[chub, bob, gautam]

We took the heavy door off the EY chamber at ~930am.

Chamber work:

  • ETMY suspension cage was returned to its nominal position.
  • Unused hardware from the annular heater setup was removed.
  • The unused heater had its leads snipped close to the heater crimp point, and the exposed part of the bare wires was covered with Kapton tape (we should remove the source leads as well in air to avoid any accidental shorting)

Waiting for the table to level off now. Plan for later today / tomorrow is as follows:

  1. Lock the Y arm, recover good cavity alignment.
  2. Position parabolic heater such that clipping issue is resolved.
  3. Move optic to edge of table for FC cleaning
  4. Clean optic
  5. Return suspension cage to nominal position.
