It’s all about innovation
It is the ambition of our parent company, Danish Technological Institute, and its group of subsidiaries to be ‘best in class’, and the motto for the whole organization is ‘good is not enough’. This matches perfectly with what we have always strived for in Danfysik. Moreover, our customers from all over the world keep us on our toes, by requiring new developments, new solutions and new technologies for our products and systems. We often experience a demand for higher performances than what used to be good enough. Many of the cases in this news magazine are examples of this, e.g. the new integrated multimagnet technology for the new synchrotron light source MAX IV in Lund Sweden, fast injection and extraction systems for MedAustron in Austria, and high performance spectrometer systems for TRIUMF in BC Canada, just to mention a few. Solving the different challenges that this type of jobs offers, requires an innovative mindset in our organization, which we would never get on without in our business. – It’s all about innovation. Bjarne Roger Nielsen, CEO We thank our customers for showing their trust in Danfysik to develop, design and produce their demanding equipment.

Compound magnet structures for MAX IV
MAX-lab in Sweden has proposed the hitherto most ambitious design of third generation light sources for their new MAX IV synchrotron. In order to achieve the minimum electron beam emittance of a very compact 3 GeV machine with only 528 m circumference, the MAX IV lattice designers tried to distribute as many bending sections as possible around the ring. They found a solution choosing very compact achromatic magnet sections, by machining dipoles 3D design of the U3 compound magnet structure for the MAX IV facility in Lund, Sweden and quadrupoles into one yoke and by integrating higher multipole magnets into MAX IV plans to deliver the first beam the same compound magnet structure. Minimum electron beam to users in 2016.

Spin rotators for muon experiments at TRIUMF in Canada
Two Wien filters designed and manufactured at Danfysik for the M20 muon beamline at TRIUMF in Vancouver, Canada have been shipped recently after successful high voltage testing at our Taastrup premises.
The two, 1.5 m long electrodes of the electrostatic beam kicker carry a high voltage of +/-200 kV each and are integrated into a vacuum tank, which is fitted into a dipole magnet with a 560 mm wide pole gap. The effective length of the magnet is 1500 mm and the maximum field in the center of the magnet is 0.064 T.
Due to the crossed electrical and magnetic fields in the Wien filter, the spins of the muons rotate when the particles travel through the device, while the trajectory follows an undisturbed straight line for muons of the same energy. Muons are used as light hydrogen analogs for solid state studies and biological studies, or for probing magnetic properties of magnetic materials.
