AS&E develops MICRO-DOSE™ Personnel Inspection System - a precursor to BodySearch™.

1978
With funding from NASA, AS&E successfully launches the Einstein Observatory - the world's largest X-ray telescope designed by the AS&E Space Division. Einstein located more than 7,000 X-ray sources until 1981.

AS&E signs a significant agreement with Pfizer Medical Systems for the continued development of Medical MICRO-DOSE™ Systems.

1979
AS&E designs an X-ray telescope for unique NASA mission to study dynamics of the sun and interplanetary medium.

The first X-ray images are successfully recorded in tests of AS&E's 10x X-ray Microscope for the Los Alamos Scientific Laboratory.

1980
AS&E introduces MICRO-DOSE X-ray System Model 130, for carry-on luggage for airlines, as well as Model 122, an all-purpose system for baggage and parcel inspections.

1981
As AS&E's new MICRO-DOSE inspection products increase in demand, AS&E offers the new Model 50, for the inspection of small parcels and letters, as well as the Model 100 for baggage and large parcels.

1983
AS&E moves to a new building at Fort Washington in Cambridge, Massachusetts.

AS&E receives a $2 million contract from Lockheed Missile and Space Company to design a Computed Tomographic (CT) inspection system for the quality control inspection of 7-foot diameter Trident D-5 solid rocket motors.

1984
AS&E works in conjunction with the Harvard-Smithsonian Center for Astrophysics to build a high-resolution X-ray image detector for ROSAT - the German X-ray astronomy satellite. NASA chose the instrument as the American contribution to the ROSAT shipment.

1986
AS&E introduces the revolutionary Model Z™ MICRO-DOSE® Inspection System (Z® Backscatter) which can be retrofitted to existing systems. The new technology draws attention from publications including Fortune, Discover, The New York Times, Popular Science, U.S. News and World Report, and The Wall Street Journal.

1987
The AS&E Soft X-ray Solar Research Rocket Payload and the Naval Research Laboratory Ultraviolet Spectrograph/Spectroheliograph Payload were successfully launched in sequence in December.

1989
AS&E introduces the Model 101 series of Parcel X-ray Inspection Systems.

1990
In March, AS&E's "TOSI" X-ray Inspection System (a predecessor of CargoSearch™), begins operation, scanning missiles in railroad cars in Votkinsk, Russia, to confirm Soviet compliance with the INF (Intermediate-Range Nuclear Forces) Treaty.

1992
AS&E introduces a new product, AD-ON™ (Automatic Detection of Narcotics), which is purchased by U.S. Customs later in the year.

1993
New AS&E products enter the marketplace: CargoSearch, BodySearch, and Model 66 for MailSearch™ / LobbySearch™.

1994
In November, AS&E receives a contract from ARPA (Advanced Research Projects Agency) to develop the first MobileSearch™ X-ray Inspection System. In its first six months of operation, MobileSearch enabled Mexican agents at the U.S.-Mexico border to detect and seize 168 illegal immigrants and more than 160 kilos of cocaine valued at $8 million.

1995
AS&E moves to its new headquarters at 829 Middlesex Turnpike in Billerica, Massachusetts.

1998

AS&E sells MobileSearch overseas for the first time, to a client in the Middle East.

1999
AS&E announces the receipt of two new patents: one patent for automatically detecting the presence of a concealed item within containers and other enclosures; and a patent for a tomography system that uses backscattered X-rays to determine the depth of objects within a container.

2000
AS&E continues to grow globally, as customs agencies in both the UK and Hong Kong order X-ray systems for trade fraud applications.

2001
