** The QE was estimated to be around 0.3%<br />
** We discovered that the Haimson coil corrector was not steering the beam properly. Later on Joe Grames and Yan Wang discovered it was wired up as a quad. They corrected the problem.<br />
* [https://logbooks.jlab.org/entry/3411250 Beam on Viewers]<br />
** Adriana and Shukui did a calibration of the laser power meter located inside the hutch and read in the control room with respect to the laser power going into the gun vacuum chamber.<br />
* [https://logbooks.jlab.org/entry/3411281 Did the cathode got damaged here?]<br />
* [https://logbooks.jlab.org/entry/3411348 Image of cathode damage]<br />
* [https://logbooks.jlab.org/entry/3411358 Laser and electron beam after discovering bad laser shape]<br />
** Adriana discovered that the bad laser shape is due to a damaged polarizer in the hutch. Shukui gave permission to fix the problem. <br />
