Lake Shore Janis Superconducting Magnet Systems
Superconducting Magnet Systems
With over four decades of experience and a worldwide installation base, Lake Shore (Environment by Janis) is a recognised leader in the design and manufacture of superconducting magnet systems. Janis’ renowned SuperVariTemp insert operates from 1.5 K to 325 K, and is featured in the SuperVariMag, OptiMag and SuperOptiMag systems and is also available as an independent insert for use with existing magnets. Lake Shore also offers a variety of superconducting magnet systems that offer a room temperature bore (with inserts that reach 800 K), along with a variety of other systems that are designed for specific applications. These state of the art systems feature integrated designs for the cryostat, magnet, temperature controller and programmable power supply, together with a complete line of ancillary equipment. Their approach to superconducting magnet system design provides a variety of technical and cost benefits.
By maintaining flexibility over the specification and integration of the magnet, electronics, temperature controller, and cryostat, Lake Shore is able to offer magnet systems with performance characteristics tailored to individual experimental and budgetary requirements.
