Alameda Applied Sciences offers a high-speed gas valve that operates on the principle of a conductive flyer plate accelerated by eddy currents induced by an adjacent coil. The low-mass flyer plate and backing spring combination provide a fast opening (<100 μs) and closing (<500 μs) time for the valve. Other commercially available solenoid valves typically open in 1 ms and close in several ms. In one embodiment of the AASC valve, a nozzle structure directs a supersonic flow of gas into a rectangular jet of high-density gas suitable for interaction with a laser beam transverse to the jet, for the production of laser wake-field interaction, leading to very high-energy electrons from the gas jet.
AASC builds valve drivers and custom gas manifolds to support our valves. We have designed a rep rated driver for our single plenum valves that is operational at up to 10 Hz. Our multiple plenum valve drivers operate in single shot mode. Each valve plenum can be fired independently.
Numerous emerging fields require an electrically controlled gas valve with faster response time.
AASC’s fast gas valves can be tailored to the customer's desired operating pressure and gas jet density. The rapidly closing valves allow operation at high repetition rates (10-100Hz), even at 1500 psia plenum pressure.
