Disk chopper time-of-flight spectrometer

Working on the instrument

This video was recorded on Oct, 2006 during an experiment intitled "Light-induced biological-function related dynamics in bacteriorhodopsin (purple membrane)".

The unusual 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.
