Wu, Yue (author), Liu, Xiuming (author), Li, Q. (author), Chen, Boxuan (author), Luo, Peng (author), Pronk, Arno (author), Mergny, Elke (author)By using inflatable moulds and then spraying cellulose-water mixture, one ice dome and two ice towers were built in Harbin in December 2016. During the whole process, form-finding of the inflatable moulds as well as the construction of these ice composite shell structures are very important for the final results.<br/>The mould for the ice dome...conference paper 2017

Liu, X.X. (author), Hayton, D.J. (author), Luo, Y.C. (author), Wei, L. (author), Vercruyssen, N. (author), Gao, J.R. (author), Groppi, C. (author)We report on realization of a 2 × 2 NbN hot electron bolometer (HEB) array receiver using multiple local oscillator (LO) beams that are obtained from a Fourier phase grating mirror. The grating splits a 1.4 THz single beam into four uniform sub-beams. Two 50mm lenses are applied to collimate each beam in order to achieve a spacing of 12mm...conference paper 2015

Luo, Y.C. (author), Liu, X.X. (author), Hayton, D.J. (author), Wei, L. (author), Gao, J.R. (author), Groppi, C. (author)A Fourier phase grating mirror will be applied to split a single, coherent terahertz source beam into multi-beams, which are spatially distributed as required for the local oscillator in an array receiver. We report on the simulation, design and fabrication of a Fourier phase grating at 1.25 THz for generating 2×2 beams, and the measurements at...conference paper 2015
