History The Plasma Window was invented at Brookhaven National Laboratory[5] by Ady Hershcovitch and patented in 1995. [6] Further inventions using this principle include the Plasma Valve in 1996. [7] Plasma valve A related technology is the plasma valve, invented shortly after the plasma window. A plasma valve is a layer of gas in the shell of a particle accelerator. The ring of a particle accelerator contains a vacuum, and ordinarily a breach of this vacuum is disastrous. If, however, an accelerator equipped with plasma valve technology breaches, the gas layer is ionized within a nanosecond, creating a seal that prevents the accelerators recompression. This gives researchers time to shut off the particle beam in the accelerator and slowly recompress the accelerator ring to avoid damage.
