3/19/21 - Bi-weekly meeting

Previous To-Do list from 2/12/21

• Marcy - select gold targets
• Jim - poly diamond sandwich design sketches (how mount to single crystal, metal)
• Marcy - any tech note on thickness, statistics, target and beam scans?
• Riad - send Euclid the tech notes on asymmetry as function of data rate?
• Andrei/Dave - could send Euclid the Hall A diamond data, also work w/Andrei on thermal after Euclid provides the ladder design (can do limiting case of all-radiative early)

Summary

• Responsibilities

JLab - Vacuum motion, stepper motor, transverse/vertical positioning

Euclid - Target ladder, targets, foils

• Diamond updates

(1) poly crystal plates arrived

(4) 3 karat 12 x 12 x 1.6 mm single crystal arrived => one cut into multiple 4 x 4 x 1.6mm

Can we use aerodag or HOPG

• Ladder updates

Agreed on length of 8 JLab positions, possibly shorter

JLab can provide chromox screen in adaptor and foils in adaptors

JLab & Euclid need to agree on Z offset position between vacuum shaft to scattering plane

• Calculations

Andrei will contact Dave to discuss starting thermal model and calculations

JLab needs to provide Andrei details on Mott acceptance for radiative cross-section calculations

• Students

Potentially a student from Turkey will join in Sep/21 during 2-year Master's program, option during Phase 2

JLab/Andrei continuing to look for a student during Phase 1 - at least during the summer month's
