FYI: I'm currently installing some new gas bubblers in the left shield hut for the VDC and FPP. I will have the gas system and VDC HV, for this arm, turn off until approximately Tuesday (Jan 17) for this installation. Anyone needing to conduct work that requires operating either of these systems should contact myself or Jack Segal prior to changing any HV or gas flow settings. Once the work has been completed I will enter a follow-up log entry to notify all pensonnel. Thanks.
