Description

By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary. Learners model the collection of particles called Energetic Neutral Atoms (ENAs) by the Interstellar Boundary Explorer (IBEX). If you need an audio version of this material, the file is compatible with screen reading software such as Adobe Acrobat Reader.

Materials List (per group of students)

  • 4 medium-sized buckets/boxes painted or covered with colored paper and numbered as indicated in the Set-up Diagram (p2 of PDF)
  • 2 pieces of stiff cardboard or lids to cover the buckets when not in use
  • 50-100 small beanbags (red, orange, yellow, green and blue), a cheaper alternative may be balloons filled with sand or rice.
  • masking tape
  • IBEX spacecraft poster or picture
  • 16 clear tubes or cylinders (e.g. graduated cylinders) that are big enough in width to accommodate the beanbags numbered as in the diagram
  • an area at least 10ʼx10ʼ

Detectors designed for modern

Detectors designed for modern accelerators are huge, both in size and in cost. The term counter is often used instead of detector, when the detector counts the particles but does not resolve its energy or ionization.
