Target/Number: Ta#48 
Subject: Helium pressure test on TM2 with new Lp Ta target 

LD base LR: 0.0 X E-9. Base pressure:0.0 X E-4. 70 psi helium. 5 minutes each circuit.

window 0.0X E-9  
HS 0.0X E-9  
EE 0.0X E-9  
Ta+ 0.0X E-9  
Ta- 0.0X E-9  
coil1 R-U 0.0X E-9  
Coil2 P-Q 5.0X E-9  
Tube- 5.1X E-9  
Tube+ 1.1X E-8  
MSP 3.5X E-9  

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits  comparing to before. 

The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time.
