| - Un focalisateur de plasma dense (en anglais dense plasma focus, abrégé DPF), est un appareil qui, par accélération et compression électromagnétiques, donne naissance à un cordon de plasma à vie courte qui produit, grâce aux températures et densités très élevées qu'il atteint, une abondance de rayonnements multiples. Sa conception, qui date du début des années 1960, est due à la fois à l'Américain J.W. Mather et au Russe N.V. Filippov, qui l'ont inventé parallèlement et indépendamment l'un de l'autre. Une telle compression électromagnétique du plasma est appelée striction. Cet appareil est similaire au (en anglais high-intensity plasma gun device, abrégé HIPGD), qui éjecte du plasma sous forme d'un plasmoïde, mais sans striction. (fr)
- A dense plasma focus (DPF) is a type of plasma generating system originally developed as a fusion power device starting in the early 1960s. The system demonstrated scaling laws that suggested it would not be useful in the commercial power role, and since the 1980s it has been used primarily as a fusion teaching system, and as a source of neutrons and X-rays.

- (Plasma) Focus Fusion is een manier om elektriciteit op te wekken met een apparaat dat bekendstaat onder de engelse benaming Dense Plasma Focus (DPF). Voor Focus Fusion, specifiek, wordt de DPF ingezet als een kernfusie generator, waarbij gebruik wordt gemaakt van protonen en Boor-11 ionen als fusie brandstof (pB11). De pB11 fusie reactie is: Dit is een reactie. (nl)
- Focus fusion é uma abordagem alternativa para chegar ao domínio da tecnologia da fusão nuclear para fins pacíficos de geração de eletricidade. Vem sendo desenvolvida por alguns cientistas como o americano e o chileno . Para que essa fusão de hidrogênio e boro aconteça, é necessário atingir temperaturas altíssimas, da ordem de 1 bilhão de graus. Temperaturas como essa já chegaram a ser atingidas com a utilização do Dense Plasma Focus (DPF), em um experimento na Texas A&M University, no ano de 2001. (pt)

| - A dense plasma focus (DPF) is a type of plasma generating system originally developed as a fusion power device starting in the early 1960s. The system demonstrated scaling laws that suggested it would not be useful in the commercial power role, and since the 1980s it has been used primarily as a fusion teaching system, and as a source of neutrons and X-rays. The original concept was developed in 1954 by N.V. Filippov, who noticed the effect while working on early pinch machines in the USSR. A major research program on DPF was carried out in the USSR through the late 1950s, and continues to this day. A different version of the same basic concept was independently discovered in the US by J.W. Mather in the early 1960s. This version saw some development in the 1970s, and variations continue to be developed. The basic design derives from the z-pinch concept. Both the DPF and pinch use large electrical currents run through a gas to cause it to ionize into a plasma and then pinch down on itself to increase the density and temperature of the plasma. The DPF differs largely in form; most devices use two concentric cylinders and form the pinch at the end of the central cylinder. In contrast, z-pinch systems generally use a single cylinder, sometimes a torus, and pinch the plasma into the center. 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. A comprehensive review of the dense plasma focus and its diverse applications has been made by Krishnan in 2012. (en)
