Experimental Results on PSd
PSD sensors have been integrated in two ASSE mini modules and several experimental test sessions have been
performed to check the tracking accuracy (see Figure 57). The result of a typical test performed on a full day is
reported herebelow.
The I-V curve of one module and the misalignment errors measured by both PSD sensors have been logged with
a sample time of 30s. Only one PSD sensor has been used for the closed loop tracker control. During the test-day the
misalignments between the planes of the two PSDs has been below 0.04°.
