Hey Joe and Matt, we are building the parts now and hope to ship by the end of the month, then the cavity will be rf tested, sent back to us, and then returned to jlab for brazing. We will do our best to not be the cause of any delays. I will give you updates as the parts come together. Thanks -Brock
Orders
  • Bellows - waiting on final count
  • Right angle valves - we have 5 or 6, should be ok?
  • Gun 10" flange - signed req for (2)

  • BPM feedthroughs - ordered
  • BPM cans - waiting on req to MDC
Controls
  • Chris, what cameras will you use, will they fit?
Joe Yes we will be replacing all the old tube style cameras in the injector, and replacing them with the standard assembly that we have implemented through out the main machine as well as the KeV region in the UITF.
