TARLA Design

The TARLA accelerator is a Free Electron LASER facility producing laser light in a range of 3-250 um using a 15-40 MeV electron beam. TARLA is designed for nuclear structure and gamma radiation studies, as well as direct electron beam experiments for material and detector research.
The acceleration system of TARLA consists out of 1 normal-conducting (NC) RF-Gun, 2 NC buncher cavities and 4 super-conducting (SC) Tesla-Type cavities housed in 2 cryomodules.

LLRF control system for TARLA

The low level radio frequency (LLRF) control system for the TARLA accelerator is based on MTCA.4. The system regulates the RF field amplitude and phase of accelerating structures to user specified operating points in presence of disturbances, e.g. beam loading or resonance frequency changes.
The RF field control system allows to tune and to regulate the resonance frequencies of each cavity by means of mechanical tuners for slow perturbations and in case of SC cavities by fast piezo tuners.
The software is prepared for an easy integration into TARLA EPICS control system environment. The system is highly flexible and extendable to include advanced control functionalities.

The control system is designed and commissioned in cooperation with the MicroTCA Technology Lab at DESY.
