Update on status - 11th of June 2009

The current status of the system is that we are preparing for the first RF processing procedure to train the copper cavity. A few systems have to be put into operational before we can start, such as cavity temperature control, vacuum control and RF power control.

Last year we have had many setback, such as vacuum leaks to do cracks in the soldering. All have been repared and since the end of the summer 2008 the cavity has been installed into its stainless steel container. After that, a vacuum backout session has been conducted to clean the cavity.

In September 2009 we also finished a demonstration version of the RF cavity made out of brass that has been caoted by gold. I have added a few pictures.

Side view of the RF cavity. On the left is the cathode surface and on the right the coaxial incoupling of RF power that is also the electron beam exit.

On this side you can clearly see the springs that clamp the cavity cells together and press it on the RF in coupler. You can also see the cooling channels and the thermocouples to measure the internal temperature.

On this side you can see the coaxial structure. The RF in coupler or mode transformer is connected to the cavity on this side.
