|Description:|| Over the past months, there has been intense work for the LOFAR4SW team in the different partner institutes. In particular, WP5: Hardware design - led by ASTRON and in collaboration with Paris Observatory, Nançay group – completed the production of the hardware components to build an HBA dual beam tile. These include: the HBA frontend, HBA beamformer boards, RF summation board and power distribution boards (the summation and power distribution boards are modifications to the current LOFAR boards). |
All the building blocks for a new HBA tile were assembled and verified in laboratory conditions. The tests performed on power, RF, control, show a good performance of the hardware and to be overall compliant with the requirements.
This is a major step towards the completion of the LOFAR4SW design, which ultimate goal is to deliver the full conceptual and technical design for creating a new leading-edge European research facility for space weather science. The new HBA tile will be capable of producing two beams, to allow parallel astronomy and space weather observations.
Currently, ¼ of a dual beam tile is assembled in the Dwingeloo test field and it’s producing spectra with 2 beams. In the coming weeks the full tile will be assembled, to study the behavior under real environmental conditions.
Credits go to the team at ASTRON: Mark Ruiter, Paulus Kruger, Jeroen Herrewijnen, Albert van Duin, Gerda Sikken and Nancay: Sangitana Rokotozafy Harison, Severin Barth, Bruno Da Silva, and Stephane Bosse.
The full LOFAR4SW design - that encompasses, science use cases, architecture, hardware, software, operations and governance model - will be assessed at the critical design review in a few weeks from now (21-23 September 2021).
LOFAR4SW is funded by the European Commission under grant agreement 777442 and will run until February 2022.
