Simulations of the heating of a vitreous sample by the electron beam. (a) Temperature versus time plot for a lumped system model for three different heat-transfer coefficients h. The adiabatic model temperature rise is shown in comparison. One-dimensional heat-diffusion plots for a distributed model are shown for (b) medium- and (c) high-flux incident beam for a low heat-transfer coefficient of 800 W m−2 K−1. |
