    Abstract: A charge read-out structure for photon and particle detectors, which is capable of spatially-resolving a position of the charge. The structure comprises a resistive element defining a detection surface which is capacitively coupled to an array of electrically insulated electrodes. Each electrode in the array is capacitively coupled to an adjacent electrode in the array to form a capacitively coupled network of electrodes. Selected ones of the electrodes in the array are each coupled to an array output for connection to a respective charge measurement device. The resistive element has a resistivity sufficient to temporarily localize a charge induced on the resistive element to an area corresponding to a subset of said electrodes in the array and for a duration sufficient for signal measurement from the array of electrodes. Charge measurement devices are coupled to selected electrodes in the network such that the spatial position of a charge event in the network can be determined by comparing the outputs from each charge measurement device.

    Abstract: The present invention comprises a method for gating a power supply. A gating command terminal is capacitively coupled to an on/off switch. A gating command signal is provided at the gating command terminal. The gating command signal is operable to activate the on/off switch. An off signal is generated at an output terminal of the on/off switch in response to an off state of the on/off switch being activated. An on signal is generated at the output terminal in response to an on state of the on/off switch being activated.
