摘要:

磁齿槽效应的发展是质子改进计划(PIP)中费米实验室助推器升级的一部分。助推器将发送2.25E17质子/小时,这几乎是目前通量的两倍,1.4E17质子/小时到主注入器(MI)和回收器(RR)。提取喷射器间隙必须与MI和RR注入桶同步,以避免在提取和注入喷射器的上升沿处的射束损失。磁齿槽效应是利用偶极子校正器产生的磁场来控制旋转频率和间隙的位置,而径向位置反馈则使束流保持在中心轨道上。预期新的齿槽效应将减少由于轨道变化引起的束损失,并且在产生间隙时减少束能量损失。本文将讨论磁定位系统的发展进展。

英文摘要:

The development of magnetic cogging is part of the Fermilab Booster upgrade within the Proton Improvement Plan (PIP). The Booster is going to send 2.25E17 protons/hour which is almost double the present flux, 1.4E17 protons/hour to the Main Injector (MI) and Recycler (RR). The extraction kicker gap has to synchronize to the MI and RR injection bucket in order to avoid a beam loss at the rising edge of the extraction and injection kickers. Magnetic cogging is able to control the revolution frequency and the position of the gap using the magnetic field from dipole correctors while radial position feedback keeps the beam at the central orbit. The new cogging is expected to reduce beam loss due to the orbit changes and reduce beam energy loss when the gap is created. The progress of the magnetic cogging system development is going to be discussed in this paper.
