Cold finger to quartz sensor.

Hello,
Looking to see if anyone has had experience cooling the quartz sensor in a vacuum? Looking to obtain liquid nitrogen temperatures eventually. Would a cold finger in contact with the clear area cause significant issues?

Thanks

  • Hi mswestph,
    this is Raffaele, from openQCm Team.

    I used cold fingers and QCMs in UHV during my Ph.D. thesis.
    I used this method in order to increase cleaning of the sensor and in order to avoid molecular degassing from the sensor. In my case I do not touched the active area, but placed the cold finger at a distance < 1mm from the QCM. In any case you will not damage the sensor, but you will observe a consistent frequency drift until T equilibrium.
    For further question, feel free to contact me again.
    Best
  • Excellent! This was the answer I was hoping for. Thank you for responding so quickly.
