A new Condensed History algorithm is introduced to enhance the Monte Carlo simulation of electron transport problems. Unlike established multiple scattering algorithms, this method is a true transport process--it simulates a transport equation that approximates the exact Boltzmann equation. The new equation has a larger mean free path than, and preserves two angular moments of, the Boltzmann equation. Thus, the new equation conserves both particles and scattering power, and it is more efficient to model by Monte Carlo. We show that this ''Transport Condensed History'' algorithm more accurately predicts electron position as a function of path length traveled (energy lost) than current Condensed History schemes. We also show that it can move particles across material boundaries and interfaces with acceptable accuracy and efficiency.
