  • Gun HV chamber
    • NEG cartridges have been mounted, but only 6 out of 8.
    • The perforated plate has been dry-fitted
    • The gun chamber has been baked at 250C with the NEG modules and the perforated screen only.
    • The NEGs were activated, first to 15 Amps while the chamber was at 250C, then a second time to 22 Amps while the chamber was back at room temperature.
    • The bake/activation cycle was performed to generate as much NEG dust as possible, which happens during the first two activation cycles per SAES paper.
