研制了一种基于多极单块磁铁的力抵消系统的变间隙波荡器。LCVGU没有沉重的机械框架，由于强大的吸引力，这是传统可变间隙波动器（VGU）特有的基本元件，因此预计建造和安装的成本和时间将显着减少; MMM以具有成本效益的方式抵消强大的吸引力。两个原型LCVGU的机械测试和磁场测量结果与建议的力消除系统配备了显示与传统的VGU的性能相当。由AIP出版社出版。
A lightweight-compact variable-gap undulator (LCVGU) having the force-cancellation system based on the multipole monolithic magnets (MMMs) has been developed. The LCVGU is free from the heavy mechanical frames, which is a fundamental element specific to conventional variable-gap undulators (VGUs) because of a strong attractive force, and thus the cost and time for construction and installation are expected to be significantly reduced; the MMMs counteract the strong attractive force in a cost-effective manner. Results of mechanical tests and magnetic-field measurements of two prototype LCVGUs equipped with the proposed force cancellation system have revealed the comparable performance with the conventional VGUs.
