Figure 6
A simplified schematic of the experimental set-up at a synchrotron facility is shown. The broad spectrum that is produced from the undulator is filtered through a monochromator after which a slow shutter would usually be used prior to the experimental hutch. Most commonly with synchrotron experiments, the sample is continually exposed to the beam and the detector captures the data at discrete time points with an onboard electronic shutter. During experiments with biological samples, it is frequently imperative that the sample is exposed to the smallest radiation dose possible. By placing the high-speed linear VCA shutter upstream of the sample, accurate dose control is provided. |
