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:
“No sleep. The sultriness pervades the air
And binds the brain—a dense oppression, such
As tawny tigers feel in matted shades,
Vexing their blood and making apt for ravage.”
—Herman Melville (1819–1891)
“I don’t have any doubts that there will be a place for progressive white people in this country in the future. I think the paranoia common among white people is very unfounded. I have always organized my life so that I could focus on political work. That’s all I want to do, and that’s all that makes me happy.”
—Hettie V., South African white anti-apartheid activist and feminist. As quoted in Lives of Courage, ch. 21, by Diana E. H. Russell (1989)
