X-End temperature sensors

K. Venkateswara

Attached plot shows the various temperature sensors at EX. The thermistor temperature sensors temporari;y use the PEM tiltmeter channels as described in 14825. The two left plots show the thermistors and the top right plot shows the PEM temperature sensors. The very low frequency position of the beam-balance is also a sensitive thermometer as seen in the lower right plot.

There seems to be some oscillation in the temperature control loop for the VEA seen in the last 1-2 days. May need some tuning.
