This capital bid is for items that will enhance the research being carried out by the group. The Digital DAQ system will be attached to the Liverpool detector characterisation scanning system which is fundamental to the academic and applications research work carried out by he group which has the aim to produce better gamma-ray detectors.The SAGEWELL detector is a new type of gamma-ray detector. It has both high efficiency and excellent energy resolution. The novel electric field configuration means that it is an ideal detector to be based in our laboratory which when used with the detector characterisation scanning system will allow us to better understand and model the electric fields within the crystal and to determine the effect of parameters such as impurity concentrations and temperature dependence of the electron and hole mobility. Improvement of the modelling capability is an important part of our academic research (e.g. AGATA, SIGMA) and the applications work where improved spectral response for the measurements such as decommissioning and environments assay is part of our research programme.The Matisse dye laser will provide stable, narrow linewidth, laser light across a broad range of wavelengths for high resolution optical spectroscopy. This will revolutionise the university's infrastructure and will match well the recently purchased second harmonic generator, to be applied to fundamental research into nuclear structure. Adoption of this modern and popular system will also allow skills to be transferred between collaborations and indeed to optics and photonics industries.The triggerless data acquisition system pioneered by us requires an upgrade of the central clock distribution system in the form of new state-of-the-art metronome/clock distributor cards (MCD) for use in nuclear physics experiments. The development of these cards was funded by STFC through the 2014-2017 consolidated grant and prototypes were designed, delivered and tested by our collaboration. We will now construct 21 production units for use in the University of Jyväskylä (18 units) and ISOLDE at CERN (3 units). This will allow us to pursue pioneering research well aligned with the research goals set by the UK NP Advisory Panel.
