Workshop: Using MCNP5 for Medical Physics Applications
Sponsor: Computational Medical Physics Working Group
Cost: Free for Conference Registrants
Date: Sunday, April 17, 2005, 1-5PM

Monte Carlo techniques are increasingly popular in many medical physics applications. This half-day tutorial focuses on how to use new and old MCNP5 features for neutron, photon and electron transport problems. The tutorial will include handouts and some demonstrations by the instructor, but not hands-on computer activities for the student The following is a draft of the topics which will be covered:


1) Overview of new MCNP5 features
a) Mesh tallies
b) Photon Doppler Broadening
c) > 2.1 billion histories
d) Lattice tally enhancements

2) Geometries and Modelling
a) MIRD Phantoms
b) CT_based geometries

3) Sources

4) Tallies
a) Calculating dose w/ different tallies
b) Flux to Kerma factors (DE DF cards)
c) Calculating reaction rates

5) Misc
a) S(alpha, beta) neutron scattering treatment
b) Simple variance reduction
c) Benchmarking Studies - QUADOS
d) using PTRAC file for coincident counting
