  1. Case Monte Carlo Simulations 4/17/2008

  2. Toolbox • MCNP5 – the grunt work • Polimi – low energy stuff • Matlab – post processing

  3. MCNP/Polimi Procedure • Create an input file for MCNP with geometry, filling material, etc each stored in a card • Polimi has set sources so you can call a Cf-252 source whereas in MCNP you define a Watt fission spectrum for your source • Run through Polimi and get out a data file with position, timing and particle information

  4. Polimi Output

  5. Processing Time Projection Event History Event Projection Events that meet the 2MeV cut 100ns bins

  6. Reproduce UCSB plots • Two runs (a) with GdCL3 0.2% by mass and (b) just water • 4000 total events (cuts down on iteration time) • Same cylinder size and source placement

  7. Timing distribution

  8. Thrown Neutron Spectrum

  9. Rate vs Multiplicity
