Determining Beam Parameters in a Storage Ring with a Cylindrical Hodoscope using Elastic Proton-Proton Scattering

The EDDA-Detector at the Cooler-Synchrotron COSY/J\"ulich has been operated with an internal CH\(_2\) fiber target to measure proton-proton elastic scattering differential cross sections. For the data analysis knowledge of beam parameters, like position, width and angle, are indispensable. We h...

Summary:The EDDA-Detector at the Cooler-Synchrotron COSY/J\"ulich has been operated with an internal CH\(_2\) fiber target to measure proton-proton elastic scattering differential cross sections. For the data analysis knowledge of beam parameters, like position, width and angle, are indispensable. We have developed a method to obtain these values with high precision from the azimuthal and polar angles of the ejectiles only, by exploiting the coplanarity of the two final state protons with the beam and the kinematic correlation. The formalism is described and results for beam parameters obtained during beam acceleration are given.
