Replacing Launchpad on the Mac

LaunchPad on the Mac is an attempt to replicate the main screen in Windows — an area filled with icons to launch installed programs (shortcuts in Windows parlance). There is one big difference. In Windows, users can add or remove shortcuts. In macOS, the process is performed automatically — users are prevented from making any changes. This follows from the […]

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 […]

OmniTrak: superposition of magnetic field tables

OmniTrak is our software package for charged-particle guns and beam dynamics. The solution program can read output files from HiPhi and Magnum for 3D electric and magnetic field information. These complex files record values of potential on conformal meshes. Tables are another option for field information. Tables record [Ex,Ey,Ez] or [Bx,By,Bz] on a regular box mesh. […]

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 […]

Moving thermal sources in HeatWave

The generation of X-rays via bremsstrahlung is energetically inefficient at electron beam energies of interest for medical applications. Therefore, high-power electron beams are necessary for procedures such as CT scans. Dissipation of energy to prevent target melting is a major issue. One solution is a rapidly-rotating target. Alternatively, we recently worked with a customer using a […]
