| MOPRO099 | Long-term Stability of the Diamond Light Source Storage Ring | 319 |
|
||
| The Diamond Storage Ring (SR) 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 magnet corrector strengths as well as Radio Frequency (RF) measurements that have given an indication of changing circumference. | ||

| MOPRO100 | Engineering Integration Constraints on the Beam Physics Optimisation of the DDBA Lattice for Diamond | 322 |
|
||
| The design and optimisation of the new DDBA lattice for Diamond has been performed taking fully into account, from the early stages, the geometry and the engineering integration constraints. In this paper we review the evolution of the DDBA cell, the rationale for its modification and the optimisation strategy used. | ||

| MOPRO101 | Transparent Re-alignment of the Diamond Storage Ring | 325 |
|
||
| 72 out of the 74 girders on which the Diamond Storage Ring magnets are mounted, can in principle be moved along 5 degrees of freedom (sway, heave, yaw,pitch, roll) potentially allowing a thorough re-alignment of the machine. Previously conducted tests improved our knowledge of the system both in terms of simulations and comprehension of the control system we rely upon. In this report we present the results of more detailed tests which now give us full confidence in our ability to predict the results of any given set of girder moves. We also discuss possible ways of increasing the speed of the procedure, and a strategy to mitigate the impact of girder moves involving nearby beam lines. | ||

| MOPRO103 | The Double-double Bend Achromat (DDBA) Lattice Modification for the Diamond Storage Ring | 331 |
|
||
|
The concept of converting individual cells of the Diamond Double Bend Achromat (DBA) lattice into a modified 4-bend achromat with a new straight section for insertion devices (IDs) in the middle of the arc, grew out of earlier studies of low emittance MBA lattices*, and was motivated by the need for additional ID straight sections, since all of the 22 ID straight sections in the Diamond storage ring are either occupied or have been allocated to future beamlines. Such a modification effectively replaces each DBA cell with two new DBA cells, hence the term Double-DBA or DDBA has come to be used for the project. Since the tangent point for bending magnet beamlines lies close to the start of the second dipole in the original DBA, this allows unused exit ports and spaces on the experimental hall which are available for future bending magnet beamlines to be used for higher performance ID beamlines. In this report we present an overview of the status of the project, the various accelerator physics and engineering studies that have been carried out, and plans for the implementation of one or two DDBA cells in Diamond.
