Sample Holders

MEX2 sample holders are different to MEX1.

• Fluorescence and drain current measurements: MEX2 has adopted the magnetic mounting ruler type sample holder (“sticks”) used on SXR fast NEXAFS chamber (Photos a and b). SXR sticks are interchangeable on MEX2, with the exception that on MEX2, samples may be mounted on both sides of the stick. The most convenient method of mounting most samples for fluorescence and drain current measurements is to stick them to the ruler with double sided Carbon tape (black strips on ruler b). To visualize the beam, the first ~ 7 mm of the ruler will be left blank for the adhesion of a white film (Photos b and d) that glows when struck with X-rays. See Figure e) below for more detail.

Carbon tape and fluorescent paper are available at the beamline.
