VASIMR VX-200 Reaches 200 kW Power Milestone (with videos), Ad Astra Rocket Company
"Ad Astra Rocket Company's VASIMR(R) VX-200 rocket prototype reached its highly- coveted 200 kW maximum power milestone at 11:59 am (CST) in tests conducted at the company's Houston laboratory. The DC power trace actually exceeded the design requirement by 1 kW and exhibited the clear signature of a wellestablished plateau at peak power (see graph). The achievement comes after an intense experimental campaign that began last April when the engine was fitted with a powerful low temperature superconducting magnet, a critical component that enables VASIMR(R) to process large amounts of plasma power. The electrical power processing is accomplished using high efficiency, 95%, solid state RF generators built by Nautel Ltd of Halifax, Canada."
