At BESSY II it is demonstrated that far-infrared coherent synchrotron radiation (CSR) can be generated by a controlled, steady-state process at storage rings. As an indication for coherent emission, the radiated power grows with the square of the beam current. The spectrum was analyzed by an interferometer in the 1-mm to 0.3-mm wavelength range. The CSR was enhanced more than 3000 times above background; the incoherent radiation remained below the background level. Steady-state and bursting CSR were discriminated by time resolved analysis from micro seconds to seconds.
在德国柏林电子同步加速器（BESSY II）上已证明，在储存环中可以通过一个可控的稳态过程产生远红外相干同步辐射（CSR）。作为相干发射的一个指标，辐射功率随束流的平方增长。用干涉仪在1毫米至0.3毫米波长范围内对光谱进行了分析。CSR比背景增强了3000倍以上；非相干辐射仍低于背景水平。通过从微秒到秒的时间分辨分析区分了稳态和爆发性CSR。
