Canadian Light Source Update
The Canadian Light Source (CLS) storage
ring has been operating routinely since commissioning
was completed in the spring of
2004. Beam currents up to 230 mA have been

achieved with the single superconducting RF cavity. With steady improvement beam lifetimes (1/e) of 10 hours at
170 mA and 0.25% coupling are now possible. In the last year the vertical tune was increased by 1 integer to produce
a smaller vertical beam size in the ID straight sections. This year the horizontal tune will be increased to reduce the
beam emittance. The vertical coupling has been reduced both globally and locally using a skew quadrupole response
technique. A wide range of photons energies are provided by an initial complement of five insertion devices (IDs) and
and two infrared (IR) ports. The 5 m straights have room for two IDs. The light cones from these IDs are separated by
about 1.5 mrad by "chicaning" the electron beam in the straights. To date two IDs have been installed in one straight
using the chicaning technique. As well, a superconducting wiggler and a in-vacuum undulator have been installed
and commissioned. An AppleII type elliptically polarizing undulator will be installed in April 2006.
Commissioning Results from the Injection System for the Australian Synchrotron Project
Danfysik has built a full-energy turnkey injection
system for the Australian Synchrotron.
The system consists of a 100 MeV
LINAC, a low-energy transfer beamline, a
full-energy booster and a high energy transfer
beamline. The booster synchrotron will

deliver a 3-GeV beam with an emittance of 33 nm. The lattice is designed to have many cells with combined-function
magnets (dipole, quadrupole and sextupole fields) in order to reach this very small emittance. The current in single −
and multi-bunch mode will be in excess of 0.5 and 5 mA, respectively. The repetition frequency will be 1 Hz. At the
time of writing this abstract, the LINAC beam has been injected into the low-energy transfer beamline. The project
is on schedule for delivery in April 2006. Results from the commissioning of the system will be presented together
with its performance.
Installation of the SOLEIL Accelerator Equipment: Booster, Storage Ring and Transfer
Lines
SOLEIL is a third generation Synchrotron radiation
Source, under construction in France J.C. Besson, J.-F. Lamarre (SOLEIL)
near Paris. The 357 m circumference storage
ring is mainly composed of (32 +1) dipoles, 160 quadrupoles, 120 sextupoles, 2 RF cryomodules, ∼ 200 vacuum
chambers, 6 injection equipment; 12 beamline front-ends and 4 insertion devices (initially). The 157 m circumference
Booster comprises 36 dipoles, 44 quadrupoles, 28 sextupoles, 1 RF cavity and 8 injection/extraction equipment.
Before the beginning of the Process installation, a general planning was established detailing the various stages of
the equipment installation and their assembly protocols before their on-site installation. In reality, many unknown
factors, delays on the buildings, delays on the equipment deliveries, technical problems encountered during the
construction, have constrained us to significantly and frequently amend and adapt this initial planning. Due to the
