Revision of the Westerbork Synthesis Radio Telescope 2013-2016
| Submitter: | Jan-Pieter de Reijer |
| Description: | Since 1996 the WSRT has successfully operated with the Multi Frequency Front End antenna and the IVC, DZB, TADU and PuMa back end electronics. In order to be fully prepared for the coming APERTIF era, all telescopes are completely overhauled. The telescope steering control system ( frequency converters, cables, encoders and software) has been redesigned. All telescopes now have 144 glasfibers to the main building, for data and control. The telescopes are cleaned and painted. Bolts damaged by rust were replaced. In the 12 APERTIF telescopes, 128 coax cables were installed, to the focus box. In the 2 remaining telescopes, 4 new coax cables were installed, for VLBI and test measurements with the MFFE receiver. The APERTIF electronics (beamformer) are housed in a shielded container, under the telescope. An extra roof protects the container from extensive sun load. Bearings were replaced in all declination- and hourangle gearboxes. The power distribution (3kV transformers and cables) has been updated to meet the actual regulations. We are confident that the WSRT again faces a new successful future. |
