Wednesday, September 24, 2014, 15:03, David Wang, South Hot-Cell, Standard Operation, TM4, Ta#44, Leak check on TM4 HS water line with new Ta#44 target. at SHC
|
This morning Chad and I leak checked TM4 HS line with new Ta#44 target installed. I calibrated LD before the check. Before check, the LD base LR 0.0xE-9 atm.cc/sec, base LP 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and did a flush around the target. There is no any response had been found on LD,. The line is good on leak tight. with spray method. No helium pressure test on the HS line at CS since TM4 was moved back to ITE directly. |

Wednesday, September 24, 2014, 15:16, David Wang, ITE, Standard Operation, TM4, Ta#44, Reconnected TM4 in ITE.
|
TM4 has been reconnected back to ITE. I started all turbo pumps on ITE and TM4. The ITE TP4s was extremely difficult to start. This pump is new, and was replaced before the last ITE beam time on July. After several times try and starting mode switch, it is started. Its temperature and current draw showed on controller and very good after the start. The current draw on ITE TP1s is s a little bit high and unstable. I will keep watching on ITE TP1s. I think the ITE TP1s is close to the end of the pump life. Other pumps are good so far. |

|
Ta#42 has been installed onto TM4. The "new" 9 pin connector was not an issue...attually went on better than any other previous one. Leaving the mounting screws loose on the target half allowed use of the manipulator to center the pins and insert them with ease. |
