T-shape Electrode Assemblies on R28 insulators in 15" diameter vacuum chamber
Ball Electrode Assemblies on R30 insulators in 18" diameter vacuum chamber
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
