The idea of this topic is to make the most exhaustive list of the BPMs system in all institutes.
Please indicate what your BPM system is as a reply in this topic, and I will include it in the list.
Later, we could do the same kind of list for other systems (emittance monitors, bunch-by-bunch feedback, XBPM, ...), but for the moment let's start with the most wildly used system in storage rings.
ALBA |
BPM system: | 120 BPMs (Libera Brilliance) in the storage ring
44 BPMs in the booster, 24 of them are equipped with a Libera Brilliance.
A few Libra Spark Single Pass for the Linac and transfer lines

Comments: |
88 Libera Brilliance among the 120 used for fast orbit feedback to have squared matrix, since we have 88 correctors.
Libera Brilliance are doing quite well after ~ 10 years operation but this year (2021) fans started to fail consistently and we decided to perform a full replacement campaign.
Testing 2 Libera Brilliance+ and Libera Spark+Pilot-tone in some special BPMs.
One BPM (the first after injection) is equipped with a Libera Spark Single pass and we use it for Linac to Booster injection efficiency measurements.

Diamond Light Source |
BPM system: | 172 BPMs on storage ring (168 orginally); Libera Brilliance + Libera Electron |

Comments: | For D-II, number of BPMs on storage ring increases to 252 and we intend to use pilot tone with analog front end in-tunnel and digital signal processing using mTCA platform in the Control and Instrumentation Areas [Diamond-II CDR (https://www.diamond.ac.uk/dam/jcr:ec67b7e1-fb91-4a65-b1ce-f646490b564d/Diamond-II%20Conceptual%20Design%20Report.pdf)].

ESRF |
BPM system: | 192 Libera Brilliances and 128 Libera Sparks ERXR (iTech) for the Storage Ring
75 Sparks for the Booster |

Thanks Lorraine, I added your contribution to the list.
I see that you plan to upgrade the performances of your Fast Orbit Feedback quite a bit! Increasing the correction bandwidth by a factor 7 is not negligible.
It's a good time to join your team to work on this new and exciting project ;)
Hello,
At ALBA we have in total 120 BPMs (Libera Brilliance) in the storage ring and we use 88 for feedback to have squared matrix, since we have 88 correctors (WEPD23 https://www.slac.stanford.edu/econf/C140914/papers/wepd23.pdf).
They are doing quite well after ~ 10 years operation but this year fans started to fail consistently and we decided to perform a full replacement campaign.
We are also testing 2 Libera Brimmiance+ and Libera Spark+Pilot-tone in some special BPMs.
In the Booster, we have 44 BPMs, 24 of them are equipped with a Libera Brilliance but we really only use 8. One BPM (the first after injection) is equipped with a Libera Spark Single pass and we use it for Linac to Booster injection efficiency measurements.
In the Linac and in the transfer lines we iindeed use Libra Spark Single Pass (Upgrade of BPMs and SRMs for the ALBA Booster to Storage Ring transfer line, DEELS 2017 https://www.synchrotron-soleil.fr/fr/evenements/deels-diagnostics-experts-european-light-sources).
Thank you Laura for the details of ALBA BPM system, it is now added to the beginning of this topic.
