Relaxation time versus temperature of protein hydration water in Lysozyme measured by neutron scattering.
The relaxation time obtained with the standard quasi-elastic neutron scattering protocol by Chen and co-workers3 (blue dots) and the one obtained by RENS protocol37,38 (red dots) are shown. The RENS data have been obtained by collecting the elastic neutron-scattering intensity with five different neutron spectrometers working at 5 different energy resolution: 0.65 μeV for SPHERES at MLZ, 0.8 μeV for HFBS at NIST, 1 μeV for IN10, 8 μeV for IN13 and 200 μeV for IN4 at ILL. In the current work we present an instrument-concept able to collect RENS-like data and give then direct access to the system relaxation time. The main target will be complex (bio-) systems.
