Modeling radioactive sources with GamBet

Many processes represented by GamBet, such as the emission of bremsstrahlung photons and Compton electrons, involve interactions with atomic electrons. Particle emission may also follow from reactions within nucleii. Although GamBet does not address nuclear physics, the program can determine the histories of particles created by nuclear events. There are two types of processes: nuclear reactions […]

Magnum for MRI facility shielding

I recently had an inquiry from the president of a company that creates magnetic shielding for MRI facilities. In the past, the company installed iron sheets in response to customer specifications. The company’s current goal is to assume more design responsibilities by developing an in-house computational capability. Figure 1 shows a typical MRI facility along with […]

Generating arbitrary distributions with R

(This is tenth and final article in the series Using R for Gambet statistical analysis.[1]) The R package includes functions to create a wide array of distributions of interest in mathematics. Nonetheless, there are many particle distributions of interest in physics (such as differential cross sections) that are not directly represented. This article introduces a method […]

Creating GamBet SRC files with R

(This is ninth article in the series Using R for Gambet statistical analysis.[1]) The focus of this article is to learn how to generate particle distributions with R and how to export them in a form that can be used directly as input to GamBet. A second topic is how to run R scripts directly from […]

Importing GamBet files into R

(This is eighth article in the series Using R for Gambet statistical analysis.[1]) In the previous articles, we studied R techniques that would be useful to supplement most technical programs. In this article and the next, we’ll concentrate on integrating R with GamBet. The GamBet program produces two types of text data files [2] that can […]
