+===== FAME instruments and techniques=====
+This page describes the types of instruments and techniques used to measure the spectra appearing in SSHADE. Description items are here as they are in the SSHADE description. More details can be found on the beamlines webpages: [[http://www.esrf.eu/UsersAndScience/Experiments/CRG/BM30B|BM30 - FAME]] and [[http://www.esrf.eu/home/UsersAndScience/Experiments/CRG/bm16.html|BM16 - FAME-UHD]].
