Magnetic mass spectrometer search at 2750 m. for hypothetical massive particlesA search was conducted for hypothetical singly charged massive particles which might be produced in collisions of very highly energetic cosmic ray particles with nuclei in the upper atmosphere. If such particles have sufficiently long lifetime and small cross section for interaction, they could survive to mountain altitude. A cosmic ray spectrometer consisting of superconducting magnet, wire spark chambers and time-of-flight scintillation counters was used to search for these particles at mountain altitude (2750 m). For any choice of hypothetical mass in the 5 to 10 GeV/c-squared range the upper limit to the vertical intensity of the particle was observed to be less than or roughly equal to 10 to the -6th/sq. cm/s/(GeV/c).
