Description
| - Experimentální studie využívající dat družic Cluster, která se zaměřuje na pozorování částic urychlených na supratermální energie v oblasti Cuspu. Rovněž jsou diskutovány možné dopady na inicializační proces substormů. (cs)
- The purpose of our study is to investigate the way particles are accelerated up to supra-thermal energies in the cusp diamagnetic cavities. For this reason we have examined a number of Cluster cusp crossings, originally identified by Zhang et al. (2005), for the years 2001 and 2002 using data from RAPID, STAFF, EFW, CIS, PEACE, and FGM experiments. In the present study we focus on two particular cusp crossings on 25 March 2002 and on 10 April 2002 which demonstrate in a clear way the general characteristics of the events in our survey. Both events exhibit very sharp spatial boundaries seen both in CNO (primarily single-charged oxygen of ionospheric origin based on CIS observations) and H+ flux increases within the RAPID energy range with the magnetic field intensity being anti-correlated. Unlike the first event, the second one shows also a moderate electron flux increase. The duskward electric field Ey has relatively low values <5 mV/m while the local wave activity is very intense.
