The time-resolved change in the surface potential upon photoexcitation has been measured two $n$-type photovoltaics, Si (111) 7\ifmmode\times\else\texttimes\fi{}7 and ZnO ($10\overline{1}0$), using different laser pump-synchrotron x-ray probe methodologies. Taken together, these experiments allow dynamics of photovoltage (SPV) to be monitored over timescales subnanoseconds milliseconds. for photoinduced SPV are dramatically samples, with decay time constants 6.6 \ensuremath{\mu}s up 1.2 ms...

This report describes the conceptual design of a proposed free electron laser test facility called CLARA that will be major upgrade to existing VELA accelerator at Daresbury Laboratory in UK. able number new schemes have been but require proof principle experiment confirm they perform as predicted. The primary focus on ultra short photon pulse generation which take lasers into whole regime, enabling area science emerge.
The compact linear accelerator for research and applications (CLARA) is an ultrabright electron beam test facility being developed at STFC Daresbury Laboratory. ultimate aim of CLARA to advanced free laser (FEL) schemes that can later be implemented on existing future short-wavelength FELs. In addition, a unique provide high-quality novel concepts ideas in wide range disciplines function as technology demonstrator United Kingdom x-ray FEL facility. built three phases; the first phase, or...
A novel single-particle technique to measure emittance has been developed and used characterise seventeen different muon beams for the Muon Ionisation Cooling Experiment (MICE). The beams, whose mean momenta vary from 171 281 MeV/c, have emittances of approximately 1.5--2.3 \pi mm-rad horizontally 0.6--1.0 vertically, a horizontal dispersion 90--190 mm momentum spreads about 25 MeV/c. There is reasonable agreement between measured parameters results simulations. are found meet requirements MICE.
Abstract Chlorophyll a is the most commonly used indicator of phytoplankton biomass in marine environment. It relatively simple and cost effective to measure when compared abundance thus routinely included many surveys. Here we collate 173, 333 records chlorophyll collected since 1965 from Australian waters gathered researchers on regular coastal monitoring surveys ocean voyages into single repository. This dataset includes values as measured samples analysed using spectrophotometry,...

Abstract Accelerated muon beams have been considered for the next-generation studies of high-energy lepton–antilepton collisions and neutrino oscillations. However, high-brightness not yet produced. The main challenge acceleration storage stems from large phase-space volume occupied by beam, derived production mechanism muons through decay pions. beam can be decreased ionization cooling. Here we show that cooling leads to a reduction in transverse emittance traverse lithium hydride or liquid...
High-brightness muon beams of energy comparable to those produced by state-of-the-art electron, proton and ion accelerators have yet be realised. Such the potential carry search for new phenomena in lepton-antilepton collisions extremely high also provide uniquely well-characterised neutrino beams. A beam may created through decay pions interaction a with target. To produce high-brightness from such source requires that phase space volume occupied muons reduced (cooled). Ionization cooling...
