66 -- ULTRASONICS SCANNING WORKSTATION SOL N00421-96-R-5098 DUE 062496 POC Jessica Blackwell, Contract Specialist, (301)342-1828, ext. 146 JoAnn Gough, Contracting Officer, (301)342-1828, ext. 150. This is a notice of intent to Request a Proposal and negotiate on an other than full and open competitive basis for the purchase of one fully automated Ultrasonics Scanning Workstation to perform pulse echo immersion A-scans, B-scans and C-scans on a wide range of polymer matrix composites, able to image and analyze the data. This requirement will be negotiated on a sole source basis with Ultra Image International, 2 Shaw's Cove, New London, CT 06320. In accordance with FAR 6.302-1, only one responsible source and no other supplies or services will satisfy agency requirements. This is primarily due to the requirement for compatibility with the existing ultrasonic inspection systems in use - Ultra Image III and Ultra Image IV. The following is a summary of the elements or characteristics that the Ultrasonics Scanning Workstation must possess. The ultrasonics workstation must include a 3'x4'x18'' transparent immersion tank, with a water conditioning system consisting of a pump, filter, and necessary plumbing lines and fittings. The Ultrasonics Scanning Workstation shall be able to scan and index the transducer a minimum of 42 inches, with scan and index steps adjustable in the range of .005'' to .25''. The angle of incidence of the ultrasound beam shall be controlled by a manual gimble. Maximum scanning speed must exceed 8 inches per second when acquiring data in the time-of-flight and amplitude acquisition mode. Scan and index positions shall be controlled by AC servo motors. The Ultrasonics Scanning Workstation shall include a 20 Mhz, 0.75 inch focused transducer, a 10 Mhz, 1.0 inch focused transducer and a 1 Mhz, 2 inch focused transducer. The Ultrasonics Scanning Workstation shall include a 486DX266 processor with a 1GB internal hard drive for data storage and include 4 hardware gates. The system shall include an external monitor, keyboard, mouse, 1.44 MB, 3.5 inch floppy drive and at least one serial port. The system must support a printer and an external data storage drive to serve as an archive. The system must sample at rates up to 100 Mhz and shall include 0.5 Mhz to 50 Mhz signal bandpass filtering and input signal amplification. The system must include a spike pulser preamplifier which is impedance matched to the receiver. The pulser must have software selectable gain and input impedance controls and shall operate in pulse echo mode and thru transmission mode. Pulser shall have a maximum pulse amplitude of at least 300 Volts. All system operations shall be fully integrated and compatible, utilizing one software package. The system must be capable of displaying and annotating 2D and 3D colored displays from the scanned data. The system shall display live video in user sizable window, and display the A-scan signal and up to 4 amplitude/time-of-flight images in real time during acquisition. The system must be upgradeable, contain 4 independent channels, logarithmic preampifier and be expandable to 32 MB RAM. Software must be upgradeable to include frequency domain analysis, A-scan signal capture, B-scan imaging, simultaneous display and processing of A-, B-, and C-scans, image filtering, feature mapping, distance-amplitude correction, flaw measurement, back wall tracking and computerized flaw search and identification. Must be suitable to modular expansion to support a z-axis/turntable ultrasonic immersion scanning system. Contractor shall provide turn key installation, on site training and a standard commercial warranty. Government expects delivery 120 days after contract award. See Numbered Note(s): 22. (0173)
