High Power CW-RFQs
CW or pulsed. If the averaged power loss on the structure is several kW or more, we enter the high power regime and require an efficient cooling system and rugged RF contacts and shielding.
New developments in high performance RFQs:
- more efficient cooling system through new production methods
- Aluminum tank for better heat transport
- improved RF shielding on feedthroughs.
- Increased manufacturing precision and thus improved efficiency (shunt impedance)
First test results on a 4-stem model are available. More than 100 kW / m (90 kV electrode voltage) were reached. On basis of these experiences, the MYRRHA RFQ was developed, a 4 m long 1.5 MeV / u accelerator for cw proton operation at 5 mA. The production including adjustment and high-frequency adjustment were carried out at NTG.
