Not sure why this is in the AA forum, but...
The one usage of EMP that I know of is electromagnetic pulse. Electromagnetic weapons use such EMPs to damage other electronic devices. EMPs are also byproduct of nuclear weapon detonation.
I have no idea if this has anything to do with what you encountered and why the TSA employees were cheering. Maybe something they were screening was interfering with their equipment?
