探讨了基于小型费米转子的费米斩波器阵列的概念。这种阵列的优点是即使对于非常快速运行的大面积斩波器也具有非常低的存储动能，并且出现了新的和非常灵活的聚焦方案的可能性。这项工作包括一个小电机的驱动概念的调查和精确的相位控制的设计。此外，通过FE计算优化了高旋转频率下的转子力学（应力和变形）。斩波器的概念进行了研究，一个小型的高速电机连接到转子的弹性轴。这一概念是可比的模型的“德拉瓦尔”或“Jeffcott”转子。发展从第一布局的费米转子的原型，旨在高运行速度高达1000 Hz的描述和结果的传输，阻塞和脉冲形状获得的ESS测试光束线。
The concept of the Fermi chopper array based on small Fermi rotors is explored. The advantages of such an array would be very low stored kinetic energy even for very fast running large area choppers and emerging possibilities for new and very flexible focussing schemes. The work comprises the investigation of a drive concept with a small motor and the design of a precise phase control. Further the rotor mechanics (stress and deformation) at high rotation frequencies has been optimised by FE-calculations. A chopper concept is studied with a small high speed motor connected to the rotor by means of an elastic shaft. This concept is comparable to the model of the “de Laval” or “Jeffcott” rotor.The development from a first layout of the Fermi rotor to a prototype aiming at high running speeds up to 1000 Hz is described and results for transmission, blocking and pulse shapes obtained at the ESS test beamline are reported.
