Clara Presentation:

• using 3D of 4Dphoton design, old magnet from D. Bodart and see if we can fit in and made a conceptual design
• Swan thesis - found some details
• Uncertainty <5% in profile error (IPM, CST)
• Goals and considerations
• 1st design concept with L shape top chamber for HV feedthrough (slide 7), hard to imagine how to attach HV to cathode.
• IPM simulations by Clara, CF250 flange seems good based on the error and size tradeoff
• Likely need to increase gap of magnet opening by at least 20mm
• Few conceptual design sketches drawn up to address on how the chamber layout and how the HV feedthrough will go in.
• Some more ideas came up (30 degree angle feedthrough etc).
• Suggestion on welding the HV feedthrough directly on the flange instead of connecting through a CF40 flange
