用一个600 mm长的摩根线圈测量了大型强子对撞机(LHC)低三重态超导四极磁体MQXA的四极磁场的磁心和扭角。MQXA是在室温下用交流电激励进行测量的。一个带有激光和倾斜传感器的光敏装置与摩根线圈相辅相成，用于校正其测量位置和滚动。
The magnetic center and twist angle of the quadrupole field along the superconducting quadrupole magnet MQXA for the low- triplets of the Large Hadron Collider (LHC) were measured with a Morgan coil which consists of four 600 mm long windings. The MQXA was excited with the alternating current for this measurement at room temperature. A photo-sensitive device with laser and a tilt sensor are complement the Morgan coil for correction of its measuring position and roll.
