Tile damage

During the HBA summator installation we discovered one tile lid that was partially fractured. We suspect this was from loading too many people on what may have already been a weak lid. Having found the crack, we removed it and tested to see where it would break and, if so, how. Here is the result.

A fractured tile is subjected to additional pressure.

Overall, the system has held up remarkable well. The LOFAR tiles turn out to survive the Arctic environment very well.
