| Step | Where can I find that? | Action | Details |
|---|---|---|---|
| 1 | Main panel | Switch on all 5 FELIX & Felice buttons | |
| 2 | wnd FELIX User Station | Select the correct user station | |
| Select 25 MHz or 1 GHz | |||
| 3 | wnd FELIX_dump_line_L2 | Find or Load a previous dump-line setting for E-range | |
| 4 | Find or Load the same setting in low-lever RF phases | ||
| 5 | wnd Magneetslingercircuit | Change current to match 2B20-25 | |
| 6 | wnd Gun > Felix | Change gun bias to ~170.5 V @ 25 MHz or ~80 V @ 1 GHz. | Precise number can be found in the file name |
| 7 | Check the file has correctly loaded in the HPRF window. Set values to match the yellow values | ||
| 8 | Main panel | Switch the “3GHz RF timing on†button on | |
| 9 | Set klystron modulators to target values (from file name). Step is ï¾4kV - 5kV. Press ‘feedback’ off, and ‘zero’. |
10. If FLARE solenoids are off, switch them on.
11. In low-level RF power boxes, press ‘feedback’ off, and ‘zero’ all.
12. Check timer S1 = 2µs and rep. rate = 1Hz. Open vacuum system.
13. Insert BS, and align cavity mirrors. Watch 2S21, align downstream. Watch 2S41, align upstream. Remove BS.
14. Press ‘GUN RF timing on’ on main panel.
15. Optimize e- path. Align with indicator. PM10 = SX10. PM20 = SX11. PM30 = SX30* (fault with blue, align 1 square below indicator). PM40 = SX40. PM50 = SX55. PM60 = SX70. Slowly ramp to ï¾10µs / 10Hz, ensure all e- are dumped.
16. Fine-tune low level RF phases. Once done, press ‘zero’, ‘load’, and ‘feedback on’ in all. At diagnostic station, switch amplifier to x1 (@1GHz) or x10 (@25MHz).
17. Adjust gun bias to achieve 360mV @25MHz / 200mV @1GHz (yellow curve on scope)
18. Find cavity zero. Set ‘dt_CLdetuning’ to zero, and adjust “DT_CLzero†close to an unstable state. Then, reset ‘dt_CLdetuning’ to 1.8.
19. Calibrate λ. Go to calc, and set lambda to correct live value.
