Integrated PSD from cut frequency to 350 Hz of the linear vibration of the second crystal versus the linear vibration of the cryoline support mechanism. The numbers to the right of the traces are the division factors used to norm the cryo support vibration to the crystal vibration at 2 Hz. The crystal vibration data are offset 7 nm between the Bragg angles. All the shown data were obtained using a cryo pump speed of 15 Hz and a flow pressure of 5900 mbar. |
