Nature of problem:
DEPOS is a code module that computes the energy deposition of monoenergetic fast electrons normally incident on a one-dimensional slab absorber.

Solution method:
The numerical algorithm is based on the parametric fits of Tabala and Ito, valid for atomic number 5.3 <= Z <= 82 and for kinetic energy 0.1 MeV <= T<= 20 MeV. Emperical equations that were developed for the extrapolated range and backscattering of electrons are utilized and bremsstrahlung production is included. Adjustable parameters are least squares fit to experimental and Monte Carlo results and overall agreement is excellent.

Running time:
DEPOS processes electron energy deposition profiles in under 1 s of CRAY-1S time.
