Synchrotron Radiation Diagnostics for the NSLS Booster
We developed an optical diagnostics system
T.V. Shaftan, I. Pinayev (BNL)
for the NSLS booster-synchrotron utilizing
the synchrotron radiation from the dipole
magnet. MATLAB based software allows to study the electron beam properties along the energy ramp. The trajectory,
beam sizes and coupling at the different instants of time are retrieved from the analysis of the electron beam image.
In the paper we present the system layout, as well as experimental results and upgrade plans.

PRISM is a future muon source which would
provide high intense, monochromatic and
pure muon beams. In order to achieve such
muon beams we use a technique called Phase
Rotation using an FFAG ring (PRISM-FFAG). The PRISM-FFAG ring is now under construction in Osaka university.
The Commissioning will start in JFY 2007. In order to investigate the dynamical performances of the FFAG before the
actual commissioning, we propose a novel experimental method. The principle of the method and its application to
PRISM-FFAG will be described in this paper.
Beam-based Alignment Strategy for the Group Controlled Magnets System
N. Hayashi (JAEA/J-PARC) S. Lee, T. Toyama (KEK)
The beam based alignment of the beam position
monitor (BPM) becomes an important
tool to reduce the closed orbit distortion
(COD) in the recent accelerator. Normally, it requires the independent control of the quadrupole field. Changing
the current of a quadrupole magnet, one would find the unperturbed position. However, the J-PARC Rapid-
Cycling Synchrotron (RCS) has seven quadrupole families and only group of each family can be controlled simultaneously.
There is neither separate power supplies nor auxiliary coil windings on each individual magnet. A similar
alignment procedure is applicable for the coupled-controlled magnet system, but it becomes very complicated. For
the simplest case, three magnets grouped together, four different beam orbits have to be measured at three different
BPM locations. The method and some simulation results for J-PARC/RCS case will be presented in this report.
A Prototype of Residual Gas Ionization Profile Monitor for J-PARC RCS
A prototype of a residual gas ionization pro-
K. Satou, N. Hayashi (JAEA/J-PARC) S. Lee, T. Toyama (KEK) file monitor (IPM) for J-PARC RCS has been
developed. It consists of electrodes producing
electric field to collect ionized ions/electrons, MCP as a signal read-out device, an electron generator to evaluate
the gain balance of MCP channels, and a wiggler type magnet producing guiding field. The monitor has been installed
