Superconducting detector magnets: alternatives and choices

Detectors for colliding beam experiments will require magnetic fields in order to detect and analyze charged particles. Often it is best to use a superconducting magnet to generate this field. Several kinds of superconducting magnets can potentially be used in the charged particle detectors. The solenoid appears to be the best type of superconducting magnet for this type of physics. Three kinds of superconducting solenoids can be used. The kind of solenoid magnet to be used in the experiment is dictated by the physics outside of the magnet coil. A low current density conventional solenoid and two types of high current density magnets which permit physics to be performed outside the magnet are discussed
