The ATLAS experiment will be upgraded during the next LHC Long Shutdown (LS2). The flagship upgrade is the New Small Wheel (NSW) [1], which consists of 2 disks of Muon Gas detectors. The detector technologies used are Micromegas (MM) and sTGC, providing a total of 16 layers of tracking and trigger....

description The ATLAS experiment will be upgraded during the next LHC Long Shutdown (LS2). The flagship upgrade is the New Small Wheel (NSW) [1], which consists of 2 disks of Muon Gas detectors. The detector technologies used are Micromegas (MM) and sTGC, providing a total of 16 layers of tracking and trigger. The Slow Control Adapter (SCA) is part of the Gigabit Transceiver (GBT) - “Radiation Hard Optical Link Project” family of chips designed at CERN, EP-ESE department [2,3], which will be used at the NSW upgrade. The SCA offers several interfaces to read analogue and digital inputs, and configure front-end Readout ASICs, FPGAs, or other chips. The design of the NSW Detector Control System (DCS) takes advantage of this functionality, as described in this paper.

The design of the NSW Detector Control System (DCS) takes advantage of this functionality, as described in this paper.The foreseen upgrades of the LHC accelerator and the experiments will drastically increase the data and trigger rates. To cope with the vast and low latency data flow, the ATLAS small wheel muon detector will be replaced with a New Small Wheel. Among the upgrades needed, is a radiation tolerant Slow Control Adapter (GBT-SCA) ASIC dedicated for the on-detector control and monitoring. The ASIC employs various interfaces, making it flexible to match the needs of the different operations. On the backend, the Front-End Link eXchange system will be the interface between the data handling system and the detector front-end and trigger electronics. A dedicated slow control data component was developed as the middleware from FELIX to the end users. It is based on the OPC Unified Architecture protocol and it is comprised of an OPC-UA server, that will handle the slow control traffic from the control room to the GBT-SCA and vice versa. Ultimately, various scope-oriented OPC-UA clients, connected to the OPC-UA server, will be employed to configure and calibrate the ASICs, program the FPGAs, oversee the well-functioning of the boards and monitor the environmental parameters of the detector.oai:inspirehep.net:16557792018
