CHAPTER 2 ACCELERATOR 2.1 Drive Circuit The two phase push-pull drive circuit used in Mass Driver Two is shown in Fig. 2.1. Details of the circuit, operating conditions, and drive coil designs can be found in APPENDIX I. Construction of drive coils used in Mass Driver Two are shown in Fig. 2.2 to Fig. 2.5. Fig. 2.1 Six drive coils of phase 1, shown at the time of peak positive current; at this time there is zero current in phase 2. Four coils are excited, one to pull and one to push each of the two bucket coils. Spacing is chosen equal to the separation between a drive and bucket coil at peak gradient dM/dx. SCR's are triggered through pulse transformers for electrical isolation between the drive circuit and the electronic triggering circuitry.
