In the framework of the upgrade of the LHC machine, new Superconducting Links are being developed for the feeding of the LHC superconducting magnets. The electrical lines, which are made from High Temperature Superconductors, contain tens of cables feeding different electrical circuits and transfer all together DC currents of more than 150 kA. The required length of the cables and the current...

In collaboration with Forschungszentrum Jülich (FZJ) the Helmholtzinstitut Mainz (HIM) pursues the design of an 8MV electron cooler. In the present concept, about 1 MW of electrical power would be needed to drive the compressor-system for turbogenerators which use the insulating gas (sulphur hexafluoride, SF6) as medium. We propose to generate the necessary flow of pressurized SF6 by ...

In J-PARC Main Ring (MR), the upgrade toward megawatt beam intensity is scheduled. To achieve megawatt beam, we need to increase the repetition rate of the accelerator from 0.42 Hz to 1 Hz. In this case, the total power variation in main grid is up to 100 MVA. This is because the magnets in MR should be driven much faster in 1 Hz operation. However, such power variation is not allowed by the...

Vacuum is the best thermal insulator made available by Nature. Thanks to the reduced thermal losses provided by vacuum, the SRB solar thermal collector may reach temperatures up to 400°C without the help of light focussing mirrors. This is a very important feature for Central Europe, where diffuse light, which cannot be focused, may exceed 50% of the available solar power.
The vacuum inside...
