    Abstract: An apparatus and method for video imaging the spatial response of radiation-responsive devices, such as photomultiplier tubes. The apparatus probes the device under-test with an array of radiation emitting elements, such as light-emitting diodes, programmed with a scanning sequence such that the device under-test output response, e.g., the anode current of a photomultiplier tube, may serve as a video signal to a video display device such as a television or monitor. A video image so produced provides a map of the spatial response of the radiation-responsive device which may indicate perturbances, flaws, and inhomogeneities in the spatial responsivity of the device.

    Abstract: A scheme for multi-frequency at-speed logic Built-In Self Test (BIST) is provided. This scheme allows at-speed testing of very high frequency integrated circuits controlled by a clock signal generated externally or on-chip. The scheme is also applicable to testing of circuits with multiple clock domains which can be either the same frequency or different frequency. Scanable memory elements of the digital circuit are connected to define plurality of scan chains. The loading and unloading of scan chains is separated from the at-speed testing of the logic between the respective domains and may be done at a faster or slower frequency than the at-speed testing. The BIST controller, Pseudo-Random Pattern Generator (PRPG) and Multi-Input Signature Register (MISR) work at slower frequency than the fastest clock domain. After loading of a new test pattern, a clock suppression circuit allows a scan enable signal to propagate for more that one clock cycle before multiple capture clock is applied. This feature relaxes the speed and skew constraints on scan enable signal design. Only the capture cycle is performed at the corresponding system timing. A programmable capture window makes it possible to test every intra- and inter-domain at-speed without the negative impact of clock skew between clock domains.

    Abstract: A gating circuit switches the responsivity of a photomultiplier tube between ON and OFF states by modulating the voltage bias of the one or more of its electrodes. The gating circuit capacitively couples a voltage pulse to the photocathode or other electrode of the photomultiplier tube in response to a low-voltage gating triggering signal. The voltage divider network and high-voltage power supply used to statically bias the photomultiplier tube also power the gating circuitry and source the gating voltage pulse, thus circumventing the need for a separate high-voltage power supply. The gating circuit represents a near-inconsequential burden on the power supply, as it draws practically negligible current from the voltage divider network. The electrode gating pulse characteristics, including rise- and fall-times, voltage swing amplitude and duration, can be modified by adjusting resistor and capacitor values and Zener diode characteristics of the gating circuit and voltage divider network. The circuit can also be used to gate related devices such as microchannel plates and image intensifiers.
