National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Simulating variable source problems via post processing of individualparticle tallies.

DE2001782537

Publication Date	2000
Personal Author	Bleuel, D. L.; Donahue, R. J.; Ludewigt, B. A.; Vujic, J.
Page Count	8
Abstract	Monte Carlo is an extremely powerful method of simulating complex, three dimensional environments without excessive problem simplification. However, it is often time consuming to simulate models in which the source can be highly varied. Similarly difficult are optimization studies involving sources in which many input parameters are variable, such as particle energy, angle, and spatial distribution. Such studies are often approached using 'brute force' methods or intelligent guesswork. One field in which these problems are often encountered is accelerator-driven Neutron Capture Therapy (BNCT) for the treatment of cancers.
