We present a simple calculation of the flux of secondary positrons produced in the ISM that is based only on priors. Our calculated ISM flux agrees very well with that calculated with the elaborate GALPROP code. It confirms that secondary production of positrons in the ISM by the primary cosmic rays cannot explain the observed sub-TeV flux of CR positrons. Moreover, we show that once energy loss of positrons in source and in the ISM are included, secondary production inside the CR sources plus the ISM does explain the measured near-Earth flux of cosmic ray positrons.

    Using the Cannon-Ball model's original priors, the author computes a positron source spectrum whose shape matches AMS data, with an absolute normalization 23% higher than observed.
