ELECTRODES

• T-shape electrode with pure alumina (white) R28 insulator and 6.3 cm anode-cathode gap. Tested and beam run at 200keV in test cave, later operated in CEBAF injector for many years
• 
• Modified T-shape electrode with triple junction shield (Mushroom) on doped (black) R28 insulator and keeping 6.3 cm anode-cathode gap
• 
• Spherical electrode on R30 insulator with 6.3 cm anode-cathode gap
•
