Abstract :
The AGS (Alternating Gradient Synchrotron) booster tune meter kicker system consists of two identical kickers for horizontal and vertical tune measurements, and a control unit utilizing a programmable logic controller. The kicker modulators are line-type pulsers. The pulse energy stored in the PFN (pulse forming network) is discharged through a set of matched cables to the load magnet and a matching terminating resistor. Some RC compensation networks are used to obtain the fast rising pulse waveforms. The booster will cover a wide range of revolution frequencies. To cover this wide range, tunes will be measured by kicking the beams with two different pulse lengths. A switch mode power supply with fast command tracking speed is used for PFN charging and enables the kickers to change pulse amplitudes on a pulse-by-pulse basis. The pulse repetition rate can reach up to a maximum of 200 pulses per second (p.p.s.) at 20 kV and 2000 p.p.s. at 2.5 kV.<>
