IBIS PCSS Product IconIBIS™ Photoconductive Semiconductor Switch

From our research and development efforts, our scientists have created a compact gallium arsenide-based switch capable of handling ultrahigh voltages (over 75,000 V) and current densities in less than a billionth of a second, with ultralow jitter.

Applications that require rapid application of high voltages will benefit from this technology breakthrough. The initial application for IBIS™ PCSS enables a portable capability for future nuclear weapon effects evaluations to ensure sufficiently hardened equipment.

Our challenge was to improve the structural efficiency of launch systems by replacing the Ti-5Al-2.5Sn ELI alloy for Liquid H2 Turbopump Impellers with an aluminum-based alloy. Aluminum is about 1.6 times lighter and is less sensitive to the hydrogen environment. Al-7042 exhibited good properties over a broad temperature range (-269˚ C to 100˚ C). A Liquid H2 Turbopump Impeller was fabricated and successfully spin tested.

The Super High Strength AI Alloy 7042 offers:

  • Direct Chill cast 7042-T6 has mechanical properties similar to 7075-T6 or 7050-T74 forgings, but with superior stress-corrosion resistance as compared to these alloys
  • Forged products made from 7042-T6 are 25-35% stronger and tougher than similar forgings made of 7075-T6 and 7050-T74 alloys
  • Extruded 7042-T6 products have ~30% higher specific strength than Ti alloys
