The present ATLAS innermost endcap muon station will be replaced by a New Small Wheel (NSW) detector to handle large trigger and readout data rates expected at high luminosity LHC runs. Two new detector technologies, Resistive Micromegas (MM) and small-strip Thin Gap Chambers (sTGC), will be used for triggering and tracking. A common readout path and two separate trigger paths are developed....
Abstract: We present a detailed description of the design, prototyping and production of the hybrid circuits for the front-end electronics of the Upstream Tracker at LHCb. The multilayer flexible circuits are design to host the front-end chips, ensure a low radiation length and withstand the harsh environment conditions of the data taking.
To instrument the 60 million ATLAS ITk Strips Sensor channels, CERN developed the mixed-signal ABCStar front-end readout ASIC. Over 350,000 devices on 753 wafers containing 466 ASICs each will be extensively tested to provide the chips required for sensor modules. Carleton achieved a 3-10 times improvement in throughput, without compromising test coverage or data collection, by developing new...
Up to fifty thousand front-end and service hybrids are required for the CMS Tracker Phase Two Upgrade. These hybrids, which are built on carbon fibre stiffened circuits and contain several flip-chip ASICs, will be glued in module structures, making repairs almost impossible. Due to their complexity, testing within production is a very important aspect. A multiplexed testing infrastructure,...
The Low-Power Gigabit Transceiver (lpGBT) is a radiation-tolerant ASIC designed to implement multipurpose high-speed bidirectional serial links in HEP experiments. Having more than 320 programmable registers, the ASIC is highly configurable. Its test must cover a large variety of functionalities which will be validated at three different power-supply voltages, two temperatures and over more...
