Anders. The West side panel with IG1S on Exit Module 2 was replaced with a new SST panel with 1 CF flange only (dwg). Link to check list on DocuShare.

TM2 has been moved to TCS and under good vacuum. TP1/2 work fine.  Electrical check: A to PQ still dead short. B to C @250V 3.8M which is ok still . We knew these two things before. Other things are good. Vacuum: air to vacuum seals on TM2 service cap are good. Helium pressure test on all water lines are good. HS line no target so can't be tested. But We did helium pressure test on each target change so it's fine.

TM2 has been moved to CS. All turbo-pumps have been started. The pumping down is good so far.  I connected the leak detector to service cap, and finished the leak check today.  The LD base LR:0.0Xe-9atm.cc/sec. 80psi helium were applied to coil1, coil 2. HS and window circuits, each for 2minutes. No any response has been found on LD. So all water lines are leak tight now. I also sprayed   helium to top service cap checking all air to   vacuum seals. They are all good either. But, The new installed PGN1 does not work. Other thing need to mention is The TP2 is running at 2.45A which is 1A higher comparing to TP1. It need to be monitored to see if we have to replace it or not. The high current cables and water lines will be connected tomorrow morning.
