Installing Field Precision utilities on a Mac

We have recently ported our technical productivity resources to Mac computers. The programs are distributed free of charge to scientists, engineers and students. They run under the latests versions of macOS on computers with Intel processors. Our utility programs include the full set of features and contain no advertising.

The following packages are available:

FP Uniscale. An advanced screen […]

Modeling quadrupole mass analyzers with OmniTrak

Linear quadrupoles are widely used for ion mass spectrometry. They can separate ions by the ratio of mass number to charge number (M/Z) without a magnetic field, leading to compact, light and inexpensive systems. An assembly consists of a source of low-energy ions that enter an extended electrostatic¬† quadrupole. The voltage applied to the lens has […]

GamBet shielding calculation walkthrough

In a previous article, I discussed the basis of the H*(10) standard for radiation safety. Here, I’ll continue by demonstrating techniques for shielding calculations. I’ll use a published simple benchmark calculation to compare the results to several other Monte Carlo codes and to illustrate some of the advantages of GamBet. For this, I am grateful to […]

H*(10) calculations with GamBet

I recently had an inquiry from a prospective customer. He had investigated several Monte Carlo options and was impressed with one package because the developer emphasized that the software could perform H*(10) calculations. In reality, every Monte Carlo X-ray code has this capability. The only requirement is that the user be aware of the definition. To […]

Variance reduction techniques in GamBet

The GamBet software suite calculates the interactions of energetic photons, electrons and positrons with matter. In a previous sequence of three articles (Monte Carlo methods versus moment equations: Part A, Part B and Part C), I discussed how Monte Carlo calculations approximate the behavior of large collections of particles. The essence of the Monte Carlo method […]
