Side view of the XAFCA endstation. V7 is a 150 µm beryllium window installed on a pneumatic gate valve to isolate the vacuum of the storage ring, front end and optical components from the endstation. V8 is a 15 µm polyimide window installed on a pneumatic gate valve to prevent the optical components from being polluted by the samples. ND is a 300 nm Ni foil detector to monitor the intensity of the X-rays with an energy below 3 keV. IC0 is an ion chamber to monitor the intensity of incident X-rays with an energy above 2.4 keV. The vacuum chamber is where samples are placed. A 270 l s−1 turbo pump is connected at the bottom of the vacuum chamber. A manipulator equipped with a cryostat and oven system is mounted on the top of the chamber to transfer and rotate samples along the z direction (vertical direction). The cryostat and oven system can provide a temperature range from 4.2 to 1000 K. |
