abstract = {ULTRASAT (ULtraviolet TRansient Astronomy SATellite) is a
wide-angle space telescope that will perform deep
time-resolved surveys in the near-ultraviolet spectrum.
ULTRASAT is a space mission led by the Weizmann Institute of
Science and the Israel Space Agency and is planned for
launch in 2025. The camera implements backside-illuminated,
stitched pixel sensors. The pixel has a dual-conversion-gain
4T architecture, with a pitch of 9.5 μm and is produced in
a 180nm process by Tower Semiconductor. Before the final
sensor was available for testing, test sensors provided by
Tower were used to gain first insights into the pixel’s
radiation tolerance. One of the main contributions to sensor
degradation due to radiation for the ULTRASAT mission is
Total Ionizing Dose (TID). TID measurements on the test
sensors have been performed with a Co-60 gamma source at
Helmholz Zentrum Berlin and CC-60 facility at CERN and
preliminary results are presented.},
