超强永磁四极杆（PMQ）因其紧凑和低功耗而成为线性对撞机最终聚焦透镜的候选之一。我们的PMQ第一个制造的原型实现了300T/m的超强磁场梯度，总磁体半径为100mm，孔径半径为7mm，但其缺点是其固定强度。因此，第二个强度可调的PMQ原型被制作出来。其强度调节基于“双环结构”，分别旋转细分磁体片。第二个原型正在测试中。一些早期结果已经公布。
A superstrong permanent magnet quadrupole (PMQ) is one of the candidates for the final focus lens for the linear collider because of its compactness and low power consumption. The first fabricated prototype of our PMQ achieved a 300T/m superstrong field gradient with a 100mm overall magnet radius and a 7mm bore radius, but a drawback is its fixed strength. Therefore, a second prototype of PMQ, whose strength is adjustable, was fabricated. Its strength adjustability is based on the "double ring structure", rotating subdivided magnet slices separately. This second prototype is being tested. Some of the early results are presented.
