1 INTRODUCTION

1.1 Description

This equipment will be used as part of the Gamma-t power supply. The specification is for the individual Resonant Jump Capacitors (Cjump1 and Cjump2 in Figure 1).

1.2 Configuration

The Gamma-t power supply is a capacitor-discharge pulser that generates a ±878 A peak half-cosine wave pulse in a triplet string of quadrupole magnets. The pulse length is 0.75 ms and repeats every 0.65 s. There will be a total of four of these supplies discharging into four separate inductive quadrupole triplet loads.

The circuit works by charging a 150 mF capacitor bank and then discharging it into the magnet load through three IGBT switches. IGBT1 and IGBT2 will close, charging the magnet load, the charge pump inductor, and the jump capacitors

After 5ms, IGBT1 and IGBT2 will open, creating a resonant circuit between the jump capacitor and the magnet load that will generate a half-cosine wave from +878A to - 878 A in 0.75 ms. This causes the energy in both the charge pump inductor and magnet load to transfer to the jump capacitors. The charge pump inductor is required to achieve a symmetrical jump waveform by offsetting the energy losses from the transition.

Once the voltage of the jump capacitor reaches 0 V, IGBT3 is closed, forming an RL circuit. This then allows the current to decay through natural losses of the cable and magnet.

The purpose of the jump capacitors is to create a 667 Hz resonance between it and the magnet load. They must be able to effectively store and transfer the energy of the magnet load and the charge pump inductor to effectively ring the magnet current from +878 A to -878 A in 0.75 ms.

2 SCOPE OF WORK

The vendor shall manufacture and test the capacitors Cjump1 and Cjump2 in Figure 1.
