Pinch Production and Types
Pinches are created in the laboratory in equipment related to nuclear fusion, such as the Z-pinch machine, and high-energy physics, such as the dense plasma focus. Pinches may also become unstable, and generate radiation across the electromagnetic spectrum, including radio waves, x-rays and gamma rays, and also neutrons and synchrotron radiation. Types of pinches, that may differ in geometry and operating forces, include the cylindrical pinch, inverse pinch, orthogonal pinch effect, reversed field pinch, sheet pinch, screw pinch (also called stabilized z-pinch, or θ-z pinch), theta pinch (or thetatron), toroidal pinch, ware pinch and Z-pinch.
Pinches are used to generate X-rays, and the intense magnetic fields generated are used in electromagnetic forming of metals (they have been demonstrated in crushing aluminium soft drinks cans). They have applications to particle beams including particle beam weapons, and astrophysics.

Famous quotes containing the words pinch, production and/or types:
“So-called Western Civilization, as practised in half of Europe, some of Asia and a few parts of North America, is better than anything else available. Western civilization not only provides a bit of life, a pinch of liberty and the occasional pursuance of happiness, it’s also the only thing that’s ever tried to. Our civilization is the first in history to show even the slightest concern for average, undistinguished, none-too-commendable people like us.”
—P.J. (Patrick Jake)
“The development of civilization and industry in general has always shown itself so active in the destruction of forests that everything that has been done for their conservation and production is completely insignificant in comparison.”
—Karl Marx (1818–1883)
“... there are two types of happiness and I have chosen that of the murderers. For I am happy. There was a time when I thought I had reached the limit of distress. Beyond that limit, there is a sterile and magnificent happiness.”
—Albert Camus (1913–1960)
