Detectors and Ancillaries
The beamline consists of two experimental stations: Hutch B and Hutch C.
In Hutch B standard experiments are run. These are experiments requiring little or no modification from one user group to the next in terms of hardware setup. That limits the type of experiments to samples prepared in our standard sample holders to be measured either at ambient temperature and pressure or in our cryostat in transmission or fluorescence mode.
In Hutch C non-standard experiments may be run. This type of experiments include users having their own apparatus, e.g. sample environments or detectors. Note that the lowest energy feasible in Hutch C is the Fe K edge at 7 keV.
