 * CRY: Exchanging cryo valve during this week.

==== Night work ====

==== Weekend ====

==== Report of work ====
 * CRY: ITMX cryostat cooler and shield cooler were stopped yesterday. Outgas pressure was normal.
 * CRY: ITMY cryostat cooler was stopped yesterday. Outgas pressure was normal.
 * CRY: ETMY Shield cooler was stopped yesterday and there was a big increment of pressure. It means ETMY may have some contamination.

 * IOO: MZ was released from the main path of PSL.
 * IOO team is still woking on realignment after removing MZ. Unexpected large beam shift by removing BS happened.

 * Type Bp: Cleaned aroundf PR2.
 * Type Bp: Stepping motor did not work on PR suspensions GAS filter.
 * Type B, Bp: Checking for LVDT for PR2 SR2 and BS
 * Type B: It was found that loose cable connection on H3 coil for RM of SR2. It was fixed. 


 * DGS: We added BIO cards to k1lsc0. However it turned out that rebooting k1lsc always fails. Actually it was needed to shutdown to recover. V3 PC seems to have some problem.


 * DGS: Maintenance work for adding BIO cards.
 * DGS: Camera server maintenance. If you need camera, please use k1cam1.


==== Work plan ====
 * CRY: Repairing work for cooler valve will finish today. The last item is for ITMY shield cooler.
 * COM: Finesse will be done tonight or tomorrow morning, depending on progress of IOO work.
