Title: A Compact, Flexible, High Channel Count DAQ Built From Off-the-Shelf Components

Medium to large channel count detectors are usually faced with a few unattractive options for data acquisition (DAQ). Small to medium sized TPC experiments, for example, can be too small to justify the high expense and long development time of application specific integrated circuit (ASIC) development. In some cases an experiment can piggy-back on a larger experiment and the associated ASIC development, but this puts the time line of development out of the hands of the smaller experiment. Another option is to run perhaps thousands of cables to rack mounted equipment, which is clearly undesirable. The development of commercial high-speed high-density FPGAs and ADCs combined with the small discrete components and robotic assembly open a new option that scales to tens of thousands of channels and is only slightly larger than ASICs using off-the-shelf components.
