Status of the ESRF EBS Storage Ring Engineering and Construction | |
|
||
| In the frame of its Extremely Brilliant Source (EBS) upgrade, the ESRF is preparing the replacement of its existing storage ring by a new ring based on a 7-bend achromat lattice enabling to reduce the electron beam horizontal emittance by a factor 30. The project involves challenging engineering requirements due to the large number of magnets, space constraints and specified geometrical precision. In order to validate the feasibility of this very compact assembly with real parts, a Mock-up of a complete EBS cell was assembled in 2017. The preparation of fully equipped girders with all components assembled, aligned and tested was started in October 2017 and is progressing as a rate of 3 per week. The main technical achievements and issues encountered during manufacturing of magnets, girders, chambers and absorbers will be presented, together with an outline of the planned dismantling and installation phases, scheduled from December 2018. This presentation is given on behalf of the ESRF EBS engineering team: J-C Biasci, J Borrel, T Brochard, F Cianciosi, D Coulon, Y Dabin, L Eybert, L Goirand, M Lesourd, N Louis, T Mairs, B Ogier, J Pasquaud, P Van Vaerenbergh, F Villar. | ||

| FROAMA07 | ESRF Double Crystal Monochromator Prototype Project | 440 |
|
||
| Spectroscopy beamlines at the ESRF are equipped with a generic model of double crystal monochromator, originally acquired in the 1990's. After over 15 years of continuous service, their conception, although pioneering 20 years ago, can no longer meet the challenge of present and future scientific goals in terms of position and angular stability, thermal stability, cooling system, vibration, control and feedback, particularly in view of the ESRF - EBS upgrade. Considering the above issues, a feasibility phase was launched to develop a prototype DCM dedicated to future spectroscopy applications at the ESRF. Specifications : derived from expected performance of the EBS upgrade and scientific objectives - are extremely challenging, especially in terms of mechanical and thermal stability and impose the adoption of several innovative design strategies. The prototype is currently in the assembly phase and tests of the complete system are planned before the end of 2018. An overview of the DCM prototype project will be given, including specifications, major design options implemented and various validated concepts. Current project status and first test results will also be presented. | ||
