title: [A high sensitivity optical multichannel analyzer].
abstract: Noise sources of the CCD as the photoelectric detection device in an optical multichannel analyzer (OMA) were analyzed, and noise suppression methods were discussed. A high sensitivity OMA was developed successfully on the basis of the noise suppression techniques, and the 7th spectral lines of Balmer series of hydrogen and deuterium were resolved clearly by the OMA. Its sensitivity was enhanced by one order of magnitude, compared with those reported in the literatures. This OMA also showed high resolution, high precision and good reliability in the authors' experiments.
