In modern industry, exponential growth plotted against linear scale is often called Moore’s law. In fact density of IC followed an exponential growth owing to incredible efforts. In a similar fashion, we see an exponential trend in brilliance of synchrotron radiation that may look like never-ending. Sustainability in brilliance of light source can be called synchrotron Moor’s law. Note, however, that straight line in exponential scale actually consists of multiple lines, i.e., different devices based on different principles, such as bending magnet, wiggler, undulator, Free Electron Laser (FEL) and Energy Recovery Linac (ERL)1. Gordon E. Moore says, however, “No exponential law lasts forever”. Indeed, silicon technology which prospered for many decades is now seriously endangered. Leakage current in nm-scale MOS devices became dependent on tunneling which is governed by intrinsic (dielectric) property. Moore’s law Fig.1 Brilliance of synchrotron plotted against time which shows a Moore’s law-like exponential growth. FEL • P. Montano & H. Oyanagi, MRS BULLETIN 24 (1999) 13. ERL
