UVSOR-BL3U 和 BL7U 中安装了真空波荡器。由于UVSOR的改进，诸如真空波荡器之类的具有窄磁隙的插入装置已经可用。波荡器的周期长度为36/38mm，最小间隙为15mm，这使得VUV和软X射线区域具有较宽的可调性。已经估计了对存储梁的影响，特别是对电阻墙不稳定性的影响，并且发现即使在最小间隙高度下，对存储梁的干扰也可以忽略不计。
In‐vacuum undulators have been installed in the UVSOR‐BL3U and BL7U. Due to the improvement of the UVSOR, the insertion devices with narrow magnetic gaps such as the in‐vacuum undulators have become available. The undulators have the period length of 36/38mm and the minimum gap of 15mm, which results in wide tunability in VUV and soft X‐ray region. Influence on the stored beam, especially for the resistive wall instability, has been estimated and it has found that the disturbance for the stored beam can be negligible even in the minimum gap height.
