Helical magneto-cumulative generator 280 mm in diameter

摘要

Several possibilities of preamplifier energy and power increasing are considered: using a more powerful (HMX-based) conical HE-charge in the central tube of the magneto-cumulative generator, using a magnetic flux finish pressing out device with axial initiation of the HE charge, and increasing the inner diameter of the helix. A magneto-cumulative generator (MCG) with a helix 280 mm in diameter (MCG-280) is developed. The new preamplifier has a power of a parts per thousand 400 GW and is able to power a ten-element DMCG480 with an initial inductance of a parts per thousand 0.2 A mu H by a current of a parts per thousand 10 MA with a characteristic current rise time (by a factor of e at the final stage of its operation) tau (e) = 32 A mu s.
