The detailed design study phase of the SPIRAL2 project has been launched since beginning of 2003. The aim of this facility is to produce rare ion beams, using a Uranium carbide target fission process, based on a fission rate of 1013 to 1014 fissions/s. The driver accelerator accelerates a 5 mA deuteron beam up to 20 MeV/u, impinging on a carbon converter to produce the neutrons necessary to the fission process. It has also to accelerate q/A=1/3 heavy ions, to energies between 0.75 and 14.5 MeV/A for different types of nuclear and non-nuclear physics experiments. The accelerator, based on a RFQ followed by an independently phased superconducting cavity linac with warm focusing sections, is under design. This paper presents the reference design chosen for SPIRAL2 driver accelerator and gives the design status of the different components: Sources, RFQ, Superconducting linac, RF Systems, Cryogenics, Mechanical layout.

Gamma and X-rays Production for Experiments at ELSA Facility

The ELSA facility is a high brightness 18 MeV electron source dedicated to electron radiation, gamma-rays and picosecond hard and soft X-rays. It consists of a 144 MHz RF photoinjector producing short bunches which are further accelerated to a final energy varying from 2 to 18 MeV thanks to three 433 MHz RF cavities. Former beam compression design used a half turn magnet compressor system. It has been recently replaced by a double alpha magnet compressor. Electron beams are now delivered to a new experimental room. We present the new panel of interests offered by this facility in term of gamma-ray and X-ray production.

Five accelerating modules are installed in the VUV FEL linac so far. This includes 40 high power couplers connected to the superconducting cavities, eight in every module. All of them are processed and operated up to the cavity performance limits. The coupler processing procedure is described. The performance in relation to the test results on the coupler test stands are discussed.

The photo injector test facility at DESY Zeuthen successfully concluded it's first phase of operation in November 2003 (PITZ1). After a complete characterization of the injector, the gun has been delivered to Hamburg and has already been taken into operation on the VUV-FEL. The measurement program for the year 2003 included RF commissioning, emittance studies, momentum and bunch length measurements, and studies of the influence of the drive laser parameters. We provide an overview on the latest achievements in all of these topics.

We report on our present progress toward the investigation on the generation of flat beam from an incoming angular-momentum-dominated beam, along with the associated diagnostics development. We focus on the evolution of the four-dimensional beam matrix upstream and downstream of the round-to-flat beam transformer. Finally we compare our latest experimental results with numerical and analytical models.

Status of the J-PARC Linac, Initial Results and Upgrade Plan

The J-PARC linac building will be completed by March, 2005, when the installation of the linac components will start. On the other hand, the front end linac, comprising the 3 MeV RFQ linac, the MEBT with the beam chopper, and the 20 MeV DTL first tank, is under beam commissioning in the KEK site. A peak current of 30 mA, which is enough for the 0.6 MW operation of Rapid-Cycling Synchrotron (RCS), was accelerated up to 20 MeV on the second day of the beam commissioning, last November. The detailed study of the system is under way, including the stability test of many components. The front end linac will be shipped to the JAERI Tokai site after the building completion there. The beam commissioning of the 181 MeV linac will start in September 2006, that of the 3 GeV RCS in May, 2007, and that of the 50 GeV Main Synchrotron (MR) in November 2007. The beam acceleration in the MR will be done by March, 2008. It is strongly recommended by the government committee that the upgrade to the 400 MeV linac should start immediately after the completion of the above accelerator system, that is, in April 2008, with the period of three years, aiming the 1 MeV RCS beam power.

Status of the SNS Linac: An Overview

The Spallation Neutron Source SNS is a second generation pulsed neutron source and under construction at Oak Ridge National Laboratory. The SNS is funded by the U.S. Department of Energy?s Office of Basic energy Sciences and is dedicated to the study of the structure and dynamics of materials by neutron scattering. A collaboration composed of six national laboratories (ANL, BNL, TJNAF, LANL, LBNL, ORNL) is responsible for the design and construction of the various subsystems. With the official start in October 1998, the operation of the facility will begin in 2006 and deliver a 1.0 GeV, 1.4 MW proton beam with a pulse length of approximately 700 nanoseconds on a liquid mercury target. The multi-lab collaboration allowed access to a large variety of expertise in order to enhance the delivered beam power by almost an order of magnitude compared to existing neutron facilities. The SNS linac consists of a combination of room temperature and superconducting structures and will be the first pulsed high power sc linac in the world. The challenges and the achievements will be described in the paper.
SNS is managed by UT-Battelle, LLC, under contract DE-AC05-00OR22725 for the U.S. Department of Energy. SNS is a partnership of six national laboratories: Argonne, Brookhaven, Jefferson, Lawrence Berkeley, Los Alamos and Oak Ridge.

The Physics Perspectives at the Future Accelerator Facility FAIR
|
858 |
| |
|
|
| |
The physics perspective of the approved future international accelerator Facility for Anti-proton and Ion Research (FAIR) near Darmstadt, Germany will be outlined. The physics programme will comprise many body aspects of matter ranging from macroscopic system like highly correlated plasmas down to the properties of baryons and nuclear matter at high baryon densities. Through fragmentation of intense ion beams investigations with beams of short-lived radioactive nuclei far from stability will be possible. The addressed physics questions concern nuclear structure at the drip-lines, areas of astrophysics and nucleo-synthesis in supernovae and other stellar processes, as well as tests of fundamental symmetry. The structure of baryons and their limits of their existence is the interest of the two large experimental set-ups PANDA and CBM. Finally QED will be studied in extremely strong field effects and also the interaction of ions with matter. The future facility will feature a double-ring synchrotron SIS100/300 and a system of associated storage rings for beam collection, cooling, phase space optimisation and experimentation.
