Explosively pumped flux compression generator
open-in-new
<p>An explosively pumped flux compression generator (EPFCG) is a device used to generate a high-power <a href="/facts/Electromagnetic_pulse/fBXSm3Hf">electromagnetic pulse</a> by compressing <a href="/facts/Magnetic_flux/jQMVxrnD">magnetic flux</a> using <a href="/facts/Explosive/sUme5Pp8">high explosives</a>. </p><p>EPFCGs are physically destroyed during operation, making them single-use. They require a starting <a href="/facts/Electric_current/Dc1xdnUX">current</a> pulse to operate, usually supplied by <a href="/facts/Capacitor/hyowqv7n">capacitors</a>. </p><p>Explosively pumped flux compression generators are used to create ultrahigh <a href="/facts/Magnetic_field/Ta8Ev588">magnetic fields</a> in physics and materials science research and extremely intense pulses of <a href="/facts/Electric_current/Dc1xdnUX">electric current</a> for <a href="/facts/Pulsed_power/BTJN8xg5">pulsed power</a> applications. They are being investigated as power sources for <a href="/facts/Electronic_warfare/c6XGz9y0">electronic warfare</a> devices known as transient electromagnetic devices that generate an <a href="/facts/Electromagnetic_pulse/fBXSm3Hf">electromagnetic pulse</a> without the costs, side effects, or enormous range of a <a href="/facts/Nuclear_electromagnetic_pulse/b8Y2vvpW">nuclear electromagnetic pulse</a> device. </p><p>The first work on these generators was conducted by the <a href="/facts/VNIIEF/oBMF2dKh">VNIIEF</a> center for nuclear research in <a href="/facts/Sarov/R6rkT844">Sarov</a> in the <a href="/facts/Soviet_Union/m7wWsPto">Soviet Union</a> at the beginning of the 1950s followed by <a href="/facts/Los_Alamos_National_Laboratory/tlrLkV7r">Los Alamos National Laboratory</a> in the <a href="/facts/United_States/P0sCdLe5">United States</a>. </p>
