Abstract :
A broadband RF system has been built for the new Fermilab Recycler Ring. It is designed to both bunch and capture beam during transfers and create multiple, moveable RF barrier buckets for azimuthal control of the stored antiproton beam. Beam will be bunched and captured using bursts of four RF cycles at 2.5 MHz. To maximize bucket area, the multiple barrier buckets will be generated by pairs of 2000 V bipolar square pulses (1 to 2 μs in duration). The high level portion of the system consists of four 50 Ω ferrite loaded cavities, each driven by a 3.5 kW broadband (10 kHz-100 MHz) solid-state amplifier
