Abstract
An ionization detector having a grid of electrodes disposed perpendicular to an oscillating voltage. Charge released from an ionization event oscillates in the detector medium at the same frequency as the applied oscillating voltage. The electrode grid is configured to measure induced oscillating charge from the oscillating ionization charge in the detector. The detector signal is obtained from readout of the induced oscillating charge on the electrodes. Signal processing electronics processes the measured signal from the oscillating induced charge to derive energy and position information of the ionization event. A bias voltage is applied across the detector to further sweep the ionization charge from the active detection volume.
