ICCD CAMERA to Dublin Institute Technology Marlborough Street, Dublin 1,

Tender description

DIT Marlborough Street requires the supply of an ICCD Camera to the BioPlasma Research group of the School of Food Science and Environmental Health (“the School”). In two-dimensional ICCD imaging of plasma spectral emission, will be used to do a Phase resolved optical emission spectroscopy (PROES). PROES is an important tool for developing fundamental understanding of plasmas, but also has potential for development as a process sensor. The glass/quartz shell transparency issue is one of the biggest disadvantages to any optically based monitoring technique due to the formation of coatings on viewports during plasma processes. This is not an issue for PROES since the time scale is different (ns) to that of OES (ms or s). PROES has time resolution on a ns scale, it is particularly sensitive to energetic electrons and can be adapted for industrial needs, i.e., it has a low cost per lambda and high sensor capabilities. PROES will be used for analysing atomic spectral lines and molecular bands in the discharge spectrum. Consequently, the relative importance of particle (ions, neutrals, radicals, excited molecules) versus radiative (mostly UV) processes in the optimised discharge regime will be identified and the role of key reactive products in biological interactions in correlation with key system parameters will be characterised.
