GTS meeting 6 18 18

• GTS updated plan [1]

- Beamline magnets when Gun Solenoid at 400 Amps [2]

• Photocathodes activation with different Sb deposition time (5 mm limited area activation close to the center of GaAs substrate, with 25 A supply to Sb heater):

1. 30 minutes Sb deposition (heat cleaning again before second attempt, puck was too hot during activation)
2. 60 minutes Sb deposition (heat cleaned, to be activated today)
3. 90 minutes Sb deposition (completed)
4. 10 minutes Sb deposition (done, presented in IPAC'18)

• CST microwave studio simulations of 300 kV GTS gun: media:Gabriel_GTS_CST_18June2018.pdf
