| Abstract | : | Installation of an Endcap Electromagnetic Calorimeter into the STAR magnet will require modifications and the addition of structures that have the potential to affect the internal magnetic field. Magnetic field calculations from a finite element analysis program are used to study a small modification to a feature in the poletip to mount the detector, the addition of magnetic steel PMT boxes to the outside of the west poletip and to set specifications on the stainless steel used in the structure of the EEMC. It is found that, in all cases, the effects on the field will be small compared to requirements on the field uniformity for tracking in the TPC.
