| Task | 10.6: LLRF at FLASH |
| Abstract | The LLRF (Low Level Radio Frequency) System has to control also the RF coupling with the FLASH accelerator cavities. It is done remotely by controlling RF Phase Shifters driven by step motors. It was necessary to design the multichannel stepper motors driver controlled via Ethernet. The driver is built on the basis of low-power CMOS 8-bit AVR RISC microcontroller and the MODBUS protocol. The 16 drivers integrated on a single PCB allow for controlling 16 RF (Radio Frequency) Phase Shifters for the proper adjustment of the waveguides to cavities coupling. |
