Commissioning of the Diamond Pre-injector Linac
Commissioning of the linac for the Diamond
C. Christou, V.C. Kempson (Diamond) K. Dunkel (ACCEL) Light Source (DLS) was completed in October
2005. The linac was supplied by Accel
Instruments as a complete system, with DLS providing beam diagnostics, beam analysis software, control system
hardware and standard vacuum components. Much of the beam analysis was carried out using the first part of the
Linac to Booster transfer line (LTB), which was designed and built by DLS. Operation of the linac and LTB at 100 MeV
in long-pulse and short-pulse modes of operation was demonstrated, and all operational parameters were measured
to be within specification.
RF Distribution System of the Diamond Master Oscillator

A modular RF distribution system has been
designed and built at Diamond Light Source
to distribute the master oscillator (MO) signal.
The system will deliver a low noise,
phase stable 500 MHz signal to multiple points of use around the synchrotron facility. Providing phase stability
and preserving noise performance over the distances required (up to 300m) have been the main design challenges.
A modular approach provides future flexibility, and this paper describes each component, outlining design choices,
components used, construction details and test results.
Design, Manufacturing and Integration of LHC Cryostat Components: an Example of a
Collaboration between CERN and Industry

The components for the LHC cryostats and
interconnections are supplied by the European
industry. The manufacturing, assembly
and testing of these components in accor-
dance with CERN technical specifications require a close collaboration and dedicated approach from the suppliers.
This paper presents the different phases of design, manufacturing, testing and integration of four LHC cryostat
components supplied by RIAL Vacuum (Parma, Italy), including 108 insulation vacuum barriers, 482 cold-mass extension
tubes, 115 cryostat vacuum vessel jumper elbows and 10800 interconnection sleeves. The Quality Assurance
Plan, which the four projects have in common, is outlined. The components are all leak-tight thin stainless steel
assemblies (< 10 -8 mbar l/s), most of them operating at cryogenic temperature (2 K), however each having specific
requirements. Therefore the peculiarities of each component are presented with respect to manufacturing, assembly
and testing. These components are being integrated at CERN into the LHC cryostats and interconnections, which
allowed validating the design and production quality. The major improvements and difficulties will be discussed.
