A 1x4 focal plane array using 230 GHz SIS mixers

Abstract:

A new 1x4 focal plane array centered around 230 GHz is presented in this paper. The size of the array was limited to 4 pixels due to the space available in the test cryostat; however, we can expand the design in the future. On the front of the array block there are 4 waveguides flanges for the RF feed horns, while the local-oscillator signal enters through a separate waveguide on the side. The local-oscillator power is multiplexed using cascaded E-plane power dividers and then combined with the RF signals using directional couplers. Preliminary tests of the array block have now been completed. They show reasonable local-oscillator distribution and excellent RF signal isolation. Future work will involve testing the noise properties of the array block and improving the local-oscillator distribution.

The role of redundancy in blind signal estimation for multiple gravitational wave detectors

Abstract:

In this work, we extend our previous blind GW signal estimation method [H. Liu, J. Creswell, S. von Hausegger, A. D. Jackson and P. Naselsky, J. Cosmol. Astropart. Phys. 2 (2018) 013] to the case of multiple detectors and show that, with a full use of redundancy, it gives promising results, e.g. a faster decay of fluctuations than that expected from the central limit theorem. This method, whose design explicitly accounts for redundancy in multiple measurements, considerably improves the efficiency of signal extraction in a multi-detector network.
