== Plasma valve ==
A related technology is the <!-- [[plasma valve]] relink if separate article has been created -->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 accelerator's recompression. This gives technicians time to shut off the particle beam in the accelerator and slowly recompress the accelerator ring to avoid damage.
