Gyration time and radius of electron tracks in vacuum in magnetic fields. (A) is the gyration time and the radius of monoenergetic electrons in vacuum as a function of incident electron energy. (B) is the gyration radius in vacuum and the projected range in liquid water for electrons with energy from 102 to 103 keV. In Fig. 3A, the monoenergetic electrons were simulated in various SMF strength (B = 0.0–10.0 T). In Fig. 3B, the radius in vacuum with magnetic fields (blue circle) was compared to the range in liquid water without magnetic fields (cross symbols) and that in B = 3.0 T (plus symbols). The results show that the range for electrons below a few hundreds of keV is sufficiently smaller than the gyration radius in vacuum, suggesting the impact of Lorentz force is not significant.
