| TUPP003 | A Common Diagnostic Platform for Elettra 2.0 and FERMI | 280 |
|
||
| Elettra 2.0 is the project of upgrading the current synchrotron light source to a low emittance machine. In this framework, various components of diagnostics have to be refurbished due to the obsolescence of the same or due to the tight requirements of the new accelerator. In this paper we present a high performance FPGA-based (Altera/Intel Arria 10) digital board developed internally, capable of hosting two FMC modules, equipped with DDR3 ram and 10 Gb/s Ethernet links. The presence of the FMC connectors allows a flexible use of the board: various configurations of A/D and D/A converters (different number of channels, resolution, sampling rate) can be obtained, also with various I/O ports for trigger and synchronisation. These features make it applicable as a base platform for various applications not only for Elettra (electron and photon BPMs, DLLRF systems, etc.) but also for Fermi (cavity BPMs, bunch arrival monitor, link stabiliser). The peripherals on board have been fully debugged, and probably a new version with a SoC (System on Chip) will be released in the next future. | ||

Beam Measurements Results of a BPM System Implementing the Pilot-Tone Stabilization Concept | |
|
||
| The next generation light sources will require Beam Position Monitoring systems capable of performing high resolution measurements as well as assuring long-term measurement stability. One possible solution to stabilize the position measurements long-term drifts is using a pilot-tone signal which is transferred together with the BPM signal and measured by the BPM electronics. To investigate this solution, Elettra Sincrotrone Trieste developed a pilot-tone injector which was used together with the commercial BPM readout electronics Libera Spark to validate the concept with several measurements related to the typical figures of merit of the BPM systems: position resolution, long-term drift and dependence from beam current and fill pattern. In addition, the behavior of the system was studied under different environmental conditions (changes in temperature and humidity). After the first measurements with beam at Elettra Sincrotrone Trieste, the test-setup was provided also to other laboratories and the measurement results are presented in this paper. | ||
