D -- GAMMA-RAY INSPECTION SYSTEM DUE 031699 POC Sandy Broten, Contract Specialist, 520 533-8944 (i)This is a Sources Sought for commercial items. (ii) GENERAL INFORMATION: There is a requirement for the USCS to procure Non-Intrusive Inspection (NII) systems similar to the Vehicle and Cargo Inspection System II (VACIS II) which is a gamma ray system. The gamma-ray inspection system shall be capable of inspecting the largest commercial vehicles that are allowed on the public roadways. The range of suspect vehicles to be inspected will include steel-walled tankers, large semi trucks, towed vehicles, cargo containers, automobiles, pick-up trucks and trailers. Such examinations are aimed at detecting items such as illicit drugs and other contraband prohibited from entry into or exported from the United States. The gamma-ray inspection system will be used as an inspection tool that can be re-located to a variety of U.S. Ports of Entry. The system desired shall be modular in design and capable of being disassembled, relocated and reassembled. The system shall be operated outdoors during a 24-hour day, and in a variety of climatic environments such as the hot arid desert, warm and humid coastlines and extreme cold northern borders of the United States. The gamma-ray inspection system shall be capable of a minimum of 16 consecutive operating hours daily. The gamma-ray inspection system shall consist of the following five major subsystems: (1) Detector and Source Transport Systems; (2) Gamma-Ray Detectors and Detector Tower; (3) Gamma-Ray Source (one Curie Cesium-137) and Housing; (4) Signal Processing/Operator's Console and Display Subsystem; and (5) Mobile Command Center Subsystem. Suspect vehicles to be inspected will be parked in the space between the detector and source transport system that travel in a synchronized motion parallel to each other. The system shall be capable of scanning suspect vehicles up to maximum dimensions of 8' 6" wide x 14' 6" high x 65' long in one scan. The detector electronics shall process the data and transmit it to the display system where a real-time image shall be produced. Requirements for this system represent a level of "minimum performance". The equipment shall be designed to operate with outside ambient air temperature ranging from 0 to 120 degrees Fahrenheit and humidity extremes from 10 to 100 percent. The system shall have provisions for sealing critical components from dust and dirt, such as occurs during dust storms in arid locations. The system shall be capable of being operated by a two-person team. The gamma-ray inspection system specific hardware design requirements shall include a one-curie Cesium-137 sealed source, a beam angle adjustable from 0 (direct) to 10 degrees (oblique) (motorized operation) with angle indicator, a beam width not more than 36" at 35 feet from the source and three adjustable vertical positions for the source housing of 18", 36", and 54". The system shall have a minimum scan speed of 0.7 ft/sec, the ability to resolve 0.5" objects in horizontal and vertical dimensions in the center of the inspection zone 7 feet above the ground and the ability to detect a lead brick through 2" of steel. The contrast gray scale shall have a minimum of 16 shades of gray. Requirements associated with image quality (resolution, contrast and penetration, etc.) shall be satisfied using high efficiency detectors and appropriate image processing technology. The system shall be a people, produce, and film safe in accordance with applicable federal (OSHA, EPA, NRC, FAA and FDA) and state radiological health requirements price. (iii) Current catalogs, pamphlets or a certified statement to the effect that you can provide these items as a commercial off-the-shelf procurement will be accepted. Submit to Dept. of the Army, Directorate of Contracting, Attention: Sandy Broten, Building 21112, Hines Road, Ft. Huachuca, AZ 85613 by 4:00 p.m. (Mountain Standard Time), March 19, 1999. FAX: 520.533.1600 or emailed to: brotens@huachuca-emh1.army.mil. This is NOT a request for proposal, but for planning purposes only and is not to be construed as a commitment by the Government.
