Mike V, Rick S, Darkhan T

This morning Rick and Mike went into chamber to continue with the alignment of the PCal transmitter and periscope, with Darkhan outside. Alignment now looks good.

This afternoon we will continue with alignment checks of the camera mirrors.

Particle counts were reasonable before work commenced (attached photo IMG_0086), however after exiting chamber counts were very high (attached photo IMG_0087).

This is most likely due to stirring up dust; we will wipe the floors as well as the PCal periscope and Manifold Cryo Baffle which are noticeably dirty.

Some odd noises were also coming from the clean air compressor (very low audible tone), Kyle is investigating.
