ultra-thin window (UTW) EDS detector

ultra-thin window (UTW) EDS detector

An EDS detector that uses an organic thin film of 0.3 to 0.5 mm thickness as a window material to prevent contaminants onto a detector element.
Aluminum is evaporated on the surface of the organic thin film so as to avoid charging on the window. Compared with the beryllium window EDS detector, the ultra-thin window (UTW) EDS detector better suppresses absorption of low energy X-rays. Thus, the detector can analyze elements lighter than sodium (Na).
