LOW PRESSURE PLASMA MODE
A helium plasma characterised by an emission spectrum dominated by the 1s3p 1Ρ1 to 1s2s 1S0 501.5nm transmission line, and a pressure less than 5x10-3 mbar. Methods and apparatus for igniting the plasma, and for using the plasma for pre-ionisation and glow discharge cleaning are also disclosed. Cett...

| description | A helium plasma characterised by an emission spectrum dominated by the 1s3p 1Ρ1 to 1s2s 1S0 501.5nm transmission line, and a pressure less than 5x10-3 mbar. Methods and apparatus for igniting the plasma, and for using the plasma for pre-ionisation and glow discharge cleaning are also disclosed.
Cette invention concerne un plasma d'hélium caractérisé par un spectre d'émission dominé par la raie d'émission 1s3p1Ρ1 à 1s2s1S0 501,5 nm, et une pression inférieure à 5x10-3 mbar. L'invention concerne en outre des procédés et un appareil pour allumer le plasma, et pour utiliser le plasma pour une pré-ionisation et un nettoyage par décharge luminescente. |
