  Due to the space radiation environment at L2, ESA's Euclid mission will be
subject to a large amount of highly energetic particles over its lifetime.
These particles can cause damage to the detectors by creating defects in the
silicon lattice. These defects degrade the returned image in several ways, one
example being a degradation of the Charge Transfer Efficiency, which appears as
readout trails in the image data. This can be problematic for the Euclid VIS
instrument, which aims to measure the shapes of galaxies to a very high degree
of accuracy. Using a special clocking technique called trap pumping, the single
defects in the CCDs can be detected and characterised. Being the first
instrument in space with this capability, it will provide novel insights into
the creation and evolution of radiation-induced defects and give input to the
radiation damage correction of the scientific data. We present the status of
the radiation damage of the Euclid VIS CCDs and how it has evolved over the
first year in space.
