HLI (High Charge State Injector)

Operating frequency: 108.408 MHz

Power amplifiers with transistor and vacuum tube stages provide RF power to the accelerating structures and bunchers of the HLI section.

Pulse power at duty cycles in the range 5...40%:

 RFQ     200     kW
 BB13       2     kW
 IH         200     kW
 BC2         2     kW
 BB14       2     kW

BC2 is no accelerating structure. It is used as a so-called "beam chopper".
