It’s likely that you’ve heard or read about many of the exciting discoveries in particle physics research at Fermilab. Powerful particle accelerators, including the Booster synchrotron with its unique ferrite-tuned RF cavities, consistently bring the lab to the forefront of discovery. Upgrading the 40-year-old Booster RF cavities will enable them to produce and sustain particle beams at even higher intensities… but will they overheat? Learn how the engineers at Fermilab address this important design challenge.

Spectroscopic imaging has been used for decades to map the chemical composition of material surfaces with atomic-scale resolution. In order to achieve adequate chemical specificity and spatial resolution during imaging, both the material sample and the imaging system are placed under high or ultra-high vacuum (UHV). In practice, materials are often used outside of vacuum environments and therefore it is also necessary to evaluate their surface properties at higher or ambient pressure. Differential pumping is the key to designing vacuum […]

The mining industry pre-dates sophisticated simulation software and the computers it runs on by thousands of years. As an essential modern industry, however, the technical and analytical capabilities offered by AMPHOS 21, a COMSOL Certified Consultant, are critical for both understanding and optimizing mine operations. Recently, we sponsored a webinar together with NASA Tech Briefs on “Mining and Hydrogeology: Porous Media Flow Simulations with COMSOL”, featuring environmental consultants Jorge Molinero and Elena Abarca from AMPHOS 21. Here are some of […]

A team of medical physicists at the Cross Cancer Institute in Alberta, Canada has come up with an innovative approach to treat cancer. In affiliation with The Linac-MR Project, the team led by Gino Fallone aims to improve the accuracy of cancer treatment by reducing damage to healthy tissue surrounding a tumor site, while ensuring the tumor receives the intended radiation dose. They are accomplishing this through the development of a hybrid linear particle accelerator (Linac) integrated with magnetic resonance […]

The unique properties of radio frequency (RF) electromagnetic radiation enabled countless innovations in recent decades, including the development of radar systems. Depending on the frequency, RF radiation can travel through solid insulating structures, typical atmospheric conditions, clouds, and rain with only minimal losses allowing for its use over long ranges and in varied weather conditions. The aerospace and defense industries have expanded and progressed rapidly as a result of using radar systems for detection and classification tasks to determine if […]

Equation-based modeling is one of the great strengths of COMSOL Multiphysics. The ability for you to easily access the equations describing the physics you are working with, and adding or manipulating them as you see fit, dramatically opens up the realm of possibilities that you can achieve through modeling and simulation. This is exemplified by the following custom model of a beating heart.

If you enjoy ketchup with your food, there’s a good chance you’ve experienced what we’ll call here the all-or-nothing ketchup quandary. You know, that moment when you reach for a new glass bottle of ketchup, remove the cap, and turn the bottle practically upside down — and then nothing happens. Intuitively you shake or tap the bottle, and then suddenly your food is completely coated in ketchup (unless your reflexes are really good, of course). In this blog post we […]
