Helium pressure 70 psi. 3 minutes on each circle untill LR on LD is balanced. Base leak rate on LD:0.0xE-9 atm.cc/sec.   The result:

A:   slowly to1.8Xe-8atm.cc/sec after 2 minutes and balanced there. 

B:   slowly to 2.0XE-8 atm.cc/sec after 2 minutes and balanced there.

C:  quickly response  to 3.1XE-8 atm.cc/sec and balance there.

D : slowly to 3.0X E-9 atm.cc/sec and balanced there.

All others including coil1, coil 2 ,MSP, EE, HS, window are perfectly leak tight. No response on LD.

 The leak rate on A,B,C,D are in low E-8 or E-9 atm.cc/sec range.  They should seal cooling water without leak.    No concern.
