Analog Camera swapped to Gige Digital Camera on ISCT1. MLC Mirror and in-air POP-X WFS Removed.

Fil, Keita, Daniel, Camilla  WP12598 WP12584

We swapped the old REFL Analog Camera to a Gige Digital Camera (Basler acA720-290g m S/N 40477593) on ISCT1 and cabled to the table feedthrough. There was no beams today so the alignment may need to be touched up.

Keita and Daniel also removed the MCL steering mirror, controller and the in-air POP-X WFS (S1300511, now stored in the EE shop) with mirror and lens from ISCT1. MLC controller and PZT will be stored in mid station storage. The beamsplitter towards the old POP-X path stayed but was blocked with the beam dump that used to be dumping the POP-X reflection.

Complete MCL PZT/controller inventory at LHO

Note 1: Each Mad City Labs PZT is supposed to be paired with a matching controller. Their manufacturer's serial number starts with MCLS (PZT) or MCLC (controller) but share the same number (e.g. MCLS02218 and MCLC02218). In the table below I only wrote down the number part.

Note 2: Each PZT and controller originally came in two separate boxes. These boxes for the units that are in use (or was at some point in time) weren't found in the MY storage except for one EX green WFS PZT/controller and another pair for EY.

Note 3: The PZT assembly for the old in-air POP-X that we pulled comprises the PZT, ALS Mad-City Labs base (D1300607), Mad-City Labs spacer (D1300608), Modified UPA1 holder (D1300124), and 1064nm HR 1" mirror. See 1st attachment.

Location Purpose S/N Notes Boxes?
EX Green inj 02218 alog 8080 Not found
02720

These replaced the high power unit (MCLC02219, the last row of this table), which was "to be replaced". alog 8080
Haven't checked if the PZT is MCLS02720 or 02219, but it's probably 02720.

Pulled from ISCT1 in Jun/2025. Used to be for old in-air POP-X. Mid shelf (1st/3rd pic).

PZT is stored as an assembly with ALS Mad-City Labs base (D1300607), Mad-City Labs spacer (D1300608), Modified UPA1 holder (D1300124), and 1064nm HR 1" mirror in a gray plastic bin, on which the controller is directly placed.

Spare of spare MCLC02219

Top shelf (3rd pic). Controller only (no PZT was found), high-power version (Nano-Drive 85), old EX unit which was replaced. alog 8080

This is 2U-high, accepts 110V AC rather than LIGO 3-pin DC and looks different from the rest of the controllers.

No box
