We describe the performance of a 2k X 2k, 15 (mu) pixel, buried channel MPP-CCD (Loral FA2048) using different operating modes and the implementation of an anti-blooming clocking technique. The CCD is part of a camera system developed at Bonn University for astronomical wide field photometry and polarimetry. Besides two basic operating modes (partially and non-inverted mode) the multi pinned phase (MPP) design additionally allows a totally inverted mode providing the strongest reduction of dark current. The disadvantage is a low full well capacity of 120000 electrons/pixel which only depends on the small implanted potential offset. As an example for optimization by choosing adequate voltages we show how this original full well capacity can be raised almost by a factor of 2 without decreasing the quality of the read-out. Finally we discuss the physical understanding and technical implementation of anti-blooming and its future application in astronomical photometry. Using clocking rates up to 2 kHz we achieve a minimum anti-blooming efficiency of 400 electrons/sec/pixel/Hz and a low spurious charge generation further reduced by using ramps or intermediate steps in the anti-blooming clocking waveforms.
