5 Dish Antenna Down Select In Nov 2016, the MTM/CETC54 panelized aluminum space-frame antenna concept was chosen over the NRC composite antenna.

10 Phased Array Feeds In the Mar 2015 Re-Baselining, the SKA1-Survey telescope and the Phased Array Feeds (PAFs) were deleted. PAF development was recommended to continue under an advanced instrumentation program (AIP), to make PAFs available for use on SKA-Mid during SKA2. Preliminary meetings have been held between NRC, CSIRO, and Astron to discuss the formation of a PAF AIP consortium, and this will get formalized in the coming months. NRC will continue its current developments L-band (SKA Band 2) room temperature Vivaldi C-band (SKA Band4) cryogenic Vivaldi. NRC has future plans for cryogenic PAFs at higher frequencies.
11 Phased Array Feeds The primary scientific driver for feed arrays is survey speed, for which the figure-of-merit may be expressed as: SSFoM nbeamωbeam BW η / Tsys 2 Where nbeamωbeam is the total sky area covered by the feed array, where BW is the effective bandwidth, η is the effective antenna efficiency, and Tsys is the system temperature. A phased array feed is scientifically interesting if it is not too costly, and if the SSFoM is significantly higher than that of a state-of-the-art single pixel feed, eg; the SKA Baseline design V1 had this ratio at x16 for Survey Band2 PAF relative to Mid Band2 SPF.
12 L-band room temperature Vivaldi PAF Tsys hot/cold load test results below would translate into Tsys~28K on-sky. EMSS SPF results were Tsys~14k on-sky
13 CryoPAF4 Cryogenic Vivaldi PAF History 2014: DISH consortium, Band : NRC project, new frequency Goals Phased array feed receiver Frequency: GHz Tsys~19K noise temperature, cryogenically cooled antennas and LNAs 96 active elements Dual linear polarization
