Abstract
An analysis of a scheme to induce transverse flow in the annulus between the beam tube and coils of an SSC dipole magnet is presented. Transverse, or cross flow, cooling is used to limit the temperature rise from heat sources in the beam tube. These sources include synchrotron radiation during accelerator operation, and heat leak from the magnetic measuring device inserted in the beam tube during verification and acceptance testing of collider dipole magnets. A model which describes the flow distribution within a dipole, and subsequent temperature rise of the helium, is developed and solved. Pressure drops and transverse flow rates are presented as functions of parameters which describe the relative impedance of the various flow paths through the magnet. Results show that substantial reductions in coil temperature rise occur for very small increases in overall pressure drop, for the proper set of flow path impedances.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
