During the fall of 1979 circuitry was constructed to simulate the firing of a bucket to test the SCR trigger and optical trigger circuitry, see Chapter 5. During this period instrumentation to measure voltages, currents, and periods were designed and constructed. Further refinements and additions to this instrumentation circuitry was continued through 1980 and is shown in Fig. 1.4. Fig. 1.4 Mass Driver Two instrumentation and control circuitry. A simplified recharge system was assembled in early 1980 to test the simplified switching circuit proposed then, see Chapter 4. After being proved feasible for the full scale system, work proceeded on completing the feeders and fusing for the recharge capacitor bank. Design and construction of the circuitry to automatically control the recharging was begun during the summer of 1980, see Chapter 4.
