摘要:

新的晶体技术--基于薄直板的弯曲条阵列和扇形反射器--已被用于U-70加速器中能量为50 GeV和1.3 GeV的循环束的提取和准直研究。它示出,新的设备可以有效地引导光束在很宽的能量范围内。对于能量为50 GeV的质子,提取和准直效率达到90%左右,这是该方法的最高记录。与通常的一级准直方案相比,在应用不同晶体的加速器中也观察到粒子损失减少2-3倍。

英文摘要:

New crystal technique - array of bent strips and a fan-type reflector, based on thin straight plates - have been used for research of extraction and collimation a circulating beam in the U-70 accelerator at the energy 50 GeV and 1.3 GeV. It is shown, that new devices can effectively steer a beam in a wide energy range. For protons with energy 50 GeV efficiency of extraction and collimation about 90 % has been achieved which is record for this method. Reduction of particle losses in 2-3 times was observed also in accelerator at application of different crystals in comparison with the usual one-stage collimation scheme of beam with a steel absorber.
