A position-sensitive large-area microchannel plate detector with digital data-acquisition system for studies of exotic nuclei.

Development of a position-sensitive large-area microchannel plate (MCP) detector based detection system is reported. Two MCPs with 120 mm active diameter, mounted in chevron configuration, with delay-line anode are read out by a digital data-acquisition system consists of fast-timing amplifier unit and CAEN v1751 waveform digitizer. Details of the digital pulse processing, programmed triggering and calibration setup are described. The obtained position resolution was studied using α -particles, the best resolutions on X and Y axes are 460 ± 1 μ m and 579 ± 1 μ m in FWHM, respectively. [ABSTRACT FROM AUTHOR]
