JEMA SA will go to IPAC 2013 SHANGAI

From 12 to 16 May 2013, international particle accelerator conference


Early May, JEMA SA will visit CERN with a mission AWEX


JEMA SA participated in SLHiPP mtg 17-18 April 2013 in Louvain La Neuve organized by ESS / CERN / SCK-CEN


Early 2013, JEMA received the order of a modular power system (MOSAIC) to equip the new center beam line PT provided by IBA in Skandion at Upsala in Sweden These power (CIME-MOSAIC) provide the DC stabilized at 10 exp -4 dipoles and quadrupoles for equipping the line.


End of 2012, JEMA has been received by the CERN 2 Prototypes "modulators" of klystron to equip the new LINAC 4 at CERN in Geneva. Command, received LAL CNRS, Series 12 modulators is in process and they must be provided in the year 2013.

The Specialist in high performance DC power supplies and made to measure coil-based products.

For a number of decades, the company JEMA (also known under the name JEMA Elec) has been the uncontested Belgian specialist in high performance DC power supplies while remaining a benchmark in the production of made to measure coil-based dry and resistance transformers.

JEMA's high performance DC power supplies contribute daily to the treatment of hundreds of patients in numerous proton therapy treatment centres (cancer treatment by proton beams) in Europe, Asia and the United States.

Generally, and beyond a strong presence in the medical technology sector, JEMA direct current power supplies have applications in numerous sectors relying on particle accelerators (research laboratories, industrial or food sterilisation...) and in the most demanding industrial fields (thin film vapour deposition – pvd, polymerisation...)..

JEMA also designs and produces all types of rectifiers, battery chargers and cathodic protection, which are used in numerous sectors in infrastructure or industry. Furthermore, the experience acquired by JEMA since the end of the 1930s in the design and production of coil-based products allows us to respond to all your needs for one-off items and small or medium-sized series of dry transformers and resistances.

The design, production and tests for all these products are carried out at our premises located in the Einstein science park, Louvain-la-Neuve (Belgium), close to the university centre.

JEMA in partnership with its clients and suppliers, in collaboration with universities, industrial partners and with the assistance of the Walloon Region develops new products with increased performance and better adapted to the requirements of international and environmental standards.
