  • Langstaff, David; Birkinshaw, K. (2005-12-22)
    A charge detector array for recording signals from a microchannel plate (MCP) in which a synchroniser circuit (14) is provided in respect of each of a plurality of channels, interposed between a respective charge amplifier ...
  • Chase, Thomas Robert; Evans, D. A.; Langstaff, David; Bushell, A. (2005-08)
    In electron spectroscopy, multi-channel detection combined with intense radiation sources provides the optimum experimental configuration. Building on the 5 mm, 192-channel ion detector developed at Aberystwyth, longer ...

  • Langstaff, David (2002-04-01)
    Various position sensitive readout systems for microchannel plates are considered. A discrete anode detector with 192 channels and integrated data acquisition electronics developed at the University of Wales, Aberystwyth ...
  • Langstaff, David; Chase, Thomas Robert (Elsevier, 2007-04)
    A one dimensional detector array using MCP technology in conjunction with a custom ASIC is presented. The ASIC features 768 pixels, each 3mm in length on a pitch of 25µm, giving a length in the dispersive direction of 19.2 ...

  • Langstaff, David; Zhu, Xi (2009-06-01)
    We present a scheme for reducing multiple triggering based on a “first-past-the-post” voting circuit interposed between the sensor amplifier/discriminators and the counters in an event-counting detector. We are currently ...
