High Pressure Cell for Simultaneous Dielectric and QENS/INS going up to 500 MPa

The main technical aim of this LTP is to design, manufacture and test a high pressure (500~MPa) cell for simultaneous dielectric and neutron spectroscopy in collaborations with the SANE group of the ILL. This proposed cell will be a new and unique tool for studying a variety systems with dynamics on a large range of time scales. In order to study the broad range of dynamics coming all the way from the ps range to the ks it is necessary to combine complementary techniques; dielectric spectroscopy and neutron spectroscopy being two of the most important tools. Pressure has proven to be a strong tool in separating different processes as well as in understanding how they are controlled by temperature vs. volume effects. The aim of this proposal is to be able to perform the dielectric and neutron spectroscopy simultaneously while controlling both T and p. The cell will be a strong tool particularly for physically and chemically unstable systems, e.g. biological samples, samples that undergo chemical reactions such as polymerization or systems undergoing a phase transition. We will use the cell for glassy systems while they undergo physical aging.
