Subject: temp sensor 2 of RCAV is too noisy 

temp sensor number 2 of the reference cavity shows much more (horrible) noise compared to the other ones (2K pkpk).

broken, oscillating?

Will check this tomorrow.

 

- personal notes -

things to do: change limit of both heaters to match new situation. much less power required and messing up things causes both cavities to heat up too much (50 C)...
