    "abstract": "We describe a compact apparatus that automatically measures the charge\naveraged lifetime of atmospheric muons in plastic scintillator using low-cost,\nlow-power electronics and that measures the stopping rate of atmospheric muons\nas a function of altitude to demonstrate relativistic time dilation. The\napparatus is designed for the advanced undergraduate physics laboratory and is\nsuitable for field measurements.",
