"beam" spot on the scope in middle room CH where we monitor the raster size??? there is a dot on the scope, which very much looks like an unrastered beam. we came back after about 4 hrs of power down throughout the accelerator site, so it is fairly unlikely that the beam is still on. most of the iocs are down, and i cant get any meaningful information from any of the NewTools guis. the target in place is Dummy Al. the spot is most likely due to current sensor readback problems or scope readback problems (hopefully)
