HIGH-GRADIENT TEST OF A 3 GHz SINGLE-CELL CAVITY

Adriano Garonna, Alberto Degiovanni

Accelerators can be used for hadrontherapy, a cancer treatment in which the patient is irradiated with hadron beams. For this purpose, the Italian foundation TERA proposes the “cyclinac”, composed of a high-frequency linac which boosts the hadrons accelera ...

MEASURING THE BUNCH FREQUENCY MULTIPLICATION AT CTF3

Daniel Egger

The CLIC Test Facility 3 (CTF3) is being built and commissioned by an international collaboration to test the feasibility of the proposed Compact Linear Collider (CLIC) drive beam generation scheme. Central to this scheme is the use of RF deflectors to inj ...

Update of the SPS Impedance Model

Nicolas Frank Mounet, Carlo Zannini, Benoît Salvant

The beam coupling impedance of the CERN SPS is expected to be one of the limitations to an intensity upgrade of the LHC complex. In order to be able to reduce the SPS impedance, its main contributors need to be identified. An impedance model for the SPS ha ...

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 ...

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 ...

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 ...

A 120 mm Bore Quadrupole for the Phase I LHC Upgrade

Pier Paolo Granieri

The phase I LHC upgrade foresees the installation of a new final focusing for the high luminosity experiences in order to be able to focus the beams in the interaction points to ß* 0.25 cm. Key element of this upgrade is a large bore (120 mm) superconducti ...

A PROOF-OF-PRINCIPLE ECHO-ENABLED HARMONIC GENERATION EXPERIMENT AT SLAC

Pierre-Louis Pernet

In this paper we describe the technical design of an ongoing proof-of-principle echo-enabled harmonic generation (EEHG) experiment at the Next Linear Collider Test Accelerator (NLCTA) at SLAC.We present the design considerations and the technical details o ...

MULTI-BUNCH EFFECT OF RESISTIVEWALL IN THE CLIC BDS

Nicolas Frank Mounet, Raphaël Mutzner

Wake fields in the CLIC Beam Delivery System (BDS) can cause severe single or multi-bunch effects leading to luminosity loss. The main contributors in the BDS are geometric and resistive wall wake fields of the collimators and resistive wall wakes of the b ...

Measuring the Longitudinal Bunch Profile at CTF3

Daniel Egger

The CLIC Test Facility 3 (CTF3) is being built and commissioned by an international collaboration in order to test the feasibility of the proposed Compact Linear Collider (CLIC) two-beam acceleration scheme. The monitoring and ...
