Air temperature stabilization in the thermally isolated optical laboratory

For the studies and calibration of optoelectronic components of the high-precision laser based metrology systems the large volume (50 m³) thermoisolated lab based on seismic isolated concrete block is created. The inside lab volume temperature stabilization for the daily observation at 16.5°C is ±0.05°C with ±0.015°C temperature difference between maximal space separated points. This work was initiated by the needs of high-precision alignment of accelerator components of the CLIC, ILC-type colliders.
