The Spallation Neutron Source RF Reference System
/ Piller, Maurice ; Champion, Mark ; Crofford, Mark ; Doolittle, Lawrence ; Ma, Hengjie
The Spallation Neutron Source (SNS) RF Reference System includes the master oscillator (MO), local oscillator(LO) distribution, and Reference RF distribution systems. Coherent low noise Reference RF signals provide the ability to control the phase relationships between the fields in the front-end and linear accelerator (linac) RF cavity structures. [...]

Operational Experience with the Spallation Neutron Source High Power Protection Module
/ Crofford, Mark ; Champion, Mark ; Kasemir, Kay-Uwe ; Ma, Hengjie ; Piller, Maurice
The Spallation Neutron Source (SNS) High Power Protection Module provides protection for the High Power RF Klystron and Distribution System and interfaces with the Low-Level Radio-Frequency (LLRF) Field Control Module (FCM). The fault detection logic is implemented in a single FPGA allowing modifications and upgrades to the logic as we gain operational experience with the LINAC RF systems. [...]

Overview of the Spallation Neutron Source Linac Low-Level RF Control System
/ Champion, Mark ; Crofford, Mark ; Doolittle, Lawrence ; Kasemir, Kay-Uwe ; Ma, Hengjie ; Piller, Maurice ; Ratti, Alessandro
The design and production of the Spallation Neutron Source Linac Low-Level RF control system is complete, and installation will be finished in Spring 2005. The warm linac beam commissioning run in Fall 2004 was the most extensive test to date of the LLRF control system, with fourteen (of an eventual 96) systems operating simultaneously. [...]

Adaptive Feed Forward Beam Loading Compensation Experience at the Spallation Neutron Source Linac
/ Kasemir, Kay-Uwe ; Champion, Mark ; Crofford, Mark ; Ma, Hengjie
When initial beam studies at the Spallation Neutron Source (SNS) indicated a need for better compensation of the effects of beam loading, a succession of rapid-prototyping and experimentation lead to the development of a simple yet successful adaptive feed forward technique within a few weeks. We describe the process and first results..
