I think the suggestion Benedikt offered would be practicable. By the way, what is the FWHM (for a-Fe), 0.3 mm/s or even lower ?

Dear Benedikt and Ming,

In fact, the cryostat is not yet assembled. Th sens of my  question is to avoid the things that may result in high vibration.

I agree with Benedikt, rubber bellow is important, i will order one asap.

For the sandbox i think about an anti-vibration pad which could be easy for level adjustments.

so with that I hope to be below 0.3 mm/s

Best regards

We have obtained linewidth below 0.28 mm/s with this system when properly equilibrated. An important aspect is to really add the recommended weight on the table, about 250 kg if memory serves.

Good luck.

Thanks Raphaël,
