The system can be used to measure the offset of the beam position monitor (BPM) with respect to the magnetic center of a quadrupole. Some measurement results for HLS are given.
研究表明,随着气流马赫数的增加,吸声结构的消声系数明显下降,微穿孔板的非线性声阻和声质量修正值都略有减少。更需注意,在高速流条件下吸声结构的共振峰将会发生偏移。
It is shown that the attenuation coefficient will decrease obviously with the increase of Mach number, and the nonlinear acoustic resistance and acoustic mass will reduce slightly.
