Latest Patents

Lafferty's latest patents include an "X-ray imaging apparatus with control mesh" and a "High-current vacuum switch with reduced contact erosion." The x-ray imaging apparatus features a gas-filled chamber bounded by a photocathode and a charge-receiving sheet anode. It incorporates a control mesh positioned in the gas-filled gap, which is maintained at a positive voltage to facilitate high avalanche amplification. This design achieves nearly constant efficiency of charge collection at the anode, independent of charge accumulation. The high-current vacuum switch patent addresses the issue of excessive contact erosion in high-current devices. By ensuring rapid transfer of the arc from the contacts to auxiliary electrodes, Lafferty's design minimizes erosion by using refractory metals for contacts and easily vaporized materials for auxiliary electrodes.
