Description
The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN requires exceptional alignment accuracy of accelerator components to reach the luminosity targets and to ensure reliable beam operation. This accuracy is achieved with the help of the Full Remote Alignment System (FRAS), which employs a capacitive Wire Positioning System (WPS) to monitor the position of magnets, RF cavities, and other accelerator components relative to a stretched, conductive, reference wire. Each WPS sensor measures distance offsets with respect to this reference wire with sub-micron-level resolution. The sensors are connected via dedicated cables to specially designed WPS conditioning electronics for signal processing and data acquisition. These modules operate as application specific cards within CERN’s Distributed Input/Output Tier (DI/OT), a standardized framework designed for modular electronics operating in radiation-exposed environments.
To support the large-scale production and verification of over 400 WPS conditioning modules, an automated Production Test Suite (PTS) has been developed. The PTS streamlines firmware programming, automates test execution and ensures full traceability through integration with CERN's Enterprise Asset Management (EAM) platform and the Engineering Data Management Service (EDMS). This paper presents the design and validation of the PTS for WPS conditioner electronics, focusing on hardware–software integration and its role to enable reliable production testing for the HL-LHC.
