As part of the NOvA upgrades in 2012, the Recycler was repurposed as a proton stacker for the Main Injector with the aim to deliver 700 kW. Since January 2017, this design power has been run routinely. The steps taken to commission the Recycler and run at 700 kW operationally will be discussed. Major improvements include a new collimation system to control transverse losses and diode damper system to damp the resistive wall instability during slip-stacking. Plans for future running will also be discussed.

使用费米实验室回收器中的质子堆叠进行高强度操作，以提供700 kW的120 GeV质子束

作为2012年NOvA升级的一部分，回收机被重新用作主要喷油器的质子堆叠器，旨在提供700 kW的功率。自2017年1月以来，此设计功能已定期运行。将讨论调试回收器并以700 kW运行的步骤。重大改进包括用于控制横向损耗的新准直系统和用于抑制滑移堆叠过程中电阻壁不稳定性的二极管阻尼器系统。还将讨论将来的运行计划。
