A small step for the telescopes, a giant leap for the e-EVN

Submitter: Zsolt Paragi
Description: The e-EVN run on 21-22 June 2016 was special for two reasons. This was the first time that a subset of the telescopes streamed data real-time at 2 Gbit/s in an e-VLBI experiment. The six stations that have already upgraded their MkV firmware to do this were Effelsberg, Hartebeesthoek, Medicina, Noto, Onsala and Yebes. Three other stations joined at the usual 1 Gbit/s rate.

In the test part of the run we also celebrated real-time e-VLBI fringes for two Russian KVAZAR network telescopes: Badary and Zelenchukskaya (for now at 512 Mbit/s). During this test time, nearly 17 Gbit/s data reached JIVE. The possibility to increase the data rate to 2 Gbit/s, and to add these two telescopes to the real-time e-VLBI array in the near future will have a great impact on the sensitivity and imaging capabilities of the e-EVN.

The image shows fringes for all the e-EVN baselines with the reference telescope Badary, and the team working at the JIVE Correlator Operations room.
