HEAVY PRIMARY COSMIC RAYS. Final Technical Report
Technical Report
·
OSTI ID:4229091
Techniques for processing 600 micron thick electron sensitive nuclear emulsions are described and suggestions are given for beginners in emulsion plate scanning adapted to heavy nuclear projects. Since the chief way to identify heavy nuclei which produce tracks in emulsions involves delta rays, considerable attention is devoted to a procedure which will give consistent results. The charge identification of heavy nuclei by use of emulsions of different sensitivities is also discussed. Data regarding heavy primary cosmic rays at geomagnetic latitude of 41 deg N near the geomagnetic equator, and at g.m. latitude of 55 deg N are presented. The relationship between ground level neutrons and high altitude heavy primary cosmic rays is discussed. (auth)
