Comparison of energy transport measurements and computer simulations in a single module prototype for PBFA II
The 36-module Particle Beam Fusion Accelerator (PBFA II) is designed to provide a 30 MV pulse, with greater than 150 TW, to a centrally located lithium ion diode. Each module is driven by a 6 MV, 400 kJ Marx generator and uses three water-insulated and switched pulse compression stages followed by a voltage inversion-adder unit. All impedance matching transmission-line transformer couples the output pulse from the inversion-adder unit to the central vacuum insulator, plasma erosion switches, and ion diode. The prototype of a single PBFA-II module, called Demon, is being used to test component design, including a mock-up of a section of the vacuum insulator, and to determine overall module operatting characteristics. This paper presents the results of measurements of energy transport efficiencies through the successive pulse compression stages. Results of energy transport measurements on an 18 module, one-fifth scale model, are also compared to the single-line data. We present a comparison of measured parameters with computer circuit code simulations of the hardware design. Comparisons are used to suggest areas of possible improvements. The measured module output characteristics agree with the code simulations and meet the design requirements for the PBFA-II accelerator.
