Systems Engineering Plan

4Director's Review ‐‐ System Engineering 2016 February 2

A systematic approach for designing and managing complex systems, such as the CMS detector, to ensure that they perform as an integrated whole that meets its objectives.

Sub-detectors of CMS are complex systems in their own right, requiring a systems engineering approach

The US CMS HL-LHC Upgrade Project systems engineering approach takes into account that It is part of a the international CMS Upgrade Project The international CMS Upgrade Project must integrate into an

existing operational experiment

5

Systems Engineering Approach

Director's Review ‐‐ System Engineering 2016 February 2

Coherence of the overall CMS Upgrade Project is the responsibility of the CMS Upgrade Coordinator

Overall responsibility for integration of all parts of CMS resides with the CMS Technical Coordination Team, led by the Technical Coordinator at CERN

=> The CMS Technical Coordination is the lead systems engineering organization for CMS

US CMS systems engineering procedures must be compatible with those specified by CMS Technical Coordination.

Systems Engineering in the CMS Context

Director's Review ‐‐ System Engineering 2016 February 2

Requirements flow down drive Conceptual Design Science Objectives

=> Science Requirements => Detector Functional Specifications

=> Detailed Component Specifications Developed and documented in the CMS Technical Proposal and

Scope Document Will be further detailed in Technical Design Reports to be written

by the end of 2017

Requirements and specifications will be documented and approved using the CERN EDMS

7

Requirements

Director's Review ‐‐ System Engineering 2016 February 2

Systems engineering is a project line-management responsibility

Issues internal to a US CMS subproject are the responsibility of the relevant subproject manager

Issues internal to a CMS sub-detector are the international CMS subdetector manager US CMS L2 manager works with the international manager to

ensure compatibility of US parts with the whole system

US CMS Upgrade Project Electronics and Mechanical Engineers oversee the systems engineering process within the US Project

US Project Manager, Deputy Project Manager and Project Engineers are key contacts with CMS Upgrade and Technical Coordination

Systems Engineering Management

Director's Review ‐‐ System Engineering 2016 February 2

Systems Engineering Requirements

9Director's Review ‐‐ System Engineering 2016 February 2

System-level design for the CMS Upgrades are developed by the CMS Collaboration and documented in the Technical Proposal

Upgrade designs are made in the context of a system-level design of CMS as it will exist when the upgrades have been implemented

System-level designs of sub-detectors are developed by the international teams for each system. The US Project is part of these teams.

Feasibility studies are performed to demonstrate that the conceptual designs meet the functional and science requirements.

10

System-Level Designs

Director's Review ‐‐ System Engineering 2016 February 2

CMS conducts system reviews jointly under the purview of the Upgrade and Technical Coordination, involving also Electronics and Physics Coordination.

Reviews ensure that individual systems meet the requirements, are technically sound, and will function correctly within the integrated CMS experiment.

The review sequence includes: Conceptual Design Reviews Engineering Design Reviews Procurement Readiness Reviews Manufacturing Progress Reviews Installation Engineering Design Reviews

11

Reviews by CMS

Director's Review ‐‐ System Engineering 2016 February 2

US CMS HL-LHC Upgrade Project has responsibility for components and subsystems of sub-detector upgrades.

In some cases, e.g. FPIX, the US has major responsibility for a whole system.

System-level designs for US-provided components and subsystems are the responsibility of the US Project They are developed to meet the requirements and specifications

of the larger systems of which they are part. Development is done with full cooperation with the overall CMS

Upgrade Project. They are subject to the same reviews discussed above, either

individually or as part of a larger sub-detector review.

US CMS Upgrade Project Responsibilities

Director's Review ‐‐ System Engineering 2016 February 2

Interface Management

13Director's Review ‐‐ System Engineering 2016 February 2

Interface Control Documents (ICD) define interfaces between work done by different groups. Between different US groups within a single subproject Between the US-provided equipment and the rest of a sub-

detector provided by the international collaboration Between a complete sub-detector and the rest of CMS

ICDs cover all interface types Mechanical / Thermal Electrical / Electronics Firmware / Software

ICDs are controlled documents in the CERN EDMS Approval at the appropriate management level common to the

two sides of the interface.

14

Interface Control

Director's Review ‐‐ System Engineering 2016 February 2

Interfaces between a sub-detector and the rest of CMS are the responsibility of the CMS Technical Coordination, specifically the CMS Integration Coordinator They are generally handled by the relevant CMS sub-detector

manager. The US Project will participate to the extent that they are

responsible for equipment involved in the interface.

Definition and control of interfaces is an important component of the CMS technical reviews

15

Interface Control

Director's Review ‐‐ System Engineering 2016 February 2

QA / QC

16Director's Review ‐‐ System Engineering 2016 February 2

QA / QC is guided by the Fermilab Quality Assurance Policy and Integrated Quality Assurance plan. QA/QC systems specific to this Project will be developed and

documented in a Quality Management Program Plan to be submitted before the NSF PDR and DOE CD-1

The QA/QC elements will draw heavily on experience from similar projects, including the on-going Phase 1 US CMS Detector Upgrade Project

Prompt identification and documentation of deficiencies and understanding of root causes are key aspects

Project personnel are expected to identify non-conformities as well as potential areas for improvement

17

QA / QC

Director's Review ‐‐ System Engineering 2016 February 2

Key elements of the QA/QC Plan include: Systems to assure that only properly trained and qualified

personnel are involved in design, manufacture and installation of detector components

System to qualify vendors as part of the bid process Documentation of specifications, acceptance criteria and

operating parameters of all items provided by collaborating institutions or commercial vendors

Sample testing of components and 100% testing of major subassemblies

Control of non-conforming items to ensure that they are not used

18

QA / QC Plan Elements

Director's Review ‐‐ System Engineering 2016 February 2

Traveler System for work done in US CMS production facilities: Documents key production steps and measurements taken to

verify them Identify, report, correct and trend non-conformance situations Provides data that may be useful in installation and

commissioning of components and subsystems Ensures that problems are identified at the earliest possible

opportunity to allow immediate remedial action to be taken.
