Lecture 36: X- Ray Photoelectron Spectroscopy (XPS)

What e- s can the Cylindrical Mirror Analyzer Detect?

• The CMA not only can detect electrons from the irradiation of X-Rays, it can also detect electrons from irradiation by the e- gun.

• The e- gun it is located inside the CMA while the X-Ray source is located on top of the instrument.

• The only electrons normally used in a spectrum from irradiation by the e- gun are known as Auger
e- s. Auger electrons are also produced by X-ray irradiation.
