A high-speed high-voltage pulser especially designed to operate in high radiation environments. The pulser uses a primary side driver and switches in front of an isolation gate transformer. The primary side driver and switches provide amplified and fast complementary pulse signals to the transformer. The transformer has top and bottom secondary windings, which respectively receive the complementary signals, and deliver them to secondary side drivers and switches. The switches are implemented with series-connected FETs.

Radiation-tolerant high-speed high-voltage pulser

A test fixture for testing the operation of a device having components installed at a first location. The components are connected to associated apparatus installed at a separate second location, and the components collectively have electrical inputs and outputs connected to a control at the second location. The test fixture has a housing and a plurality of output conductors at the first location. First ends of selected ones of the plurality of output conductors are connectable to selected ones of the inputs and outputs of the components. A power supply and a plurality of switches are mounted to the housing. Each of the plurality of switches has one contact connected to the power supply and another contact connected to a second end of respective one of the plurality of output conductors, whereby actuating one of the switches causes a respective one of the components to operate.

Test fixture for a liquid recirculation unit

A test fixture and method emulate the inputs and/or outputs to a controller and motor of a spin rinse dryer to permit selective testing of the controller and/or motor thereof. In some instances, the test fixture enables testing of a spin rinse dryer controller and/or motor to be performed outside of a clean room environment, and without requiring a spin rinse dryer to be taken off-line. In other instances, the same test fixture enables diagnosis of which component if any has failed in a production spin rinse dryer so that the failed component can be replaced quickly to minimize the downtime of the equipment.
