Calibration of the DRAGON DSSSD end detector
The double sided silicon strip detector, or DSSSD, a position sensitive, segmented semi-conductor diode detector, is one of the options commonly used as an end detector at the DRAGON facility1. This detector, often used in conjunction with another detector, such as an MCP (micro-channel plate) can offer a wealth of information during experiments, including the number and energy of particles detected, as well as positional information, and when used in tandem with another detector, local timing information.
The DSSSD consists of 16 front strips orthogonal to 16 back strips, which creates a pixilated detection surface, allowing position information to be extracted for each particle incident on the detector. However, since each strip uses its own electronics, an important step before the detector can be used in an experiment is calibration to ensure all channels (adc and tdc channels) are gain and offset matched, as well as energy calibrated.
