One of five channels of the current passive RF
system. The main tuner is used to keep a preset cavity
Similar manufacturing proceedures were used for the
1.5GHz cavities of ALS's HHC System.
A second identical channel is used to control a second tuner in the current passive system. See first figure on this page.
