Abstract
A device for the collection, digitization and analysis of synchrotron x-ray crystallographic data using an area detector which detects x-ray photons directly on arrays of solid state detectors and stores the information on capacitors located on readout unit cell array chips. The device consists of a two dimensional area detector, for amplification, collection and conversion of the diffracted x-rays to electrical signals, drive electronics for providing the timing pulses and biases to the area sensor, output electronics for converting the x-ray signals to digital signals and storing the signals, and a data processor to analyze the digital signal form the output electronics. The solid-state detector array is made up of a variable-area three-dimensional array of detector array chips where each chip is in turn made up of an array of solid-state detectors. Each detector on the detector array chip is electrically connected to a readout unit cell on a readout array chip directly beneath the detector array chip. The readout unit cell contains the circuitry for storage, switching and readout of the x-ray signals.
