Lots of work on ETMX HEPI today. Because of the potential for HEPI pump glitches to feed into the BSC ISI's St1 T240s, we worked on installing position control on HEPI. These loops are now working and we have left the entire SEI platform (HEPI & ISI) in an isolating cofiguration. This does mean that commissioners will have to enter their offsets in a somewhat different manner, but Fabrice has explained it to Kiwamu. We have also attempted to put HEPI back in it's tilted state, it's not exactly where it was, but its pretty close. Monday, we will have to update safe.snaps for HEPI.
