Joe
- What are ceramic break dimensions? - We have ceramic breaks in EEL-118. Here are two options: a "long" one which is 4-1/4" overall length and a "short" one which is 2-9/16" overall length. Both have 2-3/4" end flanges; one is rotatable and one is not.
- "What are the as-found PEPPo Faraday cup dimensions?" - The assembly is stored in EEL-117 shown in the photo below. The 6-way cross includes both 4-1/2" and 4-5/8" flanges. Details of the assembly are shown in the assembly drawing below. The faraday cup assembly, viewer assembly, optical port to see view screen as installed and the thin beam exit Al window remained attached since the experiment and should be "vacuum ready". The ports for beam entrance and ion pump were the only vacuum disconnects made thus far and are blanked off.
