Mammography with synchrotron radiation.

Radiology, 1995
To determine the feasibility of using synchrotron radiation (SR) in diagnostic mammography.Monochromatic SR of x-ray beams of selected energies of 14-20 keV were used to obtain mammograms of surgically removed breast specimens that contained tumor nodules.

SYNCHROTRON RADIATION FOR ANGIOGRAPHY

Annual Review of Biophysics and Biophysical Chemistry, 1987
The intensity, monochromaticity, and tunability of synchrotron radiation make it well suited for transvenous coronary angiography. An X-ray imaging system based on synchrotron radiation has provided images of the coronary circulation in dogs and in human subjects.

Observation of coherent synchrotron radiation

Physical Review Letters, 1989
Coherent effects in synchrotron radiation (SR) have been observed for the first time from 180-MeV short electron bunches of 2.4 mm using the Tohoku 300-MeV Linac. The intensity of the coherent SR was about ${10}^{5}$ times as strong as that of incoherent SR in the wavelengths of 0.4--2.2 mm.

Spectroscopy with Synchrotron Radiation

1989
We describe the results of spectroscopic investigations performed on solid materials using synchrotron radiation at the Italian Synchrotron Radiation Facility PULS showing the importance of such a realization. A perspective for future developments using a third generation storage ring is also briefly outlined.

Synchrotron Radiation

2015
Synchrotron radiation is today extensively used for fundamental and applied research in many different fields of science. Its exceptional characteristics in terms of intensity, brilliance, spectral range, time structure and now also coherence pushed many experimental techniques to previously un-reachable limits, enabling the performance of experiments ...

Synchrotron radiation

2005
Electron accelerators such as synchrotrons and storage rings are the best sources of X-rays and ultraviolet photons for research and technological applications. The physical mechanisms for all these sources use relativistic effects to increase the emission and its photon energies, and require an electron (or positron) beam moving at relativistic speed.

Synchrotron-radiation laser

Physical Review Letters, 1992
A formulation to characterize stimulated emission of synchrotron radiation is presented, based on simplification of a theory developed by Sokolov and Ternov. It is shown that optical gain may be obtained up to gyration harmonics of the order of the critical harmonic number for spontaneous radiation 3${\ensuremath{\gamma}}^{3}$, where \ensuremath{\gamma}
