	In the last years, there has been a growing interest in using the pilot-tone technique for long-term stabilization of electron beam position monitors in synchrotrons. At Elettra, after an internal development, the effectiveness of this approach was proven with tests in the laboratory and on the storage ring. The pilot-tone scheme will be adopted for the eBPMs that will equip Elettra 2.0, the low-emittance upgrade of the present machine. In order to support the development, industrialisation and production of the overall system, a partnership with Instrumentation Technologies has been signed. With the extensive experience with the Libera instruments, the company will be engaged in improving the BPM system developed by Elettra and getting it ready for serial production. This paper presents the current status of the BPM system, with an emphasis on the efforts done to improve the key performance of the system and to address its weaknesses (e.g. enhancing single bunch response and low currents sensitivity) within the industrialisation process, with the goal to get to a reliable system, easy to maintain and that meets the multiple project requirements for the new storage ring, the booster, the pre-injector and the transfer lines.

MOPP30	Tests of the New BPM Long Term Drift Stabilization Scheme Based on External Crossbar Switching at PETRA III	123

	The PETRA IV project at DESY aims to upgrade the present synchrotron radiation source PETRA III at DESY into an ultralow-emittance source which will be diffraction limited up to X-rays of about 10 keV. Using a multi bend achromat lattice, the small PETRA beam emittance translates directly into much smaller beam sizes at the insertion device source points, thus imposing stringent requirements on machine stability. In order to measure beam positions and control orbit stability to the requisite level of accuracy, a high resolution BPM system will be installed which consists of about 700 individual monitors with the readout electronics based on MTCA.4 as technical platform. In order to fulfill the requested long-term drift requirement to be less than 1 micron over a period of seven days, due to the PETRA-specific machine geometry the BPM cable paths have to be stabilized in addition. To achieve this demand, the well proven concept of crossbar switching was extended such that the analogue switching part is separated from the read-out electronics and brought as close as possible to the BPM pickup. This contribution summarizes first proof-of-principle measurements which were performed in the lab and at PETRA III using a modified Libera Brilliance⁺ with external switching matrix. These measurements indicate that the concept of external switching works well and that the performance of this modified test setup fulfills the specifications.
