Civil work and facilities progress report

Roughly, the OAJ is composed of two buildings for the JST/T250 and JAST/T80 telescopes, a residence, a control building, a general services plant, a monitor building and an aluminizing plant. Click here for a detailed technical description.

The aluminizing vacuum chamber and the cleaning unit arrive at OAJ after the final acceptance tests at the factory.

 
March
 
 

The OAJ aluminizing vacuum chamber has passed successfully the acceptance test at the factory. So it is going to be packaged and sent to the OAJ where it will arrive in early May.

Final assembly of the OAJ aluminizing vacuum chamber

After having passed successfully the preliminary and final design reviews, the manufacturing of the OAJ aluminizing vacuum chamber and the procurement of its subsystems started in spring 2015. The vacuum chamber is the system designed to realuminize the mirrors of the OAJ telescopes every time it is necessary. In November 2015 the chamber is fully assembled in factory, as it can be seen in the figure. The acceptance tests are expected to be conducted in December 2015 - January 2016.

The JAST/T80 building is isolated with galvanized steel panels to minimize the thermal inertia of the main concrete structure.

The monitor building consist of a semicilindrical enclosure made of steel with two openings which can open independently.

General installations and supplies are finalised inside the JAST/T80 building.

Operators working on the fine tuning of the monitor enclosure.

Underground tunnels connect all the buildings at the OAJ, both for human use and the optimal maintenance of the installations.
