(Joe, Gerardo)
PSL light pipe and shutter were removed from the chamber side (HAM01), the main PSL beam vieport was exposed to apply FC on it. FC application (Joe used a small bottle) was finished by 4:10 PM yesterday, to protect the viewport we attached the old vieport adaptor with 3 screws to the viewport, and covered the 3" center hole with aluminum foil.
Work will continue today.

New MB PSL shutter is now installed.
Joe removed the FC sheet from the viewport and made sure it was clean, then the viewport adapter was installed on the viewport without problems.
Next to be installed was the shutter, the 3" nozzle has a very tight fit into the viewport adapter, it went in but we had to use longer screws to be able to press it in, then those longer bolts were removed and shorter ones were used instead.
The light pipe tube slid out of the other light pipe and into the shutter without problems, this was secured with two screws.
All items were cleaned prior to installation, including the PSL pipe, Sheila and Kiwamu pushed a wad of presoaked wipes thru it to clean it.
