论文摘要
电离曲线监测器（IPM）被广泛用于粒子加速器中，以快速评估高能光束的参数。由于空间充电效应和其他几种物理原因以及仪器效应，测得的IPM轮廓与梁的轮廓不同。经验数学模型通常用于重建概况。在这里，我们根据IPMS中次要的空间充电动力学提出适当的校正算法。我们还从实验测量的概况中证明了光束尺寸重建的效率，并讨论了限制IPM精度的实际方面。
Ionization profile monitors (IPMs) are widely used in particle accelerators for fast evaluation of parameters of high energy beams. Due to the space-charge effects and several other physical reasons, as well as due to instrumental effects, the measured IPM profiles differ from the those of the beams. Empirical mathematical models are commonly used for reconstruction of the profiles. Here we present proper correction algorithm based on the space-charge dynamics of the secondaries in IPMs. We also demonstrate efficiency of the beam size reconstruction from experimentally measured profiles and discuss practical aspects limiting the IPM accuracy.
