HBA testing

Like the Low-Band Array (LBA), the High-Band Array (HBA) also needs to be tested and the commissioning work finished. This means checking the response of the HBA elements and making sure that they respond correctly and give the correct signal output.


Caption 1 : In the event of a problem, an engineer needs to go out onto the array, find the unresponsive tile and repair it.



Caption 2 : Henri Meulman completes the work on one of the HBA tiles. It is possible to see the polystyrene skeleton of the open HBA tile.
