Main Goal
The Nov/2018 T539+T545 session had reduced beam time due to one primary LCLS experiment didn't permit the 5 Hz parasitic beam to ESTB. A makeup shared session was negotiated during this period with T577 (Moller calorimeter) also using secondary beam. The main goals of this test session:
...
2) An independent examination of the L1A time distribution with the SLAC HSIO2+FEB readout. Data taken so far with YARR all exhibited a very broad distribution.
Preparation
Caladium was moved into place at the start of T577 and remote driven to far wall with 1-2 inch clearance from beam line so that we can remote drive it back to beam line.
A97 had 1000e tuning from Timon on YARR during last period. Checked with RCE+FEB calibration looking OK
| A97 | Thresholds | Noise map |

| HSIO2+FEB |
B53 had brief tests by Aleksandra before sent to SLAC
