达姆施塔特工业大学核物理研究所的超导达姆施塔特线性电子加速器（S-DALINAC）以连续波模式提供能量高达130 MeV的电子束。该加速器由7.5 MeV注入器和30 MeV主直线加速器组成，其中超导3 GHz腔在2 K的温度下运行。有了三条再循环束线，主直线加速器可以使用多达四次。为了减少能量扩散和提高能量稳定性的梁一个新的刮削系统已经开发和安装。它改变了提取光束线成一个色散守恒的弯道组成的四个偶极磁铁和三个刮刀。该系统包括在两个位置处刮除x和y晕以及改善和稳定色散部分上的能量散布。
The superconducting Darmstadt linear electron accelerator (S-DALINAC) of the Institute for Nuclear Physics at Technische Universität Darmstadt delivers electron beams in cw-mode with energies up to 130 MeV. The accelerator consists of a 7.5 MeV injector and a 30 MeV main linac where superconducting 3 GHz cavities are operated at a temperature of 2 K. With three recirculation beam lines the main linac can be used up to four times. To reduce energy spread and improve the energy stability of the beam a new scrapersystem has been developed and installed. It changes the extraction beam line into a dispersion-conserving chicane consisting of four dipole magnets and three scrapers. The system includes scraping of xand y-halo at two positions as well as improving and stabilizing energy spread on a dispersive part.
