Description
Cryogenics systems are critical within the framework of the LHC accelerator and its detectors. Interruption of refrigeration capacity has direct impact on accelerator availability and the acquisition of physics data.
During the second Long Shut down 2, spanning from 2019 to 2020, one key element for reliability enhancement was the application of a robust preventive maintenance and calibration policy.
Lessons learned after the first previous Long Shut down has allowed to develop, optimize, and implement the tools and methods, in particular concerning the criticality analysis and the methodology for calibration of high precision instruments.
In an effort to improve the quality and the traceability for the maintenance instrumentation teams, a new integrated calibration tool application has been developed and implemented with a software bridge to communicate with the existing CMMS Database.
This implementation of the new calibration tool and associated database, as well as feedback for several months preventive maintenance, will be explained in the poster.
