that CERN provides oversight to each Collaboration through CERN staff members in key management positions in each Collaboration, and through hosting of, and chairing, the Resources Review Boards, composed of officials responsible to their governments for the funding of the ATLAS and CMS Collaborations; HAVE AGREED AS FOLLOWS: Article I Purpose of the Experiments Protocol This Protocol defines the framework under which DOE and NSF, the U.S. funding agencies, and their contractors and grantees, collectively the U.S. participants, will participate in the detector Collaborations. Article II Participation by U.S. Groups of Scientists in the ATLAS and CMS Detector Collaborations Each Collaboration will have a process, defined by a Memorandum of Understanding, for admitting participating institutions which will apply equally to both CERN Member States and non-Member States. Contractors and grantees of DOE and NSF representing universities and DOE laboratories will be entitled to participate in the ATLAS and CMS detector Collaborations as provided under Memoranda of Understanding. Article III Organization of U.S. LHC Detector Collaborations The U.S. participants in the LHC Collaborations shall operate in the framework of the overall Collaborations of which they are an integral part. Each U.S. LHC detector Collaboration shall have a spokesperson and its own Project Management Plan which will describe the U.S. organization and distribution of management responsibilities. These spokespersons will represent the U.S. Collaborations before the U.S. Party, and be responsible to the ATLAS and CMS Collaborations for U.S. technical and budget-planning activities. Article IV Resources Review Boards The Resources Review Boards for the ATLAS and CMS detectors, composed of representatives of each participating funding agency and chaired by the CERN Director of Research, shall monitor and oversee resource-related matters. The U.S. Party shall be a full member of these Resources Review Boards. 5.1 5.2 5.3 Article V Memoranda of Understanding (MOUs) For the period of 1996-1997, each Collaboration has concluded an Interim Memorandum of Understanding (IMOU) that assigns responsibilities to all participating institutions, including those from the United States, for research and development (R&D), engineering design, and prototyping during the 1996-1997 period. The final responsibilities for the construction of the ATLAS and CMS detectors will be specified in Memoranda of Understanding, one per experiment, with the concurrence of the Resources Review Boards. Subsystem Technical Design Reports on the scientific and technical aspects of the detectors will be submitted by the Collaborations to CERN for approval and will be the bases for the commitments listed in the MOU. Each MOU shall cover the actual construction of its detector and its installation in the underground experimental area, and shall include the distribution of tasks and other responsibilities for all participating institutions, including those from the United States, as well as the organizational, managerial, and financial guidelines to be followed by each Collaboration. 6.1 6.2 Article VI Responsibilities of U.S. Participants in the ATLAS and CMS Collaborations The U.S. participants will have responsibilities for R&D, engineering design, prototyping, fabrication, and normal maintenance and operation of detector systems and components as agreed to and described in the IMOUS, and the MOUS and their addenda. The U.S. participants will provide specified equipment to be built by or under the supervision of U.S. institutions. They will also contribute, in whole or in 6.3 part, items of a largely industrial nature considered as part of common projects which are the responsibility of the overall Collaboration ("Common Projects"). Such items will be funded directly or indirectly by all participants in the Collaborations, in accordance with the provisions of the IMOUS and MOUS, and will be subject to the approval of the Resources Review Boards. Requirements for cash or cash-equivalent contributions from U.S. participants in the ATLAS and CMS Collaborations, including contributions to Common Projects, will be specified in the IMOUS and MOUS. Responsibility for such contributions will be in conformance with Article VII below, and will be limited to the amounts stated in the IMOUS and MOUs, except by mutual agreement among CERN, the Collaborations, and the U.S. Party. 7.1 7.2 7.3 7.4 Article VII Funding of the U.S. Participation in ATLAS and CMS To enable the U.S. participants to meet their responsibilities during the detector research, development and construction phases, DOE will provide total funding budgeted at and not to exceed $250,000,000 (which includes contingency) to the U.S. ATLAS and CMS Collaborations, and NSF will provide funding not to exceed the National Science Board authorized amount of $81,000,000 (which includes contingency) to the combined U.S. ATLAS and CMS Collaborations. The sum of DOE and NSF funding is to be split approximately equally between the two detectors. This funding will be subject to the availability of appropriated funds. DOE and NSF will each be responsible for its own funding commitment. The application of these funds to pay for detector system costs will follow standard DOE and NSF accounting practices. Detector system cost estimates presented to and reviewed by CERN utilize CERN accounting policies and practices. The U.S. Party will assume no responsibility with respect to the validity of such cost estimates. These funds shall only be used for those U.S. responsibilities identified in 8.1 8.2 8.3 8.4 8.5 Article VIII Responsibilities of CERN The general obligations of CERN as host laboratory, and of the participating institutions are laid down in the document "General Conditions for Experiments Performed at CERN“ (April 1989), which is considered a part of this Protocol. The Financial Guidelines for LHC Collaborations (CERN/FC/3796, dated August 30, 1995) is also considered a part of this Protocol. It is understood that the design, fabrication, and operation of the detectors will be managed by the ATLAS and CMS Collaborations, respectively, with CERN having oversight responsibility and providing continuous monitoring through CERN's Research Board and its LHC Committee. The Research Board is responsible for CERN's entire experimental research program and is chaired by the Director General, whereas the LHC Committee reviews for the Research Board the technical progress of the LHC experiments. The Technical Co-ordinators of the ATLAS and CMS Collaborations shall be CERN staff members, and shall have overall responsibility for technical aspects of detector construction. Their responsibilities shall include integration of the subdetectors, safety, infrastructure at CERN, surface and experimental areas, services, installation, machine interface, and test beams. Similarly, the Resource Co-ordinators of the ATLAS and CMS Collaborations shall be CERN staff members and shall have the responsibility for monitoring the financial aspects of the detector projects, including budget and manpower planning and the MOUS, as well as the responsibility for the financial aspects of the Common Projects and associated Common Funds. CERN shall have the responsibility to approve the appointments of the Technical and Resource Co-ordinators, and to ensure that they have the staff and engineering support required to carry out their responsibilities. It will be CERN's overall responsibility to ensure, as best as it can, that there is a satisfactory match between the available resources (including funding and manpower) and the approved detector projects. CERN, through the Resource and Technical Co-ordinators, will have oversight responsibility for Common Projects and Common Funds. Article IX CERN Support for U.S. Scientists CERN will provide U.S. scientists participating in the LHC program the same level of facility support that it normally provides to all its visiting scientists. Article X Potential Detector Upgrades Should the ATLAS and/or CMS Collaborations seek to improve and upgrade their detectors some time in the future, such upgrades will be the subjects of new MOUS, or addenda to existing MOUS, to be negotiated within the Collaborations. The access of U.S. contractors and grantees to participation in the Collaborations will be extended to participation in the upgraded detectors on the same basis as described in Article II of this Protocol. Article XI This Protocol shall enter into force upon signature, and remain in force for twenty (20) years from the date of signature, followed by automatic renewal on a year-byyear basis, provided the International Co-operation Agreement remains in force. Article XII Amendment Procedure The Parties may amend this Protocol by written consent. Article XIII Final Provisions This Experiments Protocol shall form an integral part of the International Cooperation Agreement. |
