The following in vacuum cabling was added to ETMx for the Electric Field Meter (EFM). While the EFM is not the final version the cabling installed is the final version.

We added LIGO-D1800089-v2  SN S1800629 and LIGO-D1800090-v1  SN S1800631.

With reference to page 11 of the LHO ETMx in vacuum cable routing drawing, LIGO-D1300007-v2 , these above additions were placed in the existing ISC-QPD (532 NM) path.

It should be noted that a 15-pin cable bracket, LIGO-D1800072-v1 was also added between the 15 pin sections. However, the wrong base was sourced for the required cable bracket, LIGO-D1001347-v3, between the new LIGO-D1800090-v1 and the existing D1000924. So this is pending. Either a new based has to be sourced or 3 cable portion replaces the existing 2 cable portion of D1001347 on the table.

We will update the required SYS drawings to match this (and ICS).
