Abstract:

Beam parameters at the face of crystal part of HyCal detector were studied. The goal of this study was to determine the beam position and entrance angles at the calorimeter as well as its spatial and angular divergence. This note is divided into two parts. The first describes the method used in the analysis of beam stability as well as its results and the other presents the results of the beam divergence study. This study however needs further work. The beam position from 2C21A BPM needs to be incorporated in the position fits.
