清华大学近代物理研究所为紧凑型脉冲强子源研制了2.45 GHz电子回旋共振强流质子源和双Glaser透镜低能束流传输线。从离子源提取的强质子束通过传输线传输，以匹配下游的射频四极加速器。利用粒子模拟程序BEAMPATH对束流输运进行了模拟，并对输运线的磁场结构进行了优化。从理论和模拟两方面研究了由于空间电荷和Glaser透镜球差引起的发射度增长。结果表明，窄光束通过传输线时具有较小的像差和较好的光束质量。为了更好地匹配射频四极加速器，需要具有足够空间电荷中和的较短的传输线。
A 2.45 GHz electron cyclotron resonance intense proton source and a low energy beam transport line with dual-Glaser lens were designed and fabricated by Institute of Modern Physics for a compact pulsed hadron source at Tsinghua. The intense proton beams extracted from the ion source are transported through the transport line to match the downstream radio frequency quadrupole accelerator. Particle-in-cell code BEAMPATH was used to carry out the beam transport simulations and optimize the magnetic field structures of the transport line. Emittance growth due to space charge and spherical aberrations of the Glaser lens were studied in both theory and simulation. The results show that narrow beam has smaller aberrations and better beam quality through the transport line. To better match the radio frequency quadrupole accelerator, a shorter transport line is desired with sufficient space charge neutralization.
