Low level Radio Frequency (LLRF)
What is LLRF doing?
Control and maintain the specified phase and amplitude stability of accelerating field in RF cavity during beam traveling. Also maintain the filling stage of the RF pulse.
The stability requirement varies in different accelerators, determined by specific application. e.g. XFEL:0.01% and 0.01° ; SARAF: 0.1% and 0.1° ; SNS: 0.5% and 0.5° ; JPARC: 1% and 1°.
Why need LLRF?
