Momentum collimation in a high-intensity rapid cycling synchrotron (RCS) is a very important issue. Based on the two-stage collimation principle, a combined momentum collimation method is proposed and ...

Abstract: For the electromagnetic (EM) vortex imaging purposes, the sidelobe suppression and the beam collimation method in the generation of orbital angular momentum (OAM) beams is proposed. Based on ...

Abstract: With the high angle measurement precision, theodolite has been widely used in Spacecraft Assembly alignment. However, the use of theodolite is connected with manual operation and judgment of ...

In my opinion, the Bahtinov mask is one of the most useful inventions for astrophotography. The traditional use of a Bahtinov mask is for focusing a telescope only and is not used for collimation of ...

Introduction: The purpose of this study was to evaluate the effect of collimation on image quality and radiation dose to the eye lenses of the personnel involved in computed radiography of the canine ...
