==== Report of work ====
 * !st Engineering run was successfully finished.
  * Lock lost was only 3 times after fixing trouble on PR3.
  * Duty cycle was more than 95%.
  * PR3 had some glitch or bistable on TM pitch for few urad, probably due to the temperature change around PR area.

 * DRMI lock was established ~1min. Oscillation introduced fringe jumps and lock was lost.
 * Y arm lock was tried also.
 * To check alignment of REFL table.



==== Work plan ====
 * Continuously fixing ITMY issue.
 * CAL: Measurement TF coil driver for ETMs.
 * IO chassis of EY0 will be exchanged.
