Description

Scope

During the HL-LHC IT String Day III in 2023 (link) a review was conducted on the lessons learned from the installation and commissioning activities. The event also covered the main upcoming activities, the planned test program, and discussed the progress in the procedures and software for the IT String Hardware Commissioning (HWC).

The HL-LHC IT String Day IV will start with a general introduction that revisits the recommendations for the previous IT String Day. It will also provide an update of the project status, along with an overview of the QA/QC processes implemented and the safety protocols enforced during installation and operation. Furthermore, the main objectives to be adressed during the event are outlined as follows:

a. Present the lessons learned during the installations, individual system tests and short circuit tests as part of the hardware commissioning phase performed since the last IT String Day.

b. Describe the main upcoming activities, including: the sequence and target period for installation, and the readiness of procedures and tooling.

c. Confirm the test program for the HL-LHC IT String Hardware Commissioning and the HL-LHC IT String Specific tests. Report on the status of the test procedures for the IT String Hardware Commissioning and the associated software.

The advisors nominated by the HL-LHC Project Leader and the TE Department Head will be asked to provide their feedback and recommendations to the Management as well as to share their comments with the HL-LHC WP16 core team.

Chair: Markus Zerlauth

        Feedback from the HL-LHC IT String Day III and scope of the HL-LHC IT String Day IV

        The presentation will introduce the scope and program of this fourth IT String Day, which will focus on the lessons learned from the validation of the infrastructure, warm powering system and the cryogenic distribution line, as well as the preparation of the next important phase of the cold powering system installation. We will also review the main recommendations and the status of follow-ups that emerged during the latest IT String Day in 2023.

        HL-LHC IT String Quality Assurance & Control (WP16/TE-MPE)

        This presentation provides a comprehensive overview of the Quality Assurance and Control processes implemented in the HL-LHC IT String. It describes the management of non-conformities related to the test stand, adhering to the policies established by the HL-LHC Project. It explains the tracking process of the validation tests conducted during installation and commissioning of the equipment. Additionally, the presentation covers the documentation and tools (including contribution documents, planning, and EVM) used to ensure effective project management. Finally, it discusses the communication strategy employed by the WP to report project advancements to a broader audience.

        HL-LHC IT String Technical Coordination & Safety (WP16/TE-MPE)

        This presentation will cover the methodology and organizational structure behind the technical coordination of the HL-LHC IT String facility. It will provide an in-depth update on the progress of on-site construction and commissioning activities. Key lessons learned from the IT String's construction and commissioning will be shared, focusing on technical challenges, schedule management, and the coordination of concurrent activities, along with relevant feedback provided to the HL-LHC project. Additionally, the safety strategy implemented during construction and commissioning will be revisited, with an overview of the safety protocols and operational procedures which are being developed and put in place.

        Controls and software status for the HL-LHC IT String (WP16/TE-MPE)

        The HL-LHC IT String facility includes accelerator systems such as power converters, quench protection, cryogenics, insulation vacuum and alignment. The applications for the system controls and for the operation of the HL-LHC IT String facility compose a three-layer architecture. The front-end layer is composed of Programmable Logic Controllers (PLC) or Front-End Computers (FEC). The systems’ layer is composed of monitoring, control, and supervisory applications. The operation layer is composed of supervisory, sequencer, and magnet circuit test analysis applications. As a preparation of the HL-LHC commissioning phase, the definition of all the required software interfaces, in line with the HL-LHC era, is essential to guarantee the suitable operation of the String facility control system. The readiness status of the controls and software is reported. The Dry Run tests are essential to validate the operation applications and the complete control system before the cooling and the powering test phase of the HL-LHC IT String commissioning program.
