As I understand it the source is based on a small low energy electron storage ring and a high average power laser. The photons from the laser receive extra energy by scattering from the electrons (the inverse Compton effect). The energy of the electrons is chosen to give x-rays of our desired wavelength. The set up is designed to give a high average photon flux/brightness. Other types of inverse Compton facilities are based on linacs (for example) and short pulse lasers to give a high peak flux of x-rays (short intense pulse) but with a lower repetition rate. I believe the aim of Compact Light Source is to get performance similar to a bending magnet on a (second generation?) storage ring. This could sell provided the cost is reasonable. I presume they are building/testing their prototype and are not releasing too much information at this stage. I have just looked at their web site and there are some details there (http://www.lynceantech.com/sci_tech_cls.html). Those thinking of upgrading their data collection facilities would clearly like to know when the source would be available. I am afraid I can't help here.

Lyncean Technologies claims to manufacture room size x- ray source which can provide x-rays comparable in quality and flux to those available at synchrotons. Yet their website has little technical information. I will highly appreciate if any one can provide me with some insights about this new development with best wishes Ranvir __________________________________________________ Do You Yahoo!?
