- Description
- This publication constitutes a Broad Agency Announcement (BAA) as contemplated in Federal Acquisition Regulations (FAR) 6.102(d)(2), which provides for the competitive selection of research proposals. The contract awarded as a result of proposals submitted in response to this BAA is considered to be the result of competition to the maximum extent practicable. A formal Request for Proposals (RFP), solicitation, and/or additional information regarding this announcement will not be issued. Brookhaven Science Associates, LLC (BSA) will not issue paper copies of this announcement. BSA reserves the right to select for award all, some, or none of the proposals in response to this announcement. BSA provides no funding for direct reimbursement of proposal development costs. Technical and cost proposals (or any other material) submitted in response to this BAA will not be returned. It is the policy of BSA to treat all proposals as sensitive competitive information and to disclose their contents only for the purposes of evaluation. BSA is interested in receiving innovative proposals that offer potential for advancement and improvement in the engineering design study for the PHENIX Silicon Vertex detector (VTX). The successful offeror will be required to perform an engineering design study of components of the Silicon Vertex Detector (VTX) for the PHENIX experiment at Brookhaven National Laboratory. The VTX is a compact device, approximately cylindrical in shape with an outer radius of 20 cm and a length of 80 cm. The VTX has three main components, a central barrel containing four layers of silicon sensors (both silicon strips and pixels) with approximately 4.3 million sensor channels and associated electronics plus two end caps with four strip layers each and approximately 1.3 million sensor channels and associated electronics. The frames supporting the VTX sensors and electronics must be low mass and low density, composed primarily of carbon composite materials to allow a maximum 100 micron deflection under gravity of any component of the VTX mechanical system. The VTX must have an associated cooling system that is capable of removing up to 150 Watts of heat from the device. Together the mechanical and cooling system must add no more than 1.4% to the total mass of the detector. The company performing this job must have experience working with large channel count, silicon sensor detector systems for particle physics and space-based experiments. They must have a demonstrated track-record of design of mechanical support, cooling and alignment systems with micron-level precision and multi-project experience designing and prototyping carbon composite-based low mass mechanical support systems. The company must also have significant experience working on advanced technology mechanical engineering projects for the US Department of Energy and NASA. Tasks to be performed: 1) Barrel Ladder Staves R&D: Perform FEA modal analysis to determine the dynamic stiffness of the lay-up. Perform FEA for mass-loaded static stiffness to insure less than 100 microns of gravitational sag. Optimize for mass (low Z) and structural integrity. An analysis will be performed to determine if mounting the staves only at the end of the VTX is acceptable. Design: Design the staves to be similar in concept to those used by silicon vertex detectors of the equivalent complexity in recent particle physics or spaced-based experiments. Design the connection between the ladders and the barrel mounts. 2) Ladder Coolant Tubes plus Terminations R&D: A thermal analysis will be performed to size the ladder coolant tubes and to determine suitable connectors. Design: Design the routing of the coolant lines inside the VTX detector. 3)Barrel Mounts R&D: Perform FEA modal analyses to determine dynamic stiffness. Perform FEA for mass-loaded static stiffness to insure less than100 micron of gravity sag. Optimize for mass (low Z), structural integrity and access. Design: The cant angle and overlap specifications for precise positioning of the ladders will be incorporated into the design of the barrel mounts. The connection between the barrel mounts and the space frame will be designed. It will be determined how to precisely position the barrels through an adjustment feature. 4)Space Frame: R&D: The VTX space frame design should use a kinematic mounting technique with analysis similar to that used on silicon vertex detectors of the equivalent complexity in recent particle physics or spaced-based experiments. Perform FEA modal analyses to determine dynamic stiffness. Perform FEA for mass-loaded static stiffness to insure less than 100 micron gravity sag. Optimize for mass (low Z), structural integrity and access. Optimize the location and shape of mass reducing cutouts in consultation with Los Alamos National Laboratory project engineers. Design: Design a carbon-composite structure, octagonal in shape. Use stiffening sandwich structure end plates. Determine the best method for connecting the two space frame clamshell halves. The applicable NAICS code is 541710?Research and Development in the Physical, Engineering, and Life Sciences. This notice constitutes an announcement for the competitive selection of research proposals. This announcement is a continuously open announcement valid through 12 January 2006. Brookhaven Science Associates reserves the right to select for award all, some, or none of the proposals received. The awards will take the form of a contract. Multiple awards are not anticipated. Brookhaven Science Associates encourages Educational Institutions, Small Businesses (SBs), Small Disadvantaged Business Concerns (SDBs) and Historically Black Colleges and Universities (HBCUs) and Minority Institutions (MIs) to submit proposals under this announcement. All prospective offerors shall submit an initial technical and cost proposal, detailing the firm?s technical capabilities, comparable engineering design study work history, assets, and availability. Capability statements must demonstrate qualified available personnel with the pertinent experience, adequate organizational and administrative structure, and demonstration of the resources necessary to perform the work. Capability Statements submitted that do not provide sufficient information will not be considered. The cost proposal must include cost estimates for all tasks to be performed under the resultant contract. Prospective and qualified offerors are encouraged to submit technical and cost proposals before Jan 12, 2006. It is anticipated that one cost reimbursement contract award will be made as soon as possible after review of all technical and cost proposals. The selection of proposals for award will be based on a scientific review of proposals submitted in response this announcement. The major purpose of the evaluation will be to determine the relative merit of the technical approach of each proposal. Business and contractual aspects, including proposed cost and cost realism, will also be considered as part of the evaluation. Selection of proposals for award will be based on the potential benefits to the Brookhaven National Laboratory weighed against the cost of the proposals, in view of the availability of funds.
