TL;DR: In this paper, the blue print of the FAST PAF development and corresponding scientific goals are introduced, as well as the progress has been made in these PAFs, and a detailed description of the progress can be found.

TL;DR: The Square Kilometer Array (SKA) as discussed by the authors is the world's largest synthesis radio telescope, which will address many fundamental questions about our universe, and many countries including China are involved into the key technology development, such as antenna prototyping and Phased Array Feed.

TL;DR: In this paper, a single-piece panel reflector made of carbon fiber reinforced polymer (CFRP) was adopted to make DVA-C a complete system for experiments on antenna performance test and preliminary observations.

TL;DR: In this paper, the authors analyzed the fitting confidence intervals of the solar wind velocity, and presented some preliminary results achieved using FAST, which points to the current FAST system being highly capable of carrying out observations of interplanetary scintillation.

TL;DR: In this paper, a fast demodulation method is proposed to sense the acoustic and temperature with EFPI-FBG hybrid optical microphone accurately based on spectrum analysis technology, which can detect the change of the F-P cavity's length and the drift of the FBG's central wavelength with a high speed and accuracy.
