Potential of Compact Compton sources In the Medical Field

Abstract : Since the exceptional development of high power femtosecond lasers in the last fifteen years, the interest in Compton X-ray sources becomes very important. In particular projects aiming to provide a laboratory-size source of high power and high quality are in full development over recent years. Compton sources are based upon inverse Compton scattering of laser light against high energy electrons. In term of integrated emitted flux and brightness the most ambitious projects can be placed near the second generation radiation facilities with the very important advantage of the compactness (~100 m2) and so the possibility to be integrated in a laboratory, a museum or a hospital. In addition to their compactness and their high flux, Compton sources should have the possibility to adjust the energy of the Compton photons and to produce high energy X-ray (20-100 KeV). This makes possible a wide range of studies requiring intense monochromatic or “pink” beams at various X-ray energies. A whole series of researches using analysis techniques previously reserved to synchrotron facilities should now become accessible and feasible in a laboratory environment. After a short presentation of basic principles of a Compton compact source (CCS), the key parameters needed to produce a high quality beam will be highlighted and the current high flux CCS projects in the world briefly presented. From the specifications of the French project ThomX, the potential of applications of CCS will be discussed in the biomedical field (imaging, therapy, adjuvants tests).
