Accelerator Project

Product & Reference

Mobiis supplied the control system and equipment (LLRF, SSA, Undulator) to the PAL-XFEL completed in 2016, and plans to supply prototypes and accelerator/experimental devices such as LLRF, BPM, SSA, Cryo modules, and ISOL to the heavy ion accelerator to be completed in 2021.

2856MHz LLRF Control System

Main Features
- Equipment for real-time measurement and correction of the distortion and deformation of resonance RF of accelerators
Details
- In order to precisely accelerate discharged particles to a desired speed, all accelerators have a structure of resonating the particles in high-energy RF for acceleration, and in this process, a disturbance in the voltage and phase of accelerated particles. It is a core equipment correcting the disturbance to maintain the performance of the accelerators.
- Currently, the LLRF of Mobiis has reached top quality RF voltage stability and phase stability, and product performance has been verified by the successful test run of the PAL-XFEL on June 29, 2016.

Solid State Amplifier

Main Features
- Equipment for amplifying the few watts of RF voltage produced by LLRF inside an accelerator to hundreds of watts through a precision amplifier
Details
- Our product requires a stable voltage and phase stability, rather than output power in contrast to general industrial amplifiers, and is a 900-watt amplifier operating in 2,856MHz pulse mode.
- The SSA supplied by Mobiis is remotely controlled from the LLRF, and requires precision control in order to maintain the voltage stability of 0.02% and phase stability of 0.03º.

XFEL Undulator Control System

Main Features
- Core equipment of the beam line unit producing synchrotron radiation by refracting accelerated electron clusters through an electromagnet
Details
- The Undulator Controller is a high precision control system controlling the Undulator, a large mechanical structure over 6 m, at a micron level

XFEL Undulator Control System

Main Features
- Equipment controlling all motors comprising an accelerator
Details
- A specialized equipment for accelerators with EPICS embedded inside, it uses Ethernet communication and 400MHz ARM920T CPU to quickly and stably control a maximum of 8 stepping motors
