Abstract

This paper describes a type of cosmic ray detector for isotopic and energy detection of energetic nuclei which derives both dimensions of position information from one side of the detector. This simplifies the required readout electronics, since only one precision amplifier connected to the other side is required for an accurate detection of the energy loss. Two dimensional readout is enabled by the use of pixels consisting of closely spaced interdigitated electrodes alternately connected to row and column lines. Spreading of the charge produced by the cosmic ray results in the charge being collected by more than one electrode producing both a row and column signal on one side of the detector. The design, fabrication, and characterization of the interdigitated-pixel detector is discussed.
