Design and Construction of a 20- KJ Filippov-Type Plasma Focus

Abstract

UIPFF1 is a new Filippov-type plasma focus facility, constructed and built in Esfahan University. This paper reports on the design of the UIPFF1. The main stages of the construction, design and the preliminary X-ray detection tests on the UIPFF1 are mentioned concisely. Measurement results show that in a typical discharge experiment, the discharge current =181 kA, period of current signal = 7.9 µs, the total inductance of the device =132 nH and electrical resistance of the circuit = 77 mΩ. The calibration factor is measured as 121 kA/V by averaging from data obtained with a set of 5 experiments. Temporal changes in plasma focus discharge current, confirmed occurrence pinch at a specific pressure of argon, neon and nitrogen gases.
