| TUPOMS006 | FILO: A New Application to Correct Optics in the ESRF-EBS Storage Ring | 1401 |
|
||
|
A new optics correction application (Fit and Improvement of Linear Optics, FILO) was designed and set in place for the ESRF-EBS storage ring. The widely used software LOCO* is not available at ESRF and despite a few trials to set it in operation, it has been decided to write a new code. The application is flexible, may be used via the control system simulators and is adapted to a user friendly operation thanks to a wizard mode. Some features of LOCO are copied over, some others are yet to be implemented. The measurement of on and off-energy response matrices using slow or fast steerers is integrated in the same application. Results obtained with this application are presented together with an overview of the future developments.

| TUPOMS008 | Lifetime Correction Using Fast-Off-Energy Response Matrix Measurements | 1409 |
|
||
|
Following the measurements done at MAX-IV * we try to exploit for the ESRF-EBS Storage Ring (SR) off-energy response matrix measurement for the optimization of Touschek lifetime. The measurements performed with fast AC steerers on- and off-energy are analyzed and fitted producing an effective model including quadrupole and sextupole errors. Several alternatives to extrapolate sextupoles strengths for correction are compared in terms of lifetime. For the time being none of the corrections could produce better lifetime than the existing empirically optimized set of sextupoles.

| TUPOMS009 | First Year of Operation of the ESRF-EBS Ligth Source | 1413 |
|
||
| The European Synchrotron Radiation Facility - Extremely Brilliant Source (ESRF-EBS) is a facility upgrade allowing its scientific users to take advantage of the first high-energy 4th generation light source. In December 2018, after 30 years of operation, the beam stopped for a 12-month shutdown to dismantle the old storage ring and to install the new X-ray source. On 25 August 2020, the user programme was restarted with beam parameters very close to nominal values. This paper reports on the present operation performance of the source, highlighting the ongoing and planned development. | ||

| THPOPT041 | Commissioning of New Kicker Power Supplies to Improve Injection Perturbations at the ESRF | 2683 |
|
||
| The ESRF-EBS storage ring resumed operation in 2020. Due to the reduced lifetime, top-up injection is required for all operation modes. Perturbations on the stored beam introduced by the pulsed injection elements represent a significant disturbance to the beam lines that need to run experiments across injection. In order to reduce these perturbation, new kicker power supplies with slower ramping times and better shot-to-shot reproducibility were developed at ESRF to improve the efficiency of the feed-forward compensation scheme. This paper reports on the design, commissioning and first experimental validation of these new power supplies. | ||
