If you would like more information on the following programs, or would like to use them for your personal work, please contact me. Part of the reason they are not available for download is that I created them while working for Crocker Nuclear Lab, and thus they belongs to them. But if I know exactly what you're looking for, I can certainly ask for permission to distribute them.

Beam On! (Completed, Visual Basic)
Though not initially developed by me, Beam On! is a program I put a lot of hours into. It is Crocker Nuclear Lab's primary cyclotron control program for visiting researchers (or, as the terminology goes, "outside users"). The program was originally written in Visual Basic, a language I did not know at the time. But it wasn't too hard to pick up. My addition was primarily upgrading the code to work on different machines, making the interface more intuitive, and adding a variety of features.

FileCaller (Status: Completed, v1.3)
FileCaller is a data analysis program I created for Crocker Nuclear Lab to determine the elemental content in "loaded" Teflon filters. That is to say, filters that were placed in the atmosphere above national parks, outside cities, etc. all contain some amount of pollution. A filter right outside of Detroit has more pollution than, say, Yosemite. One of Crocker Lab's primary contracts is to analyze the type of pollution on these files. This process can be tedious, as there are literally thousands of said filters, and expensive (beam time can be $600/hr). Using an algorithm Dr. Carlos Castaneda and I developed, I wrote this program to run through the "fresh" data and determine the pollution composition. The algorithm is similar to the one in my publications. This program reduced our group's file analysis time from one or two filters per day, to one filter per five seconds.

Spectrobuddy! (Status: Under Construction)
Spectrobuddy! is my current project. Its goal is to act as a "sidekick" to spectroscopic data analysis. Other than containing preloaded reference tables, I plan for it to do rudimentary data analysis such as peak fitting and elemental extrapolation. Currently, I am adding various X-Ray series reference tables. When it is complete, Spectrobuddy will be free (as in beer). This is a personal project not affiliated with either CNL or the UCD Physics Department. It is being coding in C# using Visual Studio 2003.
