The Radioactive Beam Experiment (REX-ISOLDE) [1,2] is a pilot experiment at ISOLDE (CERN) testing the new concept of post acceleration of radioactive ion beams by using charge breeding of the ions in a high charge state ion source and the efficient acceleration of the highly charged ions in a short LINAC using modern ion accelerator structures. In order to prepare the ions for the experiments s...

In light of the SPEAR3 upgrade project where the goal is to store up to 500 mA of beam current at 3.0 GeV beam energy, the injector RF gun and linac performance must be optimised in terms of reliability and injection rate. The basic linac system layout has not been changed for the last ten years of operation. A thermionic1.5-cell standing wave RF gun is the source of bunched beams at 10 Hz. An ...

In 2014 a new vertical flight path was installed at the neutron time-of-flight facility, n TOF, at CERN. The beam line optimization of this second experimental area (EAR2) was performed by FLUKA simulations with a detailed model of the facility, including the spallation target, neutron beam line, magnet, collimators and beam dump. The beam profile as well as neutron and gamma fluxes were calcul...

The measurement of the transverse beam emittance is essential in any particle accelerator. This paper describes the problems of transverse emittance measurement for the new H LINAC being built at CERN as a replacement of the existing proton LINAC.

Progress of the shielding calculation of the Super-FRS is reported here. At least as important as the shielding of the target area is the determination of the shielding in the region of the first dipoles as the part of the primary beam that will not interact in the target will be stopped here. The Monte-Carlo-method with FLUKA [1] used for the shielding assessment here has already been describe...

The Linac Coherent Light Source (LCLS) at SLAC is being designed to produce intense, coherent 0.15-nm x-rays. These x-rays will be produced by a single pass of a 15-GeV bunched electron beam through a long undulator. Nominally, the bunches have a charge of 1 nC, normalized transverse emittances of less than 1.5π mm-mr and an rms bunch length of 20 μm. The electron beam will be produced using th...

Electron accelerators from 500 keV to 10 MeV energy are employed for surface irradiation, food preservation, medical sterilization, cargo scanning and other industrial products. At EBC, a 10 MeV Linac has been indigenously developed and is operational for radiation processing. This is an on-axis coupled cavity standing wave type of RF linac operating with 50-70 keV electron gun having LaB6 cath...

This note describes how a future Fermilab proton driver [1] based on TESLA superconducting linac modules can perform as both the source of protons to produce the muons and as the accelerator of the muons to be used for a neutrino factory or muon collider. Recent advances in muon cooling [2] have the promise of muon emittances that are compatible with the 1300 MHz accelerating structures that ar...

Introduction: Nowadays, the use of heavy ion beams in cancer therapy have been developed worldwide.   Materials and Methods: It requires accurate understanding of the complex processes of ion interaction with matter, as it is the calculation the relative dose & range of these ions in matter. In the present study we used FLUKA as a numerical Monte Carlo simula...

The Linac Coherent Light Source (LCLS) is a SASE free electron laser using the last 1/3 of the SLAC two mile linac to produce 1.5 to 15 angstrom x-rays in a 100 meter long undulator for use in a variety of x-ray science experiments. In order to satisfy the demanding electron beam requirements, a new 135 MeV photo-injector will be built in an existing, off-axis vault at the 2/3 point of the main...
