Whiffletree device for closure of flanged connections
The sealing of flanges is usually accomplished with a clamping force provided by multiple individual fasteners. In order to get a good seal, the individual fasteners must be tightened uniformly. This can be a sensitive and time-consuming process requiring high levels of workmanship, particularly for Ultra-High-Vacuum (UHV) and large flanges. When multiple...

Novel Radio Frequency Tuning of Dressed Multicell Cavities using Pressurized Balloons
Before a particle accelerator cavity is installed, it is carefully tested and tuned using an automated machine that grasps the edges of each cell to make small, precise adjustments. The process continues until the cavity is adjusted so that, once the cavity is up and running inside an accelerator, it’s in the shape to produce the perfect electric...

Channel Nut Tool
A project in Fermilab’s Main Injector tunnel required the insertion of 100s of “channel” nuts into a “Strut Channel.” For years, Fermilab engineers and technicians had to insert these nuts using their fingers, which is a repetitive and, eventually, painful process.
Fermilab’s Channel Nut Tool is used by screwing...

SRF e-beam accelerator for metal additive manufacturing
Electron beam additive manufacturing is a rapidly growing industry. Electron guns capable of reaching higher energies and higher average power can enable larger melt pools, higher production speed, and permit broader range of materials for metal additive applications. Such electron guns require technologies beyond those normally achieved with DC high...

Compact Nanofiber Electrospinner
The compact nanofiber production unit can produce a variety of ceramic and metallic nanofibers using very low power output and a low voltage direct current (DC) input. The unique dispenser, which uses a number of solid needles on a rotating helix instead of a syringe needle, facilitates mass production of large amounts of nanofibers in a short amount...

Redundant Single Event Upset Suppression System (SEUSS)
Electronic devices are getting smaller and more energy-efficient. This means they are more susceptible to single-event upsets- a malfunction caused by ionizing particles in the atmosphere interfering with electronic systems. The need increases as these devices get smaller, since particles that cause these upsets can even come from the packages that...

Particle Safe Vacuum Cart
Fermilab builds superconducting radiofrequency accelerators that require ultra-clean, ultra-high vacuum (UHV) systems. In order to protect these systems from irreparable damage, the various components must be cleaned, assembled, and installed using particle-free practices and leak-checked to a very high sensitivity.
The Fermilab Particle Safe Vacuum...

Railroad Crossing Ghost Train Generator (Instant Flagman)
Heavy or long wheel-based vehicles can become stuck or “high-centered” on railroad grade crossings, sometimes leading to highly destructive train accidents. An emergency device that “talks” directly to the railroad traffic signaling infrastructure could send instant red stop signals to trains within several miles of a blocked...

MARS15
MARS15 is a Monte Carlo code that simulates the passage of particles through matter. All types of particle interactions for hadrons, leptons, photons and heavy ions are included. Interaction and production cross-section modeling has been developed to match data, wherever such data is available, over a wide energy range. Accurate modeling is done in...
