Calorimeter analysis at the DELPHI experiment
2000 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This master's thesis discusses a study of the background in the DELPHI calorimeters together with an evaluation of a Monte Carlo simulation of a counter detector connected to one of the calorimeters, called the veto counter. A new calorimeter prototype will be discussed as well. The background study was made by using a so-called random trigger. The random trigger is well suited for this purpose and the study is of special interest for the STIC calorimeter, which suffers a lot of background since it is placed closest to the beam pipe. The evaluation of the veto counter simulation was made to see if a recently improved Monte Carlo simulation was accurate enough to be used in a real physics analysis.
