This solicitation is being issued as a Request for Proposals (RFP) for an for a UHV system designed for scanning tunneling microscopy (STM) and related techniques at variable temperatures, and optimized for operation at temperatures below 20 Kelvin (K) with liquid helium (LHe) cooling. Using a high-capacity LHe bath cryostat, it shall be possible to cool the entire microscope, including the STM head, probe tip, and sample, to temperatures below 5 K. The instrument shall permit microscopy with atomic resolution on conducting surfaces, including semiconductors, ultrathin insulators, and metals. The microscope and its control electronics and software shall be capable of state-of-the-art tunneling spectroscopy functions with highest spatial and energy resolution. The microscope shall further be optimized for atom and molecule manipulation at surfaces. The instrument shall provide optical access to the sample as well as access ports for exposing the sample to gases or atomic/molecular beams. Samples and probe tips shall be exchangeable in-situ. Cooled samples shall be transferable into the microscope while maintaining a sample temperature below 20 K. The LT-STM system shall consist of three interconnected, individually pumped UHV subsystems: a main chamber holding the cryogenic STM; a preparation and analysis chamber holding a manipulator for sample heating and cooling, and equipped with an electron energy analyzer and dual anode X-ray source for photoelectron spectroscopy, one ion sputter gun for sample cleaning, one single-pocket electron beam evaporator, and with several additional ports for attaching optional instrumentation for sample preparation; and at least one load-lock chamber for fast loading of samples and probe tips into the system. In addition it shall include all necessary peripheral systems, such as a vibration damping system, controllers for all vacuum-related functions, control electronics for all STM imaging, spectroscopy, and manipulation functions, computers, control and measuring software, etc. In addition to the manufacturer?s specification for a state-of-the-art LT-STM system, the instrument shall also be designed to meet BNL?s special requirements as delineated in the specification. This, acquisition, is a, ?Best Value?, procurement. The utilization of this procedure is expected to provide the greatest overall benefit to BSA/BNL. ?Best Value? employs a trade off process that permits award to other than the lowest priced offeror or to the highest technically rated offeror. The tradeoff process, associated with Best Value involves a comparative weighing of the evaluation factors and sub-factors identified in the Request for Proposals (RFP). Specifically, the trade off process involves selecting the most advantageous offer based upon an integrated assessment of both non-cost/price factors, taken in their assigned relative importance. The following factors, in their relative order of weighting, will be utilized to evaluate the offers: - General Technical Specifications: Submit operating specifications for the proposed LT-STM system utilizing the same format (Section and Sub-Section numbering) presented by the specifications contained in the solicitation. - Upgrades and Expandability: Upgrade components or add-on sub-systems currently existing, under development, or planned for the future should be discussed. - Performance Risk: Submit references, points of contact and telephone numbers for all installations of LT-STM or similar systems for the last 3 years. Proposals are due March 23, 2006, by 4:00 PM, EDT, and shall be submitted to Brookhaven Science Associates, Brookhaven National Laboratory, Attention: D. Paveglio, Bldg. 355, Upton, NY 11973, by US mail This RFP has been sent to the following known manufacturers: SPECS GmbH Voltastr. 5 13355 Berlin Omicron - NanoTechnology GmbH Limburger Str. 75 65232 Taunusstein RHK Technology, Inc. 1050 East Maple Road Troy, MI 48083 All other interested manufacturers may down load the Request For Proposal attached to this announcement.
