Gun Test Stand Schedule
• Presently• Bunker and LAC are ready• Electrical installations and cabling completed• Solenoid field measurement completed
• Ongoing• Zoom optics resolution testing• The Holy Grail: UHV cleaned components should arrive this week (?)• Cabling of diagnostic module and connection to control system• EPICS drivers/software & optical link to hot deck
• Outlook• HV testing• Pumpdown and bakeout• Electron bombardment with a single-tip modified FEA• Commissioning & first measurements
