At today's meeting we heard about the following:
Tally of ME jobs
- ground screen - open wire mesh w/ frame + connectors to tabs
- anode design - flat & tilted grounded tube + slots for increased conductance
- model field - symmetric model fields for electrostatic solution
- assembly dwg - complete set of drawings and parts
- layouts - CEBAF integrated with Phase 1 beam line + UITF modifications to test temporarily
Cathode
- Ceramic welded to vacuum fired flange ready, verify if leak checked
- Weld spare ceramic to vacuum fired flange, leak check
- Cathode ball and Pierce electrode ready, polished
- Cathode "butt" in hand, needs to be polished
- Cathode puck holder parts mainly in hand, need sapphire roller hardware (instead of welding wire)
- Carlos will tally plan for polishing, cleaning, fit-up, assembly, and fiducials
Anode
- Anode - proud + maintain 6cm gap
- Support tube - grounded + flat & tilted + Gabriel will try electrostatic model with slots Marcy recommends for conductance
- Spider - use existing
Vacuum Chamber
- Fiducials welded
- Marcy blow off new NEGs, install w/o ground screen, add NEG wiring, gauge, blank and bake
