Synchrotron Mossbauer spectroscopy using high-speed shutters.
- X-Ray Science Division
A new method of performing Moessbauer spectroscopy with synchrotron radiation is demonstrated that involves using a high-speed periodic shutter near the focal spot of a microfocused X-ray beam. This fast microshuttering technique operates without a high-resolution monochromator and has the potential to produce much higher signal rates. It also offers orders of magnitude more suppression of unwanted electronic charge scattering. Measurement results are shown that prove the principle of the method and improvements are discussed to deliver a very pure beam of Moessbauer photons (E/{Delta}E {approx_equal} 10{sup 12}) with previously unavailable spectral brightness. Such a source will allow both Moessbauer spectroscopy in the energy domain with the many advantageous characteristics of synchrotron radiation and new opportunities for measurements using X-rays with ultra-high energy resolution.
