CHAPTER 6 ACCELERATOR TEST FIRING RESULTS 6.1 Theoretical Performance The waveform for the drive current of one phase of the two phase push-pull drive circuit of mass Driver Two is shown in Fig. 6.1. Fig. 6.1 Current and voltage waveforms during the passage of one bucket coil. A computer program was written to calculate the energy transfer of the drive circuitry using actual values of firing delay, inductance, resistance, and capacitance for the different drive coil firings and including recharging. The values of inductance and resistance used can be found in Chapter 2. The circuit used for modelling the energy transfer is shown in Fig. 6.2. Details of the circuit analysis and difference equations used can be found in Appendix J.
