Abstract

Experimental investigations and numerical simulation of the thermal control system performances as well as local electric heaters control parameters are discussed. The possibility of thermal stabilization of light-weight segment for fused silica mirror is investigated. Heating and cooling times for the structural mirror are calculated. Temperature fluctuations are modelled for the mirror surface by means of a lamp heat radiator. Capabilities of the Thermo- Optical Compensation System analyzed.
