Transient Buffer Boards (TBBs) are a part of I-LOFAR’s data computation hardware that allow signals from the sun, stars and other astrophysical objects to be recorded at one of the fastest time resolutions possible. They can show us how the sun and stars change at the nanosecond scale.
To do this, TBB data must be recorded to cluster of computers so that the large amount of data can be stored. The total amount of data all 12 of I-LOFAR’s TBBs can hold is 384 GB, which is only 5 seconds worth of observations if all 96 antennas are used. Not only does the cluster need to store large volumes of data, it has to write it fast enough so that it doesn’t get lost before more data comes in. The TBB data cluster in our control room in Birr writes data to a fast, 46 TB storage node.
Researchers in Trinity College Dublin are using the cluster to observe the fine structure of radio bursts from the sun at the highest time resolution that has ever been done before. This will allow them to solve unanswered questions about energy release and particle acceleration on the sun.
