Description
The Spallation Neutron Source (SNS) low-level RF (LLRF) control system currently
utilizes separate channels to process 50 MHz down-converted pulsed Cavity IF and CW
Reference IF signals. A new scheme creates pulsed Reference RF signals which are
multiplexed with pulsed Cavity RF signals near the front-end and linear accelerator
(linac) RF cavity structures. The multiplexed pulsed RF Reference/Cavity signals
are
transported to each LLRF control system via a coaxial cable and processed in a
single
channel. Implementation details and initial results are discussed.
