Abstract

MicroBooNE experiment will use a ∼ 100 ton Liquid Argon (LAr) Time Projection Chamber (TPC) detector, presently under construction, to observe interactions of neutrinos from the on-axis Booster Neutrino Beam and off-axis NuMI Beam at Fermi National Accelerator Laboratory. The experiment will address the low energy excess observed by the MiniBooNE experiment, measure low energy neutrino cross sections, and serve as the necessary next step in a phased program towards massive Liquid Argon TPC detectors. An overview of the front end readout architecture of the MicroBooNE experiment will be presented. The design, prototypes and the production electronics system, comprised of cold CMOS electronics, warm interface electronics and TPC digitizing electronics will be described in some detail. The results of extensive tests on the noise versus temperature and of the uniformity of response will be presented.
