Abstract
The Phase-2 Upgrade [1] of the CMS Outer Tracker [2] requires the production of 7608 Strip-Strip (2S) and 5592 Pixel-Strip (PS) modules, altogether incorporating 45 192 hybrid circuits of 15 design variants. The module design makes the potential repairs impractical; therefore, performing production-scale testing of the hybrids is essential. Accordingly, a scalable, crate-based test system was designed and manufactured, allowing for parallel, high-throughput testing. To reproduce the operating conditions, the system was integrated within a climate chamber, which required the development of a remote control interface and the calibration of thermal cycles. The results and lessons learned from the test system integration and commissioning will be presented.
