使用来自线扫描器的RMS光束宽度确定IHEP RFQ输出光束的相空间性质
Determining phase-space properties of the IHEP RFQ output beam using the RMS beam widths from wire-scanners
摘要：
在IHEP实验后建立了一条束线，用于晕研究。为了确定的横向发射度和椭圆参数的激光输出光束，光束尺寸数据获得的前两个14线扫描仪。采用传递矩阵法和最小二乘法建立线性方程组，并进行求解。然后将解作为多粒子模拟中的初始束流参数来检验计算方法。结果表明，模拟的均方根光束尺寸与测量位置处的测量值之间的差异小于7%，这在我们的实验中是可以接受的。
英文摘要：
A beam line is built after the IHEP RFQ for halo study. To determine transverse emittance and ellipse parameters of the RFQ output beam, beam size data obtained from the first two of 14 wire scanners are employed. By using the transfer matrix method and the least square method, a set of linear equations were set up and solved. The solutions were then applied as initial beam parameters in multi-particle simulations to check the method of calculation. It is shown that difference between the simulated RMS beam size and the measured one at the measurement location is less than 7%, which is acceptable in our experiments.
