Cos-B carried a single large experiment, the gamma-ray telescope.
The gamma-ray detector features a magnetic-core, wire-matrix spark chamber, SC, triggered by a three-element (B1, B2, C) scintillation counter telescope. For gamma-ray selection a plastic scintillator guard counter (A) surrounding these two units is placed in anti-coincidence to reject triggers due to incident charged particles. Beneath the telescope is an energy calorimeter (E) consisting of a caesium iodide scintillator which absorbs the secondary particles produced by the incident photons.
