Tianlai Analysis Teleconference

Wednesday 17 Aug 2022, 08:00 → 10:00 US/Central

Peter Timbie, Peter Timbie (UW-Madison)

Minutes

 

1) Beam covariance mattrix, FRB localization - Furen Deng presented simulation for Tianlai dish array.  Planning to do with actual dish data.  slides below?

2) Status of "Local Effects" paper .  Peter Timbie.  See attached current draft below.  Seems to be general agreement that we should separate cross-talk from ground pickup discussion and write two different papers which reference each other.   Albert asked about whether there's a feature in the delay spectrum at the right delay.  Fengquan is working on measuring the noise of the Tianlai LNA's.   Will also try to measure S parameters for some of the dish pairs:  2V-8V, 2V-10V, 2V-15V.

3) Status of Tianlai/BAORadio Collaboration Meeting, 21 cm Cosmology Workshop - Peter Timbie.  See linked Indico pages below.  The local meeting being organized for next week in Xinjiang has been postponed by a month because of COVID.
