论文摘要
在2020 - 2021年，在PIP-II注射器测试设施（PIP2IT）进行了一系列光束动态研究，该研究已构建了在Fermilab建造的PIP-II LINAC的前端概念。 PIP2IT由30盎司H离子源，2 m长的低能光束传输（LEBT），一个2.1-MEV CW RFQ，然后是10米中型能量束传输（MEBT），2个Cryomodules将光束加速至16 MEV，并带到16 MEV，并带有高含量的传输（HEBT）。本文介绍了光束动力学 - 在PIP2IT上执行的相关测量值，例如带有Allison扫描仪的Twiss参数，沿喷射器的束信封以及横向和纵向RMS发射率重建。将这些测量值与梁动力学代码tracewin的预测进行了比较。
A series of beam dynamic studies were performed in 2020-2021 at the PIP-II Injector Test Facility (PIP2IT) that has been built to validate the concept of the front-end of the PIP-II linac being constructed at Fermilab. PIP2IT is comprised of a 30-keV H- ion source, a 2 m-long Low Energy Beam Transport (LEBT), a 2.1- MeV CW RFQ, followed by a 10-m Medium Energy Beam Transport (MEBT), 2 cryomodules accelerating the beam to 16 MeV and a High-Energy Beam Transport (HEBT) bringing the beam to a dump. This paper presents beam dynamics - related measurements performed at PIP2IT such as the Twiss parameters with Allison scanners, beam envelopes along the injector, and transverse and longitudinal rms emittance reconstruction. These measurements are compared with predictions from the beam dynamics code Tracewin.
