Charge-sign dependent modulation of cosmic ray electrons and positrons up to extreme solar maximum conditions
Raath, J.L.; Potgieter, M.S. (PoS, 2017)The charge-sign dependent modulation of cosmic rays is an important topic in solar modulation studies, providing insights into gradient, curvature, and current sheet drifts. Such studies, at higher levels of solar activity, ... -
Constraints on the lepton content of PWN from the local CR positron spectrum
Büsching, I.; De Jager, O.C.; Potgieter, M.S.; Venter, C. (ICRC, 2008)Geminga is a nearby pulsar with an age of 3.42×105 yr and a spindown power of 3.2×1034 erg/s at present. B0656+14 has comparable spindown power, with an age of 1.11×105 yr and a distance of 290 pc. The winds of these ... -
A global view of the modulation of cosmic ray protons in the heliosphere for the solar minimum period up to 2009
Potgieter, M.S.; Vos, E.E. (IOP Publishing, 2016)The heliosphere was in a state of ideal solar minimum conditions for at least three years up to the end of 2009. During this period the highest ever recorded cosmic ray spectra were observed at the Earth. Fortunately, the ... -
Short-term variation in the galactic cosmic ray intensity measured with the PAMELA experiment
Munini, Riccardo; Potgieter, M.S.; Di Felice, Valeria; Boezio, M.; Adriani, O. (PoS, 2017)New results on the galactic cosmic ray (GCR) short-term intensity variation associated with Forbush decrease and co-rotating interaction regions (CIRs) measured by the PAMELA instrument between November 2006 and March ... -
Ten years of positron and electron solar modulation measured by the PAMELA experiment
Munini, Riccardo; Potgieter, M.S.; Raath, J.L.; De Felice, V.; Boezio, M. (PoS, 2017)The satellite-borne PAMELA experiment was launched on the 15th June 2006 from the Baikonur cosmodrome. Till January 2016 PAMELA has detected the charged component of cosmic-rays (CRs) over a wide energy range. Due to its ...
