Abstract
The GTC dome is a rotary, pre-raised, hemispherical structure with an external radius of 17528 mm. The dome design objectives pursued were as follows: (1) To reduce total weight to a minimum in order to diminish thermal inertia and the power required by dome and observation shutter drive mechanisms. (2) To obtain a rigid structure with high eigenfrequencies to reduce noise reaching the telescope. (3) To ensure good internal ventilation; to this end there are 16 ventilation doors and an air chamber inside the dome wall, and heat insulation on the inside surface of the wall.
