Emittance is a property of a charged particle beam in a particle accelerator. It is a measure for the average spread of particle coordinates in position-and-momentum phase space and has the dimension of length (e.g., meters) or length times angle (meters times radians). As a particle beam propagates along magnets and other beam-manipulating components of an accelerator, the position spread may change, but in a way that does not change the emittance. If the distribution over phase space is represented as a cloud in a plot (see figure), emittance is the area of the cloud. A more exact definition handles the fuzzy borders of the cloud and the case of a cloud that does not have an elliptical shape.
A compact pepper pot emission measuring instrument of absolute flow rate calibration
This invention relates to the field of charged particle beam parameter measurement technology, and provides a compact pepper pot emittance measuring instrument with absolute current intensity calibration. It includes a "pepper pot" planar component, a fluorescent screen component, an observation window, and a camera system. The "pepper pot" planar component is integrated with a multi-layer structure, wherein the beam measurement layer uses a specially designed Faraday cylinder to directly measure beam intensity for calibration of measurement results. The fluorescent screen supports longitudinal position adjustment via a movable mounting bracket. The camera system can focus on the fluorescent screen and take pictures. This invention, through innovative structural design and dynamic calibration technology, eliminates the nonlinear distortion problem between grayscale value and beam intensity, improves measurement accuracy, achieves high-precision beam screening, improves the ability to capture weak beam signals, and can quickly calculate beam emittance. It is suitable for rapid and accurate measurement of charged particle beam emittance in fields such as particle accelerators.
