Left: To install receiver cartridges into a dewar, the dewar is mounted on a “tilt table” to give sufficient space for the installation of the cartridge. In the picture, the dewar is tilted by 90˚. Right: Dewar of the ALMA receiver. 10 receiver cartridges

In addition to preparing for scientific projects for ALMA, ASIAA will also contribute to the construction of the array and associated engineering projects. Under collaboration with local industries in Taiwan, ASIAA will establish the front-end integration center (FEIC) for the Atacama Compact Array. All the front-end subsystems for ACA will be assembled and evaluated at FEIC in Taiwan. In addition, ASIAA has been working on the highest frequency (950 GHz) receiver band with ALMA-J, and is also participating in the development of ALMA software in Germany and the US.
