Description
The purpose of this amendment is to reestablish a new closing date and to revise the specifications. 1.) The hour and date specified for receipt of offers is extended to July 7, 2006. 2.) The specifications previously provided are deleted in their entirety and replaced with the following: Specifications for a Table-top X-ray Microtomography Unit (Revised 6/22/06) The x-ray computed microtomography unit, hereafter called the XCMT unit, must be able to scan an object and output a computer file, in a standard format, which contains three dimensional absorption contrast information concerning the object's internal microstructure. The following minimum requirements are necessary. 1.) Materials: Scannable objects may be made from metals, plastics, ceramics, glasses, organic materials, geologic materials, or combinations thereof. 2.) Maximum Scannable Object Size: must be 38 mm or greater. 3.) X-ray Source: air-cooled, sealed micro-focus x-ray tube, 100kiloVolts (kV) Acceleration voltage, > 10,000 hours lifetime. 4.) X-ray Spot Size: < 5 microns at 4W, 20-100kV, 0-250 micro-Amps. 5.) Object Magnification: XCMT will be equipped with adjustable source to camera distance which provides selectable magnifications 6.) X-ray Detector: minimum 1024X1024 lens coupled camera. 7.) X-ray Filtering: capability of having up to three or more interchangeable x-ray filters for beam-hardening compensation and multi-energy scanning. 8.) Effective Pixel Size at Max. Magnification: minimum 1.6 microns or smaller. 9.) Low Contract Resolution: minimum 5 microns. 10.) Computer: minimum dual processor workstation with hard drive storage, DVD writer, monitor, mouse, keyboard, capable of image capture, with all required software necessary for volume reconstruction and volume rendering. 11.) Reconstruction Algorithms: Both back-projection for fan-beam, and cone-beam algorithms must be provided. Correction for beam hardening must be available. Network volume reconstruction must be available. 12.) Radiation Safety: <1 micro Sievert/hour or better at any point on the instrument surface. 13.) Electrical Utilities: 100-130 V AC, 4 A. 14.) Mechanical Testing: Unit must contain compression, tension and torsion stages for testing samples in situ. 15.) Software interface and controller for controlling mechanical test apparatu.
