LABSYNC - Laboratory compact light sources

Abstract:

The need for advanced light sources is well documented by the creation of new facilities such as SOLEIL, DIAMOND, MAX IV and the upgrades of older facilities. The applications of light sources encompass all aspects of sciences spanning the fields of physics, chemistry, biology, material science, electronics and medicine. An option to provide “more light” to this community is to develop small laboratory sources beyond the standard and rotating anodes. Recently, several “small scale synchrotron” sources were proposed, whereby the most advanced system is the Mirrorcle© developed by Prof. Yamada (Japan) with three functioning systems. In this project, we will design a complete small facility around the Mirrorcle© source. The Mirrorcle© is based on two RF klystron driven microtrons to accelerate the electrons first and second to obtain a electron storage ring with constant energy (6 MeV or 20 MeV) and high current (3A). The relativistic electrons produce intense far infrared radiation (FIR) and when targets are inserted in the electron path intense soft and hard X-rays can be produced from 90 eV up to the electron energy. The first goal of this project is to complete the characterization of the full radiation spectrum generated by the Mirrorcle© . This includes parameters such as the brilliance, the beam divergence, polarization and monochromacity. The second goal is to design a specific Mirrorcle© ring with four output ports, namely a FIR port, a soft X-rays port, a hard X-rays port and one port where the full spectrum is available. This includes designing the required targets as well as internal mirrors configurations. The third goal is to design specific beam-lines for these four ports that take into account the source. Finally, two specific user stations will be designed that make use of the unique abilities offered by such a small scale source, namely a multi-diagnostic in-situ, real-time nano-material synthesis system and a medical imaging and therapy station.
