费米实验室主注入器的束流损失控制

Beam Loss Control for the Fermilab Main Injector

Bruce C. Brown

摘要:

从2005年到2012年,费米实验室主注入器提供了120 GeV的质子束,以产生中微子束和反质子。硬件改进与改进的诊断相结合,使系统能够在400千瓦的光束功率下持续运行。损失是在或接近8 GeV的注入能量,其中95%的光束传输导致约1.5千瓦的光束损失。通过最小化和局部化损失,剩余辐射水平下降,而光束功率增加了一倍。丢失的射束被引导至准直系统或射束中止。增加了临界孔径,同时改进的仪器允许最佳地使用可用的孔径。我们将总结各种损失控制工具的影响以及主注入器中剩余辐射的现状和趋势。

英文摘要:

From 2005 through 2012, the Fermilab Main Injector provided intense beams of 120 GeV protons to produce neutrino beams and antiprotons. Hardware improvements in conjunction with improved diagnostics allowed the system to reach sustained operation at 400 kW beam power. Losses were at or near the 8 GeV injection energy where 95% beam transmission results in about 1.5 kW of beam loss. By minimizing and localizing loss, residual radiation levels fell while beam power was doubled. Lost beam was directed to either the collimation system or to the beam abort. Critical apertures were increased while improved instrumentation allowed optimal use of available apertures. We will summarize the impact of various loss control tools and the status and trends in residual radiation in the Main Injector.
