CMS is one of the major detectors in the Large Hadron Collider (LHC) and it isbuilt to check postulations of the standard model, especially, the Higgs mechanism. TheHF calorimeter is part of the CMS detector to detect forward jets. The HF Forward Calorimeter is designed as a quartz fiber calorimeter (QFCAL). It is important tounderstand the energy resolution and response of the HF calorimeter.In this work, the test beam data taken during the HF Test Beam 2004 period areanalyzed using "root", an Object Oriented Data Analysis Framework. The energy resolutions and energy response values of the wedge 2-13 of the HF Calorimeter withelectrons are determined as a function of both tower number and beam energy. Theresults show that the energy resolution values are reasonable for the HF Calorimeter andget better with high PMT gains. But for energy response, some deviation from the flat response is determined.
