    keyword=Right arm dipole NMR problem

    Right arm dipole NMR information was missing from start of run files. We confirmed that the right arm field/momentum values were not updating, and confirmed that the NMR screen was dead (by trying to switch the units from Tesla to MHz, as per log entry 186341). Reset via hareboot27, port 8, which destroyed the NMR lock (on the scope), but it did not respond afterwards. Rebooted iocha16, and then the dipole NMR again, and things were responding. However, there were several problems with the dipole:

    The NMR would not lock. Eventually realized that field pol was set to pos (instead of neg). Changing to neg. manually led to the NMR sucessfully locking

    Changing the HRS-R momentum had no effect on the dipole, and trying to set the current manually also had no effect. However, in both cases, the NMR screen set the polarity back to positive.

    Tech is on his way in now... :(
