Joe D, Cheryl, Rodica

With the most invaluable help from Joe D we got the TGG crystals completely restored to their shine yesterday. With the crystals in their holders we flushed freon inside the tubes and perfectly removed all contamination.

Cheryl and I reassembled the Quartz crystal with new strips of indium foil and closed the second assembly for the single TGG crystal and brought everything back inside the PSL enclosure.

We also cleaned the inside of the dust shield of the magnet with vectra alpha wipes and IPA.
