We are excited to announce that JEMA has won the tender contract for CNRS France for the realization, delivery and commissioning of 33 power converters for the proton LINAC of Germany’s FAIR international accelerator facility.
FAIR stands for Facility for Antiproton and Ion Research. This accelerator facility provides beams of antiprotons and ions with highest intensities, energies and power in brilliant quality. FAIR is a multipurpose and worldwide unique accelerator facility allowing a large variety of unprecedented fore-front researches in physics and applied science. More info here.
Today, a new part of the facility is being built including, among other things, a p-LINAC.
A significant part of the experimental program at FAIR is dedicated to antiproton physics. Antiprotons in FAIR will be used for two types of experiments:
In the FAIR Modularized Start Version (MSV) only PANDA is foreseen as a user of antiprotons. The antiproton will be produced by shooting a short intense proton bunch with 28 GeV on a copper target.
A dedicated proton LINAC of 68 MeV final energy, SIS18 is used for acceleration to 4 GeV and SIS100 for an acceleration to 27.6 GeV. The proton beam is foreseen to be generated in an ECR type proton source and a proton current of up to 100 mA can be extracted at 95 keV.
The subsequent Low Energy Beam Transport (LEBT) is based on two-solenoid magnetic focusing and provides the required separation of H3+, H2+, and H2 fractions from the proton beam. Bunching and acceleration to 3.0 MeV will be accomplished in a ladder type 4-rod RFQ preceded by an electrostatic chopper.
JEMA will provide a total of 33 power converters that will power the different magnets of the new FAIR proton LINAC facility: 25 power converters will be used for powering quadrupole magnets and 8 for powering the steerer magnets.
More precisely, we will provide 17 cabinets including:
All 33 converters providing 1x10-4 long term stability and precision. Each power converter will be designed according to customer requirements.
