Abstract

We have measured the effect of a 10 kG magnetic field on the dose distribution of electrons in a polystyrene phantom. Isodensity plots and depth dose curves are presented for 22 and 28 MeV electron beams with and without the magnetic field applied. The measurements show that magnetic fields as low as 10 kG can produce a substantial modification of the absorbed dose distribution. When compared with the zero magnetic field distribution of the same energy, the magnetic field significantly improves the D_max surface dose ratio and increases the fall off in dose past the D_max region.
