摘要

费米实验室NuMI-MINOS实验的120 GeV主质子束线将传输有史以来最强烈的高能束之一。在与对撞机程序并行运行的情况下，费米实验室主注入器80%的强度能力可以发送到NuMI。与残留活动、设备损坏和地下水辐照有关的辐射安全是一个主要问题。一个特别的挑战是，这种光束将被输送到并瞄准在含水层地区的岩石中挖掘的洞穴。在辐射模拟程序MARS中建立了一个光束线模型，包括传输元件和挖掘的外壳。该模型已被用于确定允许梁损失的极限，并研究失稳和各种破坏类型的影响。给出了用该模型得到的一些结果。

Modeling of the primary proton beamline of the Fermilab NuMI project

The 120 GeV primary proton beamline for the NuMI-MINOS experiment at Fermilab will transport one of the most intense high-energy beams ever constructed. In parallel operation with the Collider program, 80% of the intensity capability of the Fermilab Main Injector can be sent to NuMI. Radiation safety pertaining to residual activity, damage of equipment and irradiation of groundwater is a primary concern. A particular challenge is that this beam will be transported to and targeted in a cavern excavated in rock in an aquifer region. A model of the beamline, including transport elements and excavated enclosures, has been built in the radiation simulation program MARS. This model has been used to determine limits for allowable beam loss, and to study effects of instabilities and of various failure types. Some results obtained with this model are presented.
