The Standard Industrial Code is 3844, and the business size is 500 employess. This requirement is a Small Business set-aside. A. The X-Ray Diffraction System shall consist of an image plate detector including controller, theta stage, x-ray mirror, 6-piece set of erasing lamps, x-ray shutter, re-installation and four foot extension to existing radiation enclosure, data processing software, and computer controlled crynogenic system. B. The system shall allow users to select pixel sizes of 50 microns x 50 microns, 100 microns x 100 microns, 200 microns x 200 microns. C. The system detector shall consist of a dual photo multiplier configuration having a dynamic range of 100,000. D. The sensitivity of the system detector shall be I photon per ADC or better. E. The system shall read plates in such a way that coordinate conversion to orthogonal coordinates is not required. F. All system mirrors shall be helium purged to limit air scatter and oxidizing effects. G. The optical portion of the system shall have remote control of mirror translation, curvature, and slit aperture. H. The diffraction system shall include a subsystem having the capability to operate at -180 degree centigrade temperatures without the use of liquid nitrogen. I. The system shall include a flexible transfer tube allowing for positioning in any orientation from vertical to horizontal. J. The Contractor shall furnish all items necessary to allow for mounting the Diffraction system to an existing Rigakku RU200 rotating anode generator. K.Shall include a HKL or equal, area detector processing software package capable of reducing collected data. Offers must be in writing and are due no later than TWENTY-ONE (21) DAYS after publication of this notice. Please cite the solicitation number on your bid. T.
