From 2000 to 2010, the Belle experiment in Tsukuba, Japan collected data from electon-positron collisions delivered by the KEKB accelerator. The resulting dataset helped confirm the theories of Kobayashi and Maskawa, who earned the Nobel Prize in 2008 for their explanation of the source of matter/antimatter asymmetry. In early 2016 SuperKEKB, an upgrade to KEKB, will begin circulating beams in anticipation of delivering forty times the luminosity of its predecessor to an upgraded detector, Belle II. The University of Hawaii is leading an international team of Belle II collaborators to build a suite of detectors at SuperKEKB to measure and characterize the backgrounds generated by these unprecedentedly powerful beams at the location where Belle II will be installed. We refer to this motley assortment of detectors from three continents as "BEAST II", in honor of the project, also led by UH, that prepared the way for Belle. BEAST II can be thought of as a digestible-scale collider experiment, and I will present the design and current status of the project as an introduction to the techniques, challenges and concepts of experimental high-energy particle physics. This talk is intended to be accessible to UH physicists in all subfields.
