TM1 full leak check in conditioning station has been fulfilled this morning.Both air to vacuum leak check and waterlines helium 80psi pressure test are fine.The result:

Air to vacuum helium spray:base leak rate on leak detector 1.6x E-9 atm .cc/sec.base pressure0.0xE-4 torr. sprayed helium around all flanges, turbo pumps,panels,bellow,insulation stands, gauges. No Response on leak detector. Air to vacuum seals on TM1 is leak tight.

Helium pressure test on all water lines.with 80 psi helium 3minutes test:

        PNG1 :2.4XE-7torr .PNG4 :2.6x E-6torr . IG1 :5.1xE-7torr.

A :target oven(+)  BL:2.0xE-9 atm.cc/sec .First minute no response,then climbed to1.9xE-8 atm.cc/sec. Stabled at 1.9xE-8 atm.cc/sec to 3 minutes.

B:target oven(-)    BL:5.5x E-9 atm.cc/sec.First 80 seconds no response, then climbed to 1.8xE-8atm.cc/sec. Stabled at 1.8xE-8atm.cc/sec to 3 minutes.

C:tube heater(-)   BL:8.0xE-9 atm.cc/sec .First minute no response ,then climbed to 2.7xE-8 atm.cc/sec. Stabled at 2.7x E-8 atm.cc /sec to 3 minutes.

D: tube heater(+) BL: 1.0xE-8 atm.cc/sec. First minute no response , then climbed to 1.8xE-8 atm.cc/sec. Stabled at 1.8x E-8 atm.cc/sec to 3minutes.

G:EE  BL:1.0xE-8 atm.cc/sec .First 1.5 minutes no response , then climbed to 1.7x E-8 atm.cc/sec. Stabled at 1.7x E-8atm.cc/sec to 3minutes.

F:heat shield   BL:1.2x E-8 atm.cc/sec. First  1.5 minutes no response , then climbed to 1.9 xE-8 atm.cc/sec. Stabled at 1.9 xE-8 atm.cc/sec to 4 minutes. Total test time 4 minutes.

I: mounting plate    BL:1.2 x E-8 atm.cc/sec.     NO RESPONSE on leak detector  in 3minutes.

M: window   BL:1.2x E-8 atm.cc/sec First 1.5 minutes  no response,then climbed to 2.0xE-8 atm.cc/sec . Stabled at 2.0xE-8 atm.cc/sec to 3minutes.

The base pressure on leak detector stayed at 0.0x E-9 torr through all the test, and no pressure response on high vacuum gauges.
