Drawings and Field Maps

Drawings

• Updated CEBAF Injector Drawing and Dimensions in SI Units -Latest update 08/20/2020: Added E- and B-Field layout with positions, lengths, and apertures.
• Josh's CEBAF layout w/ some extra details (11/15/19) - media:191115_layout.pptx
• CEBAF Injector Drawing and Dimensions - to VWF entrance

CEBAF Gun

Cathode bias: -130kV

Anode bias: 0V

E-Field & Potential Map Dimensions (in meters): -0.030<=x<=0.030, -0.030<=y<=0.030, 0<=z<=0.935, stepsize=0.001, z=0 denotes the front face of the photocathode

Note that at z=0.935, V is on the order of 10^-18V, so I have not gone past this.
