I used today's MD to improve mu-metal wraps in the 0L region between the booster and cryomodule. Mu-metal is there to reduce the earth's field by factor of 2-3 times over a long span where the beam energy is low. Still, bet if it's applied uniformly and concentrically with the beampipe. This is b/c the Earth's field doesn't disappear, it's just rerouted (div.B=0).

I doubt anyone will notice, but if a tiny bit of steering is required, this could be the reason.

ARC7 was locked out for work done under PTW-10105. Visual inspection of the magnet and shunt leads was performed and confirmed correct. Inside the shunt chassis, the cabling coincided with the connections checked downstairs. The shunt chassis for ARC7 was still the prime suspect and has been replaced. Channel addresses for the shunt channels and chassis jumpers have been changed and verified with the old chassis. Once the chassis was changed, the shunt chassis interlocks were again checked with the box supply under control power.

VBV1L11A - valve body was successfully swapped out. The old valve body had o-ring damage inside which caused air to come through the body of the valve. No air hissing on open or closed after completion of the work.
