Neutron dose due to field emission is constant throughout, as seen when there is no beam (flat and quiet spots).   The difference with beam loss in the recent NL sum is 54 Rem/hr as indicated.    Around 1300 the difference was 13 Rem/hr, figure 2.   There were two long periods of Hall A tune beam in parallel with Hall C CW from 1700 to 1900, the regions where the noisy blue trace (BLA loss) at the bottom went up artificially.    I don't know what changed but we need to find it.  Concentrated at 1L22, 1L23, 1L24 in upper pane; later NDX signals up only a little absolute.
