Design and Construction of the PEFP Timing System for a 20MeV Proton Beam
The timing system of the PEFP requires synchronization
for the accelerator and for the
multipurpose beam line. The system is based
on an event distribution system that broad-

casts the timing information globally to all the equipment. Fast I/O hardware of the timing system is to distribute
appropriate timing signals to accelerator systems, including the Injector, RFQ, DTL, and user’s facilities. Signals to be
distributed include the synchronized pulse triggers and event information of RF system and switching magnet power
supplies for the 20MeV proton beam extraction.
High Power Cavity Combiner for RF Amplifiers
A new approach of RF power combination
has been developed for the ALBA Storage
Ring RF system: a three-port high power
Cavity Combiner (CaCo). A prototype has

been successfully built and tested in Thales Electron Devices, Thonon, France. The final goal is to combine the power
of two 80 kW IOTs at 500 MHz in order to provide a total output power of 160 kW. In this paper, a summary of
the analytical and simulation analysis of the expected behaviour is given. In basis of that, the decided geometric
constraints and the final design configuration chosen for the prototype production are explained. Low power test
results and matching, and finally the high power test performances, are shown. As a conclusion, the RF system of the
ALBA Storage Ring will incorporate the CaCo concept to obtain the needed power per cavity from the combination
of two IOTs.
Equipment for Tunnel Installation of Main and Insertion LHC Cryo-magnets
The installation of about 1700 superconducting
dipoles and quadrupoles in the Large
Hadron Collider (LHC) is now well underway.
The transport and installation of the

LHC cryo-magnets in the LEP tunnels originally designed for smaller, lighter LEP magnets have required development
of completely new handling solutions. The severe space constraints combined with the long, heavy loads have
meant that solutions had to be very sophisticated. The paper describes the procedure of the installation of the main
cryo-magnets in the arc as well as the more specific insertion cryo-magnets. The logistics for the handling and transport
are monitored with tri-axial acceleration monitoring devices that are installed on each cryo-magnet to ensure
their mechanical and geometric integrity. These dynamic results are commented. The paper includes conclusions
and some lessons learned.
