TI - System and Subsystem Engineering of Long Baseline Detectors J2 - Proc. of MEDSI2020, Chicago, IL, USA, 24-29 July 2021 CY - Chicago, IL, USA T2 - Mechanical Engineering Design of Synchrotron Radiation Equipment and Instrumentation T3 - 11 LA - english AB - This talk will give an overview of the system and subsystem engineering and development of long baseline detectors, with a focus on neutrino experiments such as DUNE, and gravitational wave detectors such as LIGO. It will emphasize common features to the development and execution of these decade long programs, across the various phases of technology development and system integration. It will highlight key features of the development process to handle the complexity of these large systems. The presentation will cover the various phases of the system development, starting from definition of requirements and general system architecture, driven on the one hand by high level science goals and on the other hand by technology readiness. Continuing with the conceptual design phases, and the selection of most suitable technology to meet not only the science requirements, but also the project constraints on cost and schedule, and operations goals on duty-cycle, reliability and longevity. We will cover the important steps of prototyping and testing necessary to demonstrate technology readiness and to inform the final design. Following up with phases of interface definitions in between sub-systems and with conventional facilities, and related system integration steps. We will describe the final design and engineering phases with respect to the subsequent steps of installation, testing, commissioning and operations.
