Title :
The longitudinal coupling impedance of a slot on the SSC Collider liner
Author_Institution :

Abstract :
The location of a liner inside the collider beam tube is being studied at the SSC Laboratory, in order to provide a synchrotron radiation intercept and to help enhance the vacuum. There will be wake fields propagating inside the liner following the beam fields incident on the pumping holes/slots on the liner. The effect of the wake fields may be expressed through coupling impedances. This paper describes a method to evaluate the longitudinal coupling impedance of slots/holes on the liner for a large range of frequencies (0-60 GHz)
