The LEEA and HEEA Sensors
The LEEA Sensor has a larger collimator than the HEEA Sensor, to give a smaller geometric factor. LEEA can measure effectively in higher flux environments than HEEA.
HEEA has an extra connector on the Sensor Electronic Unit, through which data is supplied to the Correlator (part of the Digital Wave Processing experiment).
The Sensor Heads have additional radiation shielding compared to their ill-fated Cluster counterparts.
