A dense plasma focus (DPF) is a machine that produces, by electromagnetic acceleration and compression, a short-lived plasma that is so hot and dense that it can cause nuclear fusion and emit X-rays. The electromagnetic compression of the plasma is called a pinch. It was invented in the early 1960s by J.W. Mather and also independently by N.V. Filippov. The plasma focus is similar to the high-intensity plasma gun device (HIPGD) (or just plasma gun), which ejects plasma in the form of a plasmoid, without pinching it.

Famous quotes containing the words dense and/or focus:
“and Venus among the fishes skips and is a she-dolphin
she is the gay, delighted porpoise sporting with love and the sea
she is the female tunny-fish, round and happy among the males
and dense with happy blood, dark rainbow bliss in the sea.”
—D.H. (David Herbert)
“Let us be aware that while they preach the supremacy of the state, declare its omnipotence over individual man, and predict its eventual domination of all peoples of the earth—they are the focus of evil in the modern world.”
—Ronald Reagan (b. 1911)
