Description

Two (2) portable multi-channel analyzer gamma spectroscopy and neutron detection systems are needed. Both systems shall be equipped with the same components that meet the minimal acceptance specifications. Inclusion of product literature alone without stating that equipment meets all specifications listed or unless a clear exception is included stating that the unit does not meet a certain specification is not acceptable. Quotes shall include pricing for shipping to Montgomery, Alabama. The systems shall be of a single unit design, battery operated (rechargeable), and contain all hardware and software components to function with stand alone capabilities for spectral collection, isotopic identification, and storing of at least 200 individual spectra in memory. The one piece unit shall contain at a minimum a 1.5 by 2 inch sodium iodine (NaI) detector internal to the unit. A moderated helium (He3) neutron detector shall also be included in the one piece unit. The ability to connect an external NaI detector shall also be provided. The quote shall also provide cost for a more sensitive 3 by 3 inch external NaI detector will all cabling and documentation required to make the change and to recalibrate the unit and/or change calibration parameters from a previous calibration. Both portable systems shall include: 1) A 512 or 1024 channel spectral memory for the NaI detector, at a minimum. The spectral range must be capable of covering 0 to 3000 kiloelectron volt (keV). 2) The count rate/exposure rate of the neutron detector must be indicated to the operator on a separate but simultaneous basis along with the gamma exposure rate data. 3) The usable energy range of the detector must include 25 to 3000 keV. 4) The unit must have an automatic set up feature allowing the hardware (including high voltage adjustment and amplifier gain) to set itself so the instrument operator has only to place check sources on detector when prompted to do so. 5) The unit must provide for automatic site specific background accumulation as part of the auto set up. 6) A fully manual mode of operation must be provided through menus to allow for traditional multi-channel operation (start, stop, clear, preset accumulation live time, etc). 7) The unit must measure the ambient dose rate in low dose fields and allocate the dose rate among isotopes based on the energies found in the spectra. 8) The unit shall provide library based isotopic identification using an editable library using a stand alone system. A base library shall be provided that can be edited. 9) The ability to set alarm thresholds for selectable isotopes by the operator shall be provided. If an alarm condition is met, the unit shall automatically store the spectrum that resulted in the alarm condition. The stand alone unit must be capable of storing at least 200 spectra. 10) A separate Microsoft Windows 95/98/2000/NT compatible software program must be provided to retrieve stored spectra and provide for additional spectral analysis including the ability to use the stand alone unit as a traditional megacurie analysis (McA) and perform energy and efficiency calibrations and analyses. The stand alone unit must interface with a laptop computer for data transfer without the need for special personal computer (PC) cards. 11) The unit shall have the capacity to interface directly with a printer to generate analysis results and spectra in the field without connecting to a PC or laptop. 12) A 110 volt alternating current (VAC) 60 hertz (Hz) battery charger shall be provided for charging. 13) A 12 volt direct current (VDC) battery charger capable of connecting to a 15 amp vehicle power port shall also be provided. 14) Include as a separate line item a quote for a printer to be used with the unit. 15) The unit shall come with a lockable ruggedized case suitable for airline transport. Warranty Requirements: Minimum 90 day warranty for parts and labor. Date of Delivery: System must be shipped and ready for use by 15 July 2001. Place of Delivery: National Air & Radiation Environmental Laboratory, 540 South Morris Avenue, Montgomery Alabama 36115-2601. Quotes may be submitted electronically (Word Perfect 9.0 and Lotus 1-2-3 9.5 compatible formats) to the Contracting Officer by Noon local Washington, D.C. time on Thursday, 12 July 2001 or by facsimile (202) 565-2554. Early submissions are encouraged.
