Description

A cosmic ray mass spectrometer with superconducting magnet, wire spark chambers, and time-off-flight scintillation counters was used to search for massive singly charged particles at 2750 m. altitude. For any choice of hypothetical mass in the 5 to 10 GeV/c2 range, the upper limit to the vertical intensity was 10-6 cm-2 sec-1 (GeV/c)-1. For comparison, observed fluxes and upper intensity limits are given for anti p, t, 3He, and α particles. (orig.)

Abstract (German)

Fuer die Suche nach schweren einfach geladenen Teilchen in 2750 m Hoehe wurde ein Massenspektrometer mit einem supraleitenden Magneten, Drahtfunkenkammern und Laufzeitszintillationszaehlern verwendet. Unabhaengig von der hypothetischen Masse im Bereich 5-10 GeV/c2 betrag die obere Grenze nur vertikalen Intensitaet weniger als 10-6 cm-2 sec-1 (GeV/c)-1. Zum Vergleich werden fuer Antiproton, t, 3He und α-Teilchen auch die beobachteten Fluesse und obere Intensitaetsgrenzen angegeben. (orig.)
