Does anyone know what companys have an explosively pumped flux compression generator other than Los Alamos?

Question

Explosively pumped flux compression generators are popular as power sources for electronic warfare devices known as transient electromagnetic devices that generate an electromagnetic pulse without the costs and side effects of a nuclear weapon. (Think the pinch in Ocean's 11) Basically I want to know which research laboratories have them, particularly in France.

Answer 1

E-bombs? howstuffworks says the USSR, and CIS, but gives no more precise location. Later says only US and CIS.
