Pilatus (Detector) (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pilatus is the name of a series of silicon pixel detectors developed at the Swiss Light Source, and commercialised by Dectris. The common factor is that X-rays are converted to an electrical signal by the photoelectric effect in silicon subject to a substantial bias voltage, and then counted directly by a series of cells in an ASIC bonded to the silicon detector, rather than relying on a phosphor. That is, each pixel has its own amplifier, discriminator and counter circuit; this is possible because the desired pixel size for X-ray crystallography is around 100 micrometres, and a 100 micrometre square in a contemporary CMOS process can contain a significant quantity of electronics.
