Calculations on the STAR conventional magnet design
A thin superconducting solenoid magnet was originally planned for the STAR detector, as described in the Conceptual Design Report. The electromagnetic calorimeter (EMC) was to be mounted outside the magnet coil and inside the magnet flux return in the form of iron bars. This design had relatively little coupling of the requirements for the magnet and the EMC. After the CDR was written, it was decided to use a conventional solenoidal magnet with copper or aluminum coils instead, primarily on the basis of construction costs. The large thickness of coil material was expected to seriously degrade the calorimeter performance, so the coil was moved outside the EMC. In the process, the magnet and EMC designs became much more closely coupled. This note documents a variety of calculations related to this coupling, as well as some of the reasons for certain design parameters of both the electromagnetic calorimeter and the conventional solenoidal magnet.
