Parts of CTA
It is the cold part of the Observatory. It is made of four main parts;
The cryostat keeps the instruments and the science payload of the spacecraft cold and enables its smooth functioning. It does so by venting helium vapors from a liquid helium tank, which can hold nearly 360 litres of helium. It houses the following instruments;
This telescope is designed to function in low temperatures. It is made of beryllium, which is a strong material, used to make infrared telescopes.
The outer shell is made of dust cover outer shield (cooled by helium vapor), thermal shields (which block radiation from space), and the solar panels. It surrounds the cryostat and the telescope.
The shell prevents heat reaching from the telescope and instruments by radiating it into space.
It is made of lightweight, aluminum honeycomb sandwich construction. The anti-sun side is painted black for efficient thermal radiation to cold space. The sun-side is shiny for efficient rejection of heat from the sun and solar panels.
Multiple Instrument Chamber
This part is contains three science instruments,
