  A total of 42 SLED Tuners are installed at the PAL-XFEL (4th generation light source) acceleration section. To adjust this, a person directly enters the Tunnels and adjusts them manually. When the SLED Tuners are equipped with a motor, it can be adjusted remotely and the intensity of the beam is also monitored while monitored while monitoring the output of the Klystron. In addition, by storing the tuning point according to the XFEL beam rate as the LVDT value, it is possible to control the SLED bar according to the beam rate changing in real time, which is helpful to provide stable beam. In order to remotely control this device, an additional motor, LVDT, and limit switch are attached. Each device is connected to the controller and can be operated and data remotely from the cab through the EPICS IOC and CSS.
