During his PhD in Medical Physics at the University of Sheffield and Royal Hallamshire Hospital, Sheffield, UK, Reza Jalinous designed and made the first magnetic stimulator used for transcranial brain stimulation.


The technology behind magnetic brain stimulation was then licensed to Novametrix, Inc. Wallingford, CT,  where Reza Jalinous designed the Magstim Model 200 now mentioned in 1,000s of publications.


In 1990, Robin Lewis, Reza Jalinous and Roy Hovey founded Magstim Company Limited in Wales, UK. After twenty five years as an executive board member at Magstim Co. the company was sold to Telegraph Hill Partners in San Francisco. To this date Magstim Company remains a leading supplier of magnetic stimulation products for both research and for the treatment of depression with offices in Wales and the USA.

Jaltron LLC currently specializes in the custom design of non-standard coils and accessories for connection to magnetic stimulator manufacturers such as Magstim Company. Jaltron Coils is a division of Jaltron LLC.​
