2.9 GeV turn-key booster for the Canadian Light Source, Saskatoon, Canada

Project start 2001. Project completion 2002.

The 2.9 GeV booster for the Canadian Light Source

The 2.9 GeV booster synchrotron is the full-energy electron injector for the 2.9 GeV Canadian Light Source (CLS) at the University of Saskatchewan, Saskatoon, Canada. After injection of a 250 MeV electron beam from the upgraded Saskatchewan Accelerator Laboratory linac, the booster synchrotron accelerate a beam current of more than 10 mA up to a maximum energy of 2.9 GeV and subsequently extract the beam for injection into the CLS storage ring; a sequence which is repeated with a frequency of 1 Hz. The complete booster synchrotron is designed and constructed by Danfysik based on an initial conceptual design by CLS.

The booster synchrotron is divided into 14 girders with one dipole magnet and one quadrupole magnet, and 6 girders with one dipole magnet and two quadrupole magnets. Prior to the installation, the vacuum system and all the magnetic elements were pre-assembled and aligned on the girders and the girders were shipped to CLS as complete units. At CLS each girder could be unpacked, moved to its final position in the booster tunnel on a transport cart, located on two columns, and rough aligned within ±1 mm in only two hours. As a consequence all magnetic elements were installed and rough aligned at CLS within only three weeks. Subsequently, the vacuum systems of the girders were interconnected and the girders were connected to the local infrastructure.

Since the acceptance test in September 2002 no major changes has been made to the booster. It reliably injects a beam current of 20-25 mA at 2.9 GeV into the storage ring. The booster operates without the bumper magnets, and it is easy to extract the beam from the un-bumped orbit. The orbit correctors are only used to improve the injection efficiency and are not ramped. The beam from the booster is easily transported to the storage ring and injected into the ring with little or no beam loses in the transport line.
