Backstreaming ion populations propagating along the interplanetary magnetic field are evidenced upstream of the Terrestrial curved bow shock and form the ion foreshock. Two distinct backstreaming populations have been firmly identified by spacecrafts within the quasi-perpendicular shock region (i.e. for 45° <= Theta_Bn <= 90°, where Theta_Bn is the angle between the shock normal and the upstream magnetostatic field): so called (i) field-aligned ion beams (
