	Diamond Light Source: a 10-year view of the past and vision of the future R. P. Walker , R. Bartolini , C. Christou , P. Coll , M. P. Cox , M. T. Heron , J. Kay , V. C. Kempson , S. R. Milward , G. Rehm IPAC2017 DOI: 10.18429/JACoW-IPAC2017-WEPAB096 Open Access Show Abstract ▼ Abstract: Diamond Light Source has been in regular operation for users for 10 years and so it is an appropriate moment to review the successes and challenges of the past, and also consider the vision for the next 10 years.

Accelerator Physics	Long-term stability of the Diamond Light Source storage ring M Apollonio , Keith Baker , William Hoffman , James Kay , Vince Kempson , I Martin , Riccardo Bartolini IPAC2014 DOI: 10.18429/JACoW-IPAC2014-MOPRO099 Open Access Show Abstract ▼ Abstract: The Diamond storage ring has been in operation since January 2007. This paper summarises a number of measurements that have been made over that period to monitor the SR stability in height and position including general survey, Hydrostatic Levelling System (HLS), horizontal and vertical magnetic correction strengths as well as Radio Frequency (RF) that have given an indication of changing circumference.

Accelerator Physics	Enhancements to the Diamond Light Source pre-injector linac Chris Christou , Vince Kempson XXIV Linear Acceleration Conference (LINAC08) Show Abstract ▼ Abstract: Modifications have been made to the Diamond pre- injector linac to improve beam stability and to increase the scope of operation of the system. New modes of operation are described and RF stability studies are presented. Operational experience is summarised, and options for future development are considered.	Oct 2008
Accelerator Physics Controls Diagnostics Health Physics	Preparation for top-up operation at Diamond R. Walker , R. Bartolini , P. Bonner , F. Burge , Y. Chernousko , C. Christou , J. Dobbing , M. Heron , V. Kempson , G. Rehm , R. Rushton , S. Singleton , M. C. Wilson , I. Martin 11th European Particle Accelerator Conference (EPAC08) Show Abstract ▼ Abstract: It is planned to start top-up operation in Diamond in the near future. In this report we summarise the various activities that have led up to this point, including radiation safety considerations, preparation of hardware interlocks and control software, and injection optimisation.	Jun 2008
Accelerator Physics	Further optimisation of the Diamond Light Source injector Chris Christou , John Dobbing , Vince Kempson , Alun Morgan , Beni Singh , Steve Singleton 11th European Particle Accelerator Conference (EPAC08) Show Abstract ▼ Abstract: Optimisation of the Diamond Light Source injector has continued since user operation started in January 2007. Beam losses have been minimised by injector tuning and stabilisation, and high level software has been developed to characterise booster and injection parameters. Operation in top-up and single bunch storage ring fill modes are reported, and low-energy linac fault-mode studies are detailed.	Jun 2008
Accelerator Physics	Diamond Light Source: moving from commissioning to full machine operation Vince Kempson 11th biennial European Particle Accelerator Conference (EPAC08) Show Abstract ▼ Abstract: Diamond Light Source commenced routine operation in January 2007. Light to beamlines/users was provided for 3000 hours in 2007 increasing to 4000 hours during 2008. During shutdown periods insertion devices, front ends and beamlines have been and are being installed at a rate of approximately four per year. The evolution of the performance of the machine during this period is described and future developments are discussed.	Jun 2008
Accelerator Physics	Operation of the Diamond Light Source injector Chris Christou , Vince Kempson 2007 IEEE Particle Accelerator Conference (PAC) DOI: 10.1109/PAC.2007.4440999 Show Abstract ▼ Abstract: The Diamond Light Source (DLS) injector consists of a 100 MeV pre-injector linac and a 3GeV full energy booster. The injector system has been reliably providing beam to the storage ring since September 2006 in both multibunch and single bunch mode, at 5 Hz repetition rate. Single bunch and hybrid modes are being developed now for users later this year. Single bunch purity has been measured in the storage ring to be better than 0.1%. The timing system can be controlled to allow a wide range of filling patterns, including complete ring fill in both single and multibunch mode, and hybrid fills with individual single bunches placed in gaps between continous bunch trains. Top-up operation is envisaged for user operation in the future, and trials are underway to ensure safe and efficient running in this mode.	Jun 2007
Magnets Power Supplies	Pulsed magnets and pulser units for the booster and storage ring of the Diamond Light Source J. A. Dobbing , G. M. A. Duller , N. Hauge , G. Hilleke , C. Hansen , V. C. Kempson Tenth European Particle Accelerator Conference (EPAC '06) Show Abstract ▼ Abstract: The Diamond booster and storage ring facility has ten pulsed magnet systems, five for the booster (injection and extraction) and five for the storage ring (injection septum and four bump kickers). Each has its own specific requirements although commonality of design has been adopted where possible. Design and construction principles and results of magnet and pulser testing are discussed as is the first use of the magnet systems during beam commissioning.	Jun 2006
Magnets	Magnets for the 3 Gev booster synchrotron for the Diamond Light Source S. Mhaskar , C. P. Bailey , V. Kempson , N. Hauge , F. Bodker , L. Helmersen , G. M. A. Duller Tenth European Particle Accelerator Conference (EPAC '06) Show Abstract ▼ Abstract: The Diamond Booster is a full energy injector for the Diamond Storage Ring, designed to accelerate an electron beam from 100 MeV to 3 GeV with a 5 Hz repetition rate. This paper describes the main features of the magnetic designs and the magnetic measurements results for the booster magnets which have now been delivered and installed at Diamond.	Jun 2006
Accelerator Physics	Commisionning of the booster synchrotron for the Diamond Light Source Vince Kempson , Riccardo Bartolini , Chris Christou , John Dobbing , Graham Duller , Mark Heron , James Rowland , Beni Singh , Guenther Rehm Tenth European Particle Accelerator Conference (EPAC '06) Show Abstract ▼ Abstract: The Diamond booster synchrotron has been in construction through 2005 and its various subsystems were installed and commissioned independently such as magnets, power converters, vacuum system, RF, cabling cooling and safety systems. Since December 2005 the booster has been brought up to specification as the subsystems and utilities became available and has performed excellently as an injector for the initial trials of the Diamond storage ring in May 2006.
