Description

Laser produced plasmas (LPPs) are key components for atomic and ionic spectroscopy. They act as sources of neutrals and ions, and of radiation to probe their structure.
Both emission and absorption spectroscopy are facilitated using LPPs. As part of the HEAVYMETAL project, the team at UCD will develop new configurations of LPPs to enhance, and perhaps optimise, populations of desired species.
We will probe these with established and new spectroscopic techniques, ranging from the soft x-ray to the near infra-red, with the explicit intention of contributing to our understanding of Kilonova observations.
In this talk I will introduce the UCD group and outline our plans for research over the next few years. I will present very preliminary, as yet not analysed, experimental spectra of 4th & 6th row elements.
