在J-PARC主环同步加速器上，研究了高功率束流运行中由于空间电荷诱导共振引起的束流横向发射度增长。在结构共振附近和非结构共振附近测量了逐圈梁的尺寸。观察到发射率的明显差异。发射度在工作调谐时增长了5倍，在前100圈内增长了1.8倍。计算结果表明，在λ区调谐有利于高强度光束的运转.的区域内的水平调谐而变化的逐匝发射度。这表明发射度增长的机制与调谐展宽分布有关。束流动力学的模拟结果，包括空间电荷效应通过粒子在细胞算法纳入令人满意的再现。为了揭示发射度增长的机制，通过模拟和解析计算评估了空间电荷对共振的影响。
Transverse emittance growth due to space-charge-induced resonance was studied for high-power beam operation in the J-PARC main ring synchrotron. The turn-by-turn beam sizes were measured near the structure resonance atand near the nonstructure resonance at. A clear difference in the emittances was observed. The emittance was observed to grow by 5 times at the operating tune, and by 1.8 times atin the first 100 turns. The results show the advantage of tuning in the region offor high intensity beam operation. The turn-by-turn emittance varied depending on the horizontal tune in the region of. This indicates that the mechanism of emittance growth is related to the tune spread distribution. The results were satisfactorily reproduced by the simulations of the beam dynamics, including the space-charge effect incorporated via the particle-in-cell algorithm. To reveal the mechanism of the emittance growth, the space-charge effects on the resonances were evaluated by simulations as well as analytical calculations.
