2 Outline ISAC-I RF system names ISAC-I RF amplifiers locations ISAC-I RF control stations locations How to turn on amplifiers How to turn on rf Troubleshooting & system rebooting

3 ISAC-I ACCELERATOR

4 ISAC-I RF Device Names LEBT RF -- Pre-buncher(11/23/35Mhz), RFQ (35 Mhz) MEBT RF -- Bunch Rotator(106Mhz), Chopper 5, Chopper11 & Mebt Rebuncher(35 Mhz) DTL RF -- Tank#1 (T1), Buncher#1 (B1), T2, B3, T3, B3, T4 & T5 (106 Mhz) HEBT RF -- Hebt 11 Mhz Buncher & Hebt 35 Mhz Buncher DSB RF -- DSB-buncher (35 Mhz)

5 16 Amplifiers (5 SS, 11 tubes PAs) LEBT RF (2) -- Pre-buncher (Solid state broad band PA, 500W), RFQ (4CW150,000 Tetrode, 85kW cw, 150kW pulse) MEBT RF (4) -- Bunch Rotator (3CX3000A7 tube at 3.0kW), Chopper 5, Chopper11 (SS 45W/140W PAs) & MEBT Rebuncher (SS 1.6kW PA) DTL RF (8) -- Tank#1 (T1), Buncher#1 (B1), T2, B3, T3, B3, T4 & T5 (4CW25,000 tubes, 4 ~ 25 kW) HEBT RF (2) -- HEBT 11 Buncher (SS 2 kW PA), HEBT 35 Buncher (4CW30,000 Tetrode, 13kW) DSB RF (4CW25,000 tube, 13 kW)

6 ISAC-I RF Amplifiers Locations Bunch Rotator, Chop5 &Chop11 Pre-Buncher & RFQ Mebt Rebuncher, Hebt 11 DTL, Hebt 35

7 ISAC-I RF Control Station Locations Four control stations to control 16 amplifiers Station#1 : Bunch Rotator, Chopper5 & Chopper11 (3) Station#3 : MEBT Rebuncher; DTL T1, B1, T2, B2, T3 & B3 (7) Station#2 : Pre-Buncher & RFQ (2) Station#4: DTL T4 &T5; HEBT 11MHz Buncher & 35MHz Buncher (4) DSB Station: DSB bunch (1)

8 Control Station #1(Rotator, Choppers) & #2(Pre-Bunncher, RFQ)

9 Control Station #3 (Mebt Rebuncher,T1…B3) & #4 (Tank4, 5, Hebt 11/35Mhz bunchers)

10 Tuners disabled in some systems Chopper 5MHz, Chopper 11 MHz MEBT Rebuncher & HEBT 11 MHz buncher One fine tuner is running for close loop RFQ (two coarse tuner), Bunch Rotator, DTL system & HEBT 35 MHz buncher (one coarse tuner) Coarse tuners can only be moved manually. Tuners in each rf device

11 Local turn on PA (PA local) Turn on PS (including AC breaks 480/208V), Reset PA, Turn on PA; reset to kill all red-light when PA ready Then switch PA control  remote Remote turn on PA (PA remote) Open control panel for turn on PA, Reset PA, Turn on PA (when ready, all green) How to Turn on Amplifiers

12 Local turn on RF (on Local control stations) PA ready for turning on rf, RF control programs on, (1) Set ‘Amplitude point’ at about 400 (2) Click ‘Auto on’ (*) Reset PA locally if PA trips off Remote turn on RF (Control rooms) PA ready for turning on rf, PA control programs on, (1) Set ‘Amplitude point’ at about 400 (2) Click ‘Auto on’ (*) Reset PA &Turn on PA if PA trips off How to Turn on RF

13 Reboot rf control program (just reboot one of the programs) Turn off rf, turn off the control program (do not save it!) Then restart the control program Reboot rf control program & rf control board (one only) Turn off rf, turn off the control program (do not save it!) and reset the knob of rf control board Then restart the control program Reboot VXI create and PC station Turn off all rf, turn off all control program (do not save it!) turn off PC ps (or restart) and turn off VXI ps (Turn on VXI, PC & RF while control programs on; always last off, first on) Rebooting system

14 Reboot PC, VXI Create & RF Control Board

15 DTL PA Control Panels 208V breaker 408V breaker

16 RF Control Pages in Local PC

17 RF Control Pages in Control Room

18 PA/RF Working Status page

19 RFQ RF Control Devices

20 Write down what you have done, what you saw for PAs status on the local notebook & on Operation’s Logbook Tell operator what you have done which may affect beams Waite for operator’s requests after repairing or maintenances Always Making Record after Jobs Done

21 Tubes RFQ (4CW150,000, Rf room), HEBT 35 MHz (4CW30,000, Rf room) Rotator (3CX3000A7, Cabinet close to RFQ) DTL (4CW25,000, Area back side HEBT PA ) Power supplies (Area back side HEBT PA ) DTLPA drivers, Bias/Screen ps HEBT 35/DSB Buncher Bias/Scrn ps RFQ filament ps, Pre-buncher amplifier HEBT 35/DSB Buncher (ISAC-II rf room) Tuners, couplers & spare parts (Cabinets close to RFQ) Spare Parts Locations
