MedAustron is a synchrotron-based particle therapy centre located in Wiener Neustadt, Austria. It features three irradiation rooms for particle therapy, where proton beams with energies up to 252.7 MeV and carbon ions of up to 402.8 MeV/u are available for cancer treatment. In addition to the treatment rooms, MedAustron features a unique beamline exclusively for non-clinical research (NCR). This research beamline is also commissioned for proton energies up to 800 MeV, while available carbon ion energies correspond to the ones available in the clinical treatment rooms. Based on the requirements for particle therapy, all irradiation rooms offer particle rates of up to 10^9 particles/s for protons and 10^7 particles/s for carbon ions. However, for research purposes, lower particle fluxes are required and were therefore commissioned for the NCR beamline. Three particle flux settings with particle rates ranging from ~2.4x10^3 particles/s to ~5.2x10^6 particles/s were established for seven proton energies below 252.7 MeV. In addition to the particle rate, the spot sizes and beam energies were measured for these settings. Furthermore, three low flux settings for 800 MeV protons with particle rates ranging from ~2x10^3 particles/s to ~1.3x10^6 particles/s were commissioned. Since the commissioned low flux settings are in a regime well below the limits of the available standard beam diagnostics, setting up the beam under these new operational conditions entirely relied on the use of external detectors. Furthermore, a beam position measurement based alignment without using the standard beam profile monitors was performed for 800 MeV protons.

Design, Installation, and Initial Commissioning of the MTA Beamline
一个新的实验区,旨在开发,测试和验证使用400兆电子伏费米实验室直线加速器质子束的μ子电离冷却设备已经完全安装,目前正在调试。最初,该区域用于MUCOOL研发计划的液氢吸收剂的低温测试,现在,用于吸收剂的高功率束流测试,存在磁场的高梯度射频腔(包括充气腔)和其他原型μ子冷却装置。为μ子设施开发的实验方案涉及收集、捕获和冷却大发射率、高强度μ子束--约10**13 μ子,因此该设备的最终测试需要完整的直线加速器束,即1.6 x 10**13 p/脉冲。为了支持μ子冷却设施,这条新的初级束线直接从直线加速器提取束流并将其传输到测试设施。MuCool设施的设计概念来自早期的提案,但需要进行修改以适应高强度束流,低温和冷却实验规模的增加。此外,提供精确线的不同操作模式结合了专门的部分并利用直线加速器束参数的测量。本文报告的MuCool光束线的技术细节,这两种模式。
