| MOPAB133 | Optimisation of Electrical and Instrumentation Design for the Diamond Light Source DDBA Upgrade | 448 |
|
||
| In planning the upgrade of one cell of the Diamond Storage Ring, the DDBA upgrade, it was evident that the electrical installation and commissioning would contribute a significant component of the overall installation time. Given the pressures to minimise the shutdown length, the electrical and instrumentation design was optimised for time effective installation and commissioning. This paper outlines the electrical and instrumentation design for DDBA; explores the installation time determining issues and how these were addressed; and reports on the lessons learnt from the actual installation and commissioning process. | ||

| TUPAB116 | Insertion Devices at Diamond Light Source: A Retrospective Plus Future Developments | 1592 |
|
||
| 2017 marks the tenth year of Diamond operation, during which time all insertion device straights have been filled. Diamond Light Source is a third generation, 3 GeV facility that boasts 29 installed insertion devices. Most room temperature devices have been designed, manufactured and measured in-house, and progress has been made in structure design and control systems to ensure new devices continue to meet stringent requirements placed upon them. The ‘completion' of the storage ring is not, however, the end of activity for the ID group at Diamond, as beamlines map out potential upgrade paths to Cryogenic Permanent Magnet Undulators (CPMUs) and SuperConducting Undulators (SCUs). This paper traces the progress of ID design at Diamond, and maps out future projects such as the upgrade to CPMUs and the challenges of designing a fixed-gap mini-wiggler to replace a sextupole in the main storage ring lattice. | ||

| TUPIK115 | Control System Developments for the Diamond Light Source DDBA Upgrade | 1996 |
|
||
|
Upgrading one Double Bend Achromat cell to a Double Double Bend Achromat (DDBA) cell in the Diamond Light Source storage ring* necessitated a broad range of changes to the overall control system. These changes covered developments to the interface layer of the controls system to incorporate changes to the underlying instrumentation, associated development of user interface, changes to real-time feedback and feed-forward processes and to the online accelerator model. Given the pressures to minimise the shutdown length, the control system developments were optimised for time effective installation and commissioning. This paper outlines the control system developments for DDBA, the management process and lessons learnt from this process.

| WEPAB091 | Progress on Transparent Realignment of the Diamond Storage Ring | 2790 |
|
||
| The mechanical alignment of Diamond Storage Ring is achieved by means of a 5-axis motion system under remote control via the EPICS toolkit from the Diamond Control Room. We have completed the first phase of the realignment program meant to improve the mechanical alignment of the machine by carefully moving the magnet girders with a virtually zero impact on the associated beamlines, hence the name Transparent Realignment (TR). During this phase we have equipped and realigned 3 out of 24 cells, involving two beamlines. We have also tested and perfected the technique to execute a move with live beam and total remote control of the realignment process. The program has entered a second phase entailing the commissioning of 6 more cells. Details of tests on the machine are reported. | ||
