Different experiments have different features, so does the optical design; however, all of them are necessary to be adjusted according to mechanism. For example, adjusting mechanism of optical element is often based on stepper motor, for stepper motor possesses high resolution ability, which can adjust mechanism to precise location. This study illustrates how motor system of our Taiwan Photon Source integrates adjusting mechanisms of stepper motor on beamline. In addition, the firmware of close-loop system is cooperated to further improve veracity of location.

We developed a white beam position detector to be applied in beamlines with bending magnets. By 0.1 mm light-receiving opening, the beam is split and converted to a photocurrent intensity which can be used to detect the size and position of the beam is less than or equal to 50 mm, and to locate the positions of the beamline components. This is a stop-beam measurement method, so it cannot be used to monitor the beam in real time. The motorized stage of the detector has a range of motion up to ± 25 mm with position accuracy not more than 1 micrometer and vacuum capability not more than 5 × 10 -10 Torr, which is compatible with ultra-high vacuum environments. In addition, taking the thermal load 62.89 W of the TPS 02A beamline as an example, the thermal deformation of the analog detector opening lead to a result that the measured value will have a maximum of 2 micrometer from the center of the beam. Finally, and the whole system has been successfully applied in the TPS 02A beamline.all features are verified and the performance meets the requirements, Besides the positioning tasks of Mask and Slits1 was completed and the position change of the light source was detected.
