The Tune & Orbit Feedback system has been heavily renovated during LS2 based on the experience gained over the Run2 of the LHC. In the first part of this presentation, the hardware, software and operational changes will be presented.
Given that Tune & Orbit Feedback is one of the key systems of the LHC, extensive testing has been performed to validate the new software requirements. These tests follow industry-standard best practices including black-box testing, continuous integration and acceptance tests in a closed-loop simulated environment. Testing methodology, experience and results will be explained.
The renovated system has been validated during the 2021 LHC Beam Test and the results, along with the impact on the Run3 LHC operation, will be presented.
