Abstract

In this paper the characteristics of a cosmic-ray spectrograph which uses a solid iron magnet as the deflecting element are described. The particle tracks are registered by six spark chambers having double gaps. These spark chambers are triggered by four layers of G-M counters which are used also for a preselection of the momentum up to 50 GeV/c. The deflection power of the magnet, ∫B"∙dl, is 3.2 × 10⁶ gauss-cm; the momentum range is 7–5 000 GeV/c; the collection power amounts to 7.1 cm² sr, and the measured rate is 18/h.
