IN5 - Light-induced biofunction

A series of short movies showing how neutron experiments are prepared or performed. Some of these movies have an historical interest since they captured important moments in the life of the ILL.

Light-induced biological-function related dynamics in bateriorhodopsin

IN5 is a general purpose direct-geometry disk-chopper time-of-flight spectrometer. It is used to study low-energy transfer processes as a function of momentum transfer. It is often used for quasi-elastic scattering in solids, liquids, molecular crystals and even biological samples.

The video below was recorded on Oct, 2006 during experiment 8-04-406: "Light-induced biological-function related dynamics in bacteriorhodopsin (purple membrane)". The environment setup comprises a powerful pulsed laser which illuminates the sample to trigger the light-induced transition specific to this system. This is phase-locked with a controllable delay to the incident neutron pulses at the sample.

Note: the laser pulses being shorter than the image rate, they are not shown here at there true speed and period.
