a template to indicate the intended content and scope The content will be developed mostly by pulling together scattered documentation from initial LIGO However there is an intent to impose some new requirements and standards where the initial LIGO requirements required improvement 1 1 Purpose This document defines the generic requirements and standards for all subsystem designs for the Advanced LIGO AL detector The AL detector is currently defined as a single major upgrade to the initial LIGO Detector These requirements apply even for more modest upgrades to the initial LIGO Detector 1 2 Scope This document defines or refers to the requirements and standards that transcend any particular subsystem and are thus generic More detailed requirements or standards are referenced where applicable The scope includes all aspects mechanical electrical optical etc and all phases design analysis test fabrication assembly installation of the Detector 1 3 Definitions Numerous TBD 1 4

Advanced LIGO LIGO T00xxxx xx D 2 Review Requirements 2 1 Design and Test Reviews The required design reviews are defined in the Guidelines for Detector Construction Activities as follows Design Requirements Review DRR Preliminary Design Review PDR Final Design Review FDR Prototype Test Review if applicable First Article Test Review if applicable Pre shipment Review This document defines the nature and requirements of each review as well as the manner in which they are conducted These reviews are applicable to each subsystem and to the overall Detector system In additio n to these standard reviews the Detector management may require special design reviews if they deem it appropriate 2 2 Approval Release Process While most technical documentation is uncontrolled and unreleased which does not mean it is not valuable the documentation associated with contracting and fabrication is controlled so that the effect of changes on cost schedule interfaces etc can be ascertained This documentation applies to all engineering specifications drawings procedures development plans test plans interface control documents etc Generally in the LIGO document numbering scheme it is
