The effect of azimuthal inert material on the CMS hadron calorimeter
The baseline design for the CMS hadronic calorimeter (HCAL) calls for barrel wedges subtending an azimuthal range of 1/18 of 2 {pi}. These wedges will each have about 1 cm of inert material which is required to make a self supporting structure. Therefore, it is expected that there will be about 2 cm of inert material between active elements in the CMS calorimeter. Since the inner radius of the HCAL modules is at 1.95 m, there is about 3% of the azimuth which is inert and possibly projective. Previous studies for the SDC endcap have indicated that such a level of inert material is largely benign. However, it is necessary to examine the specific case of CMS, both in the barrel and in the endcap.
