| TUPP004 | Evolution and Status of the Electronic Logbooks at the ESRF | 1532 |
|
||
| In 2004 the ESRF moved to electronic logbooks. Such logbooks should be configurable enough to be used in several situations: document management, exchange of technical information and, in the Control Room, as a powerful tool for storing and retrieving information at a glance. The St James software company developed such a product which met our constraints and which is easy to configure. Moreover, this product can be tailored and evolved with time by its users and allows automatic access to control system parameters. After gaining experience with several logbooks using the old version 4 system, a new more user-friendly version which offers extensive customisation possibilities has been launched. This new version, J5, has already been interfaced to the ESRF control system (Tango) through a Python binding. This allows automatic triggering of records on specific events and the generation of automatic reports from the history database system. J5 can use an LDAP server for security management. | ||
| TUPP011 | The ESRF Temperature Monitoring System from an Operational Point of View | 1547 |
|

| The vacuum control system of the ESRF electron Storage Ring (SR) is in operation since more than ten years now. Apart from difficulties to have appropriate support for the old system, we start facing problems of aging and obsolescence. We have been reviewing our philosophy of data acquisition and remote control in order to upgrade our systems with state of the art technology by taking into account our operational experience. We have installed shielded "intelligent" devices inside the SR and took advantage of the latest developments linked to new communication technologies and standards, such as TCP/IP MODbus protocol and WEB server based instrument control. This presentation outlines our present work dedicated to the ESRF temperature acquisition system based on Programmable Logic Controllers (PLC), and new developments regarding the user interface in the control room. Several examples show the importance of surveying the temperatures in order to identify various mechanical or operational problems which allow us to anticipate later failures and provide us with an additional machine diagnostic tool. | ||
| TUPP012 | Presentation of the New ESRF Vacuum Control Applications from an Operational Point of View | 1550 |
|
||
| The ESRF is in operation since more than ten years. Due to the aging vacuum system, we are faced to different kinds of failures such as air or water leaks, overheating of RF-liners or poor chamber alignment. In order to anticipate these failures and therefore reduce down times, we started to develop new diagnostic tools which allow us to detect much faster and with more precision any possible failures or malfunctioning of our vacuum system. Also driven by the increase of machine performances and the continuous vacuum installations, we search for new tools to safely commission such upgrades. This paper outlines our work on the development of a new vacuum user interface, which not simply reflects the actual status of our vacuum system, but which also provides us with a dynamic survey of computed vacuum signals highlighting unusual vacuum behaviours. | ||
| WEPC010 | Upgrade of the ESRF Accelerator Complex | 2004 |
|
||
|
The ESRF, the first third generation synchrotron radiation source, opened its first beamline in 1994 and has been continuously developed since then to satisfy the user community. However, the need arose to make a major upgrade of the infrastructure and accelerator complex in order to fulfil the request for new scientific applications*. The experimental Hall will be expanded and half of the beamlines reconstructed. The storage ring lattice will be modified to provide space for longer as well as a larger number of insertion devices. New insertion devices will be developed possibly based on in-vacuum permanent magnets at cryogenic temperature. The electron beam positioning system will be rebuilt to provide a higher photon beam stability. The RF system will face a major reconstruction with a new type of RF transmitters and HOM damped cavities allowing stable operation at a ring current of 300 mA without feedback. The injector system will be upgraded to operate the 16 and 4 bunch fillings in the top-up mode in order to increase the average current and obtain a higher photon beam stability.

| WEPC022 | Operation and Recent Developments at the ESRF | 2028 |
|
||
| The ESRF has been operating for a period close to fifteen years and is now looking towards an ambitious upgrade programme for the coming ten years. This paper reports on the performances achieved today with the ESRF storage ring, as well as developments accomplished and projects underway. These include a new filling mode for pump and probe experiments, the evolution of insertion devices, developments to improve beam stability, in particular transverse and longitudinal multibunch feedbacks, and the current increase from 200 to 300 mA. The upgrade of the lattice to accommodate longer straight sections and the new High Quality Power Supply system will also be presented. The machine reliability and the most important failures will be discussed. Finally, the use of an electronic logbook in routine operation will be presented, and the status on the control system including TANGO collaboration given. |
