Study of the coordinate prediction accuracy for galactic particles with an energy of 10–1000 TeV/particle using a new method for searching and tracking particles in nuclear emulsion films. (Data of the Russia–Nippon Joint Balloon (RUNJOB) experiment)

Аннотация

Experimental and methodological errors in the coordinate prediction for primary cosmic ray nucleons and nuclei in nuclear emulsions using a new method for searching and tracing particle tracks in emulsion films of X-ray emulsion chambers (XRECs) exposed in the stratosphere in the Russia–Nippon Joint Balloon (RUNJOB) experiment are considered in detail. The dependence of errors on the relation between angular characteristics of the sought particle and auxiliary multiply charged nuclei is analyzed. Angular selection criteria for auxiliary nuclei, at which the methodological error of the particle track coordinate prediction decreases, are found.
