Dave Gaskell called. The power supply for the 2 cm vertical chicane at the end of the line, MBE3H05, had a water leak and will take a long time to dry out. The power supply for MQF3M01 is the same type and the leads can be moved over. Prior to March 2021 MQF3M01 was not part of the transport optics. I found my file from March 2020 and scaled the end of the line to 10678 MeV. The changes were placed in special file C10678_no3M01.snap.
