Modifications of the LANL-antares Marx tank proposed by PSI are shown in the drawings attached. They aim at maximum flexibility in providing various options for connecting the high voltage output of the Marx to the vacuum load. As shown, a large diameter flange has been designed for the front plate of the tank, onto which a 4-ft. diameter anode cylinder can be bolted. By placing an anode cylinder-vacuum tube assembly in the oil tank, as depicted, the minimum inductance, direct connection of the power supply to the load can be facilitated. With the same assembly mounted outside of the Marx tank there is room available inside for dielectric peaking capacitors and an output gas switch. For this scheme it is visualized that a single-gap, self-breaking gas switch with field-enhanced electrode will be used in combination with about 25 nF solid dielectric capacitors (e.g. two parallel stacks of 14--100 kV, Maxwell type 31426SS connected in series. An alternative option, offering minimum inductance contribution to the circuit, is available by using a 4-ft. OD coaxial water capacitor for peaker between the Marx and a gas switch/vacuum tube combination. Preliminary estimates show that a 25 nF water capacitor operating at negative 1 MV and 4.3 ps decay with E[sub BD]/E[sub max] - 1.3 ratio requires about 6.5 feet length.
