About the Project

Neutron scattering is a powerful technique for gaining an insight into structural and magnetic properties of materials on microscopic level. High pressure is just as powerful a tool for modifying and tuning properties of materials. However, combining the two represents a significant technical challenge. Neutron scattering requires relatively large sample volumes of several cubic millimetres and creating pressures of an order of several GPa on such samples requires rather bulky pressure cells. There is a number of different designs of pressure cells for neutron scattering but practically all of them are of clamp design, i.e. pressure can only be changed at room temperature and often in a stand-alone hydraulic press. This poses a problem if the interesting behaviour in the material to be studied is at low temperatures (as often happens to magnetic materials) - in order to change pressure the pressure cell needs to be warmed up to room temperature, the pressure cell is to be removed from the cryostat, pressure is to be changed and the cell is to be cooled down again. This process can take several hours and has to be repeated for each pressure value at which the measurement is to be done. This adds up to a significant loss of valuable beamtime during the neutron experiment.

This project is focused on developing the new type of pressure cell in which pressure can be changed at low temperature, i.e. without the need to remove the cell from the cryogenic equipment. Once the equipment and the techniques are developed they will be used for studies of various advanced magnetic materials and strongly-correlated
systems.
This is a joint Engineering postgraduate project between the Centre for Science at Extreme Conditions (CSEC) at the University of
Edinburgh and ISIS neutron source and the successful candidate is expected to spend a significant proportion of his/her time working at ISIS. For more information about the instrumentation development group at CSEC and ISIS neutron facility please see the following pages:

Funding Notes

Eligibility and qualifications:
Applicants must be of outstanding academic merit and hold (or be expected to gain) a first class honours degree in Physics or Engineering. This project will lead to the award of PhD in Engineering and will be of interest to students with background in Engineering who are interested in Physics, and equally to students with first degree in experimental Physics and interest in instrumentation development. The project involves training on a number of subjects and gaining transferrable skills in computer aided design and finite element analysis.
