Argon flash light source

Japanese: アルゴンフラッシュ光源 - あるごんふらっしゅこうげん
Argon flash light source

… Discharge tubes (xenon flash lamps) filled with monatomic gases such as xenon, which have good luminous efficiency, are also used as bright instantaneous light sources, and luminous times of about 10 −6 s have been reported. There is also an argon flash light source that uses a shock wave generated in argon by a powerful explosive, and utilizes the strong luminescence of the compressed argon behind the wave front, which is heated to tens of thousands of degrees. By changing the length of the argon layer through which the shock wave propagates, luminous times of 10 −4 to 10 −7 s can easily be obtained. …

… 発光効率のよいキセノンなどの単原子気体を封入した放電管(キセノンフラッシュランプ)も明るい瞬間光源として利用され,発光時間10-6s程度のものが報告されている。また,強力な爆薬によってアルゴン中に衝撃波を発生させ,波面背後の圧縮され数万度の高温となったアルゴンの強い発光を利用するアルゴンフラッシュ光源もある。衝撃波が伝搬するアルゴン層の長さを変えることにより10-4~10-7sの発光時間が容易に得られる。…
