Time-Resolved Multiple-Probe Spectroscopy Facility

Time-Resolved Multiple-Probe Spectroscopy

In the next 2 years the LSF Molecular Structural Dynamics Group (MSD) will work to combine the existing Ultrafast Spectroscopy Laboratory (USL) lasers and the new ULTRA laser system to provide advanced capability for time-resolved spectroscopy.The project, nicknamed TRmPS (Time-Resolved Multiple-Probe Spectroscopy), represents a step-change in capability enabling scientists to interrogate the structural dynamics of small quantities of precious samples with unprecedented detail.

In essence TR^MPS is a femtosecond to millisecond pump probe-probe-probe... spectrometer.The ability to activate a change/chemical reaction with a single laser shot and then probe it with up to several others provides a unique means to get the most information from precious biological samples.To do this TRmPS will utilise a 1 kHz (UV to NIR wavelength) tunable ultrafast light pulse to trigger (pump) physical changes in a sample and then interrogate (probe) the progress of molecular reaction using the 10 kHz ULTRA laser.

The science programmes will be wide ranging, for example; studies to give essential insights in the design of molecular devices, the propagation of disease (including cancer and Alzheimer’s), cell signalling pathways and DNA damage-repair mechanisms. The proposal is supported by, and tailored to a wide cross-section of the STFC user community and is closely aligned with STFC strategy to develop transient spectroscopy and imaging methods.
