Timing jitter studies of the SwissFEL Test Injector drive laser

Christoph Peter Hauri, Thomas Schietinger

To produce short X-ray pulses for SwissFEL(1), it is necessary to compress the electron bunches by a factor of 300, down to sub-fs for the attosecond operational modes. To achieve stable EEL output accurate timing of the initial electron injection at the m ...

Magnetic Model of the CERN Proton Synchrotron

Mariusz Juchno

In this thesis, we present development of the first magnetic model of the main Proton Synchrotron magnets. The operation of the machine and conducting research on increasing its performance require a significant amount of the magnetic field data for the op ...

Heat transfer through cable insulation of Nb-Ti superconducting magnets operating in He II

Pier Paolo Granieri

The operation of Nb–Ti superconducting magnets in He II relies on superfluidity to overcome the severe thermal barrier represented by the cable electrical insulation. In wrapped cable insulations, like those used for the main magnets of the Large Hadron Co ...

Design of a quench protection system for a coated conductor insert coil

Davide Uglietti

Coated conductors are promising material for the construction of high field magnets, but the slow propagation velocity of the normal zone makes the protection against quenches a critical issue. The quench protection system for a small insert coil under dev ...

Development of magnet technologies for HTS insert coils

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Rainer Wesche, Stephen Alfred March, Natalia Hanna Glowa

An existing Nb3Sn laboratory magnet generating a magnetic field of 12 T is intended to be upgraded to 16 T by means of the use of a high temperature superconductor (HTS) insert coil. An outline design of the HTS insert coil is presented. In the design, the ...

Ring magnets for magnetic beads trapping in a capillary

Hubert Girault, Anne-Laure Gassner

This paper introduces the concept of ring magnets for magnetic beads (MBs) trapping in a capillary. Such magnets enable an easy insertion of a capillary simply like a pearl on a string. With this system, high magnetic forces are obtained thanks to the prox ...

Cyclotron Designs for Ion Beam Therapy with Cyclinacs

Adriano Garonna

This thesis presents new superconducting compact (as opposed to separated-sector ) cyclotron designs for injection in CABOTO, a linac developed by the TERA Foundation delivering C6+/H2+ beams up to 400 MeV/u for ion beam therapy. This association of a vari ...

Magnetic Stationary Phases for Protein Adsorption

Anne-Laure Gassner

Magnetic beads (MB) have now proven to be a powerful tool in both research and biomedical applications. They are available in a wide range of sizes (from nm to several µm) and their surface can be modified with molecules having biological specificities and ...

TERA high gradient test program of RF cavities for medical linear accelerators

Adriano Garonna, Alberto Degiovanni

The scientific community and the medical industries are putting a considerable effort into the design of compact, reliable and cheap accelerators for hadrontherapy. Up to now only circular accelerators are used to deliver beams with energies suitable for t ...

Commissioning of Ramp and Squeeze at the LHC

Xavier Buffat, Jorg Wenninger

The energy ramp and the betatron squeeze at the CERN Large Hadron Collider (LHC) are particularly critical oper- ational phases that involve the manipulation of beams well above the safe limit for damage of accelerator components. In particular, the squeez ...
