论文摘要
在这项工作中，我们在现实世界对撞机中进行了有史以来第一次改变齿轮的演示。齿轮改变是指碰撞方案，其中撞机的每个环都存储不同的谐波数量。这些束使用不同的速度保持同步。这种系统已被理论化，但现在使用斯德哥尔摩瑞典的双静电离子环实验（Desiree）进行了证明。该实验能够证明一个换档系统，其中四束束和四束束。我们确定了一个可测量的参数，该参数显示了一个换档系统到$ 37500 $转弯的慢梁。我们还开发了有关如何控制这种系统的新见解，开辟了新的研究可能性。
In this work we perform the first ever demonstration of gear-changing in a real world collider. Gear-changing refers to a collision scheme where each ring of a collider stores a different harmonic number of bunches. These bunches are kept synchronized using different velocities. Such a system has been theorized, but has now been demonstrated using the Double ElectroStatic Ion Ring ExpEriment (DESIREE) in Stockholm Sweden. The experiment was able to demonstrate a gear-changing system, with both four on three bunches and five on four bunches. We determined a measurable parameter that shows a gear-changing system out to $37500$ turns of the slow beam. We also developed new insights into how to control this type of system, opening up new possibilities for research.
