We noticed water and/or condensation in the instrument air lines in the GTS - we used the air to blow dry our lines in the room, but there may be water in other lines that needs attention. Pull down menus weren't very clear where I should tag this - this in in the LERF gun test stand.

Cav. 1 seems better, cav. 2 processed one emitter and opened another - may be worse. 1L23 is on now for AES-RF work. Turning decarad off and deferring further work until later - can't see a clean FE signal right now.

If ops is bored tonight, FE measurements can be executed on those 2 cavities - but it can wait for later too when more processing has been done...

We finished all ZA dipole work and the repair worked just as planned. S/A also completed final checks and will pass along data when able. ZA passed Hi-pot after all work was completed.

Thanks to everyone that helped, huge team winning effort.

DC power can hookup dipole and complete testing when they are ready.
