66 -- X-RAY POWDER DIFFRACTION SYSTEM Contact Michele B. Spencer, Contract Specialist (202) 927-8820, Charles H. Logan, Contracting Officer (202) 927-8820. The Bureau of Alcohol, Tobacco and Firearms intends to purchase an X-Ray Powder Diffraction System to identify explosives in bulk form and to analyze explosive decomposition products in post-blast residues. The diffraction system must be a completely integrated analysis system for X-ray powder diffraction combining a high precision goniometer with high resolution optics, a high efficiency 3KW generator, and accessories and services as specified, while being compatible with the existing installation. Configuration of Automated X-ray Powder Diffraction System: (1) High precision goniometer must be operable in independent Theta mode and must have programmable sample spinning for continuous rotations with revolutions up to 120 per minute and step rotations; (2) Integrated high voltage supply for X-ray tube; (3) Integrated Incident beam optics; (4) Integrated diffracted beam optics; (5) Monchromator assembly for Cu radiation; (6) Integrated Xe detector; (7) Integrated microprocessor; (8) Long fine focus Cu X-ray tube; and (9) Sample changer: 20 position magazine type sample changer, and 2 magazine for changer. Automated data station: hardware must consist of CPU and all necessary accessories; software operating system must be Microsoft Windows/DOS compatible; capable of complete multiuser functions; basic data collection capability; must have a search/match identification capability; Profit fit and quantitative capability; and include both JCPDS PDF-1 and PDF-2 licenses and databases, on CD-ROM and hard disk as appropriate, set 1 thru current set. Accessories, installation, training, documentation and warranty: (1) system shall be supplied with Haskris water chiller - water to water recirculation; (2) system shall be supplied with 18 low background (SiO2) sample mounts and holders; (3) system shall include three powder holders, and three holders for odd shape samples; (4) system shall be supplied with a powder preparation tool; (5) installation of the system shall be provided; (6) on-site application training (at least 1 day) shall be provided; (7) instrument operation/software training (at least 4 days) for one person shall be provided at a facility designated by ATF; (8) one year warranty for new systems or new components for all systems and labor shall be provided; (9) operators manuals, software manuals and all other necessary documentation shall be provided with the system; (10) shall supply a voltage regulator capable of stabilizing 240 Volt/40 Amp line, (+1-% and /or -5%) of specified mains voltage at a rate of 0.12 seconds/1%. Compatibility for new and existing systems: All supplied components must be operationally compatible, software compatible, sample holder compatible and able to share spare parts with existing Philips 1800 system. It is a goal of the ATF laboratory system that all three labs use standard methods, procedures, and techniques in the examination of explosives and bombing evidence, and be able to share data and procedure files. All interested parties must submit a technical proposal that includes price and demonstrates the capability to meet all requirements. The proposal must be submitted in writing within 15 calendar days from the date of this announcement. NO TELEPHONE REQUESTS. NO SOLICITATION DOCUMENTATION. FAX DOCUMENTS WILL NOT BE ACCEPTED. See Note 22. (303)
