Development of a gated optical multichannel analyser for laser-plasma spectroscopy.
Master of Science thesis, Dublin City University.
An Optical Multichannel Analyser (OMA) has been
developed for the detection of radiation from
laser-produced plasmas (LPPs). The system is based on a
gated image - intensified photodiode array (PDA) Software
for the control of, and data acquisition from, the OMA
system has been developed. A high resolution (10ns) delay
generator was also designed and constructed to permit timeresolved. optical spectroscopy. The system has been tested and operated with a laser plasma source m the visible and near infra-red (NIR) spectral region (400 -> 800nm) Some initial results from preliminary experiments to
extend the usefulness of the OMA system into the vacuum-UV
(VUV) are presented.
