Libera Book 2021
The accelerator community knows us as the Libera folks. It looks like we’ve left an impression since our story began back in 2003. Since then, nine out of ten synchrotron light sources around the world have been equipped with our Libera beam position stabilization systems. But Libera is much more than just the sum of its products. It means the best possible performance for the price. It means innovation, quality, and reliability. It means long-term support. It is the relationships we have nurtured over the years with our customers that we cherish most. Libera products seamlessly combine hardware and software into powerful instruments that measure a variety of beam parameters. Those measurements are then used in feedback loops to optimize the performance of a particle accelerator. Different accelerators have different needs. However, through the reconfigurability and modularity of Libera instruments, we can accommodate a variety of end-user requirements. Libera instruments are developed and manufactured by the Instrumentation Technologies Company. Established in 1998, the business has grown from a garage-based start-up to an established company known for its Libera and Red Pitaya products, and for launching the Center of Excellence for Biosensors, Instrumentation and Process Control (COBIK).
Web GUI Development and Integration in Libera Instrumentation – ICALEPCS 2021
During the past 5 years, Instrumentation Technologies expanded and added to the embedded OS running on Libera instruments (beam position instrumentation, LLRF) a lot of data access interfaces to allow faster access to the signals retrieved by the instrument. Some of the access interfaces are strictly related to the user environment Machine control system (Epics/Tango), and others are related to the user software preferences (Matlab/Python). In the last years, the requirement for easier data streaming was raised to allow easier data access using PC and mobile phones through a web browser. This paper aims to present the development of the web backend server and the realization of a web frontend capable to process the data retrieved by the instrument. A use-case will be presented, the realization of the Libera Current Meter Web GUI as a first development example of a Web GUI interface for a Libera instrument and the starting point for the Web GUI pipeline integration on other instruments. The HTTP access interface will become in the next years a standard in data access for Libera instrumentation for quick testing/diagnostics and will allow the final user to customize it autonomously.
New RF BPM Electronics for the 560 Beam Position Monitors of the APS-U Storage Ring – IPAC 2021
With the upgrade of the APS storage ring to a multi-bend achromat lattice, 560 RF Beam Position Monitors (BPMs) will be required. The projected beam sizes are below 10 microns in both horizontal and vertical planes, putting stringent requirements on the BPM electronics resolution, long-term stability, beam current dependency and instrument reproducibility. For the APS-U project, the Libera Brilliance+ instrument has been upgraded in technology and capabilities, including the addition of independent multi-bunch turn-by turn processing and an improved algorithm to further reduce artifacts of the crossbar switch. More than 140 instruments, equipped with 4 BPM electronics modules each, are being delivered to Argonne National Laboratory, consisting of the largest scale production for Instrumentation Technologies. In this contribution, the extensive test conditions to which the instruments were exposed and their results will be presented, as well as the beambased long-term drift measurements with different fill patterns.
