1. Cryofree Superconducting Magnet System

A unique cryogen-free superconducting split-pair magnet system used for magnetic annealing applications in the semiconductor industry. Each superconducting coil half is a complete independent unit, conduction-cooled by a 4 Kelvin two-stage Gifford-McMahon (GM) cryocooler. The system also incorporates high-temperature superconductors (HTS), bismuth-based tapes for low thermal loss. The central magnetic field region is enhanced and shaped by external iron poles.

2. Semiconductor Magnetic Annealing Wafer Processing Magnet Systems

Everson Tesla teamed with a major semiconductor tool manufacturer to design and manufacture a complete magnetic annealing product for use in the manufacture of epitaxally produced magneto-resistive devices for read-write data storage heads. Under this work, Everson Tesla maintains responsibility for the Helmholtz magnet system as well as overall systems-integration responsibility for the magnet, power supply, precision oven, coolant system, vacuum system, and controls. Fully qualified systems are now installed and operational at several customer locations.

3. 5 Tesla Tilted Superconducting Magnet System for Stockholm University

For this project Everson Tesla was responsible for the design, fabrication, and testing of a complete 5T, 152 mm bore, superconducting magnet and cryogenic system. Major components included: closed-cycle refrigerator, 77 Kelvin shielded cryostat, high uniformity solenoid magnet, 45° angled beam tube, power supply, and instrumentation. This magnet system met or exceeded all customer performance requirements and has provided trouble-free operation for nearly three years.

4. Helium Dewar

An all-welded stainless steel liquid nitrogen shielded liquid helium dewar with a central top-loading exchange-gas sample insert.

5. Nitrogen Cryostat

A variable temperature liquid nitrogen cryostat. A rectangular tail allows the sample region to be located within the pole gaps of a resistive electromagnet to perform Hall effect experiments.

6. Edge Wound Rotor Coil

Everson Tesla Incorporated is a manufacturer of large edge wound rotor coils. Coils are cut, edge bent into "C" pieces, annealed, brazed and insulated turn-to-turn. Many of these rotor coils have punched or water-jet cut cooling vents.

7. Inductor Heater Coil

Everson Tesla Incorporated repairs large induction heater coils for the steel industry. Repairs include replacing some cooling circuit turns, re-insulation and varnish treatment. These coils are used in the process of melting steel.
