About Us

Our approach to protecting people and systems always begins with understanding the threat itself.  For instance, in the 1970’s, our legacy company, Physics International began research into how best to simulate the Electromagnetic Pulse (EMP) generated by a nuclear weapon detonated in space.  This research led to the construction of more than two dozen EMP simulation facilities for the U.S. and our allies.  These facilities allow mission-critical assets to be tested against this threat without the need for a nuclear detonation.  To successfully simulate EMP, we know how to store and discharge extremely large amounts of electrical power in extremely short pulses.  This expertise has led to ATI’s work in support of the Electromagnetic Aircraft Launching System (EMALS) and other systems which require storage and prompt discharge of electrical energy.

Another spin off of our nuclear weapons effects work has been the development of linear accelerators (LINACs).  Originally intended to simulate the high-energy electrons resultant from a nuclear detonation, our work in this area has led to ATI’s robust electron-beam sterilization systems, which ensure sterility during medical device manufacturing process, and our world-renowned Flash X-ray business, which supports non-destructive testing for industrial use. 

In addition to such spin-off applications, we apply our threat modeling expertise directly to learning how to mitigate the threat itself.  While supporting the U.S. government’s EMP threat definition, we developed methods to shield critical systems from EMP.  Our ancestor Jaycor provided the first High-Altitude EMP (HEMP) shielding technologies to mission-critical U.S. assets; by the 1980s, Jaycor was providing support to the evolving Military Standards specifying such shielding.  We continue to protect these mission-critical systems today.

Our work in modeling the physical environment has also provided insights into personal protective gear for U.S. troops, how to make their tactical vehicles safer in the event of Improvised Explosive Device (IED) attack, and the prevention of overuse injury due to repetitive stress.  Arising from the need to understand how ballistic missiles could survive underwater launch, we’ve adapted our physics-based simulation software to model the human body’s response to harsh environments.
