Coil force integrals in Magnum

The magnetic force on a vector current element dl carrying current I in a magnetic field with flux density B is

dF = I dl × B    (1)

In Magnum applied currents are represented by a collection of filamentary elements, so you might think that it would be straightforward to implement automatic routines to find forces on drive coils. [...]

GamBet computing power unleashed

GamBet, our Monte Carlo code for X-ray science and technology, has always been ahead of competitors with regard to special features (I’ll mention some later). In the past other packages may have had more raw computing power. We advanced the number-crunching capability of GamBet last year when we introduced parallel processing (http://fieldp.com/myblog/2011/multicore-gambet/). With this feature, GamBet [...]

Multitasking made easy

Field Precision programs are optimized for the latest generation of multi-core or multi-processor PCs. The 64-bit major solution programs (HiPhi, Magnum, GamBet,…) feature true parallel operation. The time-intensive subroutines have been coded in OpenMP, giving significant improvements in speed (see magnum-in-parallel or multicore-gambet). A second feature is the capability to run multiple independent calculations simultaneously. All [...]

Website introduction video

We’ve added a lot of content to our website at www.fieldp.com in 13 years. In fact, there’s so much material that the site might intimidating to first-time visitors looking for software or educational resources. To help, we’ve added a short overview video on the home page. Here it [...]

Particle flux plots in Gendist

A recent consulting project involved Xenos simulations of an intense, non-circular electron beam striking a graphite beam stop. A phosphor plate on the downstream face of the target was used as a diagnostic. The researchers wanted to know how the shape of the phosphor response correlated with the shape of the beam. One option was to [...]
