SYNCHROCYCLOTRON PRELIMINARY DESIGN FOR A DUAL HADRONTHERAPY CENTER

Adriano Garonna

The Italian research foundation TERA has proposed an innovative accelerator solution, called “Cyclinac” [1], dedicated to hadrontherapy, the technique of tumor radiotherapy which employs ion beams, in particular protons and carbon ions. It is composed of a ...

Accelerators for hadrontherapy: From Lawrence cyclotrons to linacs

Adriano Garonna, Alberto Degiovanni

Hadrontherapy with protons and carbon ions is a fast developing methodology in radiation oncology. The accelerators used and planned for this purpose are reviewed starting from the cyclotrons used in the thirties. As discussed in the first part of this pap ...

High-Gradient Test of a 3 GHz Single-Cell Cavity

Adriano Garonna

Proton and carbon ion beams present advantageous depth-dose distributions with respect to X-rays. Carbon ions allow a better control of "radioresistant" tumours due to their higher biological response. For deep-seated tumours prot ...

Radiation protection studies for CERN Linac4/SPL accelerator complex

Egidio Mauro

CERN is presently designing a new chain of accelerators to replace the present Proton Synchrotron (PS) complex: a 160 MeV room-temperature H- linac (Linac4) to replace the present 50 MeV proton linac injector, a 3.5 GeV Superconducting Proton Linac (SPL) t ...

Principe d'alimentation par convertisseurs multiniveaux à stockage intégré

Claude Fahrni

Facilities operating in cycles, such as particles accelerators, require pulsed power. Directly drawing this pulsed power from the industrial network is generally not acceptable. A system with a local energy storage system lessens the impact on the network. ...

A Multilevel Power Converter with Integrated Storage for Particle Accelerators

Alfred Rufer

The PS accelerator (Proton-Synchrotron) at CERN (European Organization for Nuclear Research) is composed of one hundred magnets connected in series. During a cycle of 2.4 seconds, the active power at the magnets terminals varies from plus to minus 40 MW. A ...

Magnetic susceptibility measurement and modelisation of a novel compound

Bastien Dalla Piazza

We study the magnetic susceptibility of the novel metal-organic framework [Cu3(mu3O)(mu3trz)3(OH)(H2O)6. The magnetic susceptibility is measured using a SQUID magnetometer. Exact diagonnalization and mean Field theory are then used in an attempt to Fit the ...

Optics design and performance of an ultra-low emittance damping ring for the compact linear collider

A high-energy (0.5-3.0 TeV centre of mass) electron-positron Compact Linear Collider (CLIC) is being studied at CERN as a new physics facility. The design study has been optimized for 3 TeV centre-of-mass energy. Intense bunches injected into the main lina ...

Nanoscale superparamagnetic composite particles for biomedical applications

Mathieu Chastellain

The present thesis report deals about the material scientists contribution to the interdisciplinary European project "MAGNANOMED" involving people having very different backgrounds (physicist, chemists, biochemists, veterinary surgeons, ...). The work carr ...

Flexible bearings for high precision mechanisms in accelerator facilities

Simon Nessim Henein

While in conventional mechanical bearings motion is obtained by sliding or rolling between solid bodies with the resulting mechanical non-linearities, flexible bearings rely on the elastic properties of matter allowing several advantages to be obtained. Co ...
