|Abstract:||Avalanche detection of a laser enhanced ionization (LEI) signal has been studied in a resonance ionization detector (RID) cell containing mercury vapour at room temperature. An avalance multiplication factor of more than 8000 was achieved. The limit of detection of Hg resonance radiation (lambda = 253.7 nm) was at the level of 0.5 quantum during the lifetime of the excited 63P01 state. Detection of radiation from a conventional cw Hg discharge lamp source with a signal to noise ratio of more than 10 4 has been achieved.|
