JUpiter ICy moons Explorer (JUICE) is an ESA L class mission due for launch in 2022
as part of the agency’s Cosmic Vision program [1][2]. The primary science goal is
to explore and characterise Jupiter and several of its potentially habitable icy moons,
particularly Ganymede, Europa and Callisto.
The JANUS instrument is designated to be the scientific imager on-board the spacecraft
with a wavelength range between 400 nm and 1000 nm and consists of a catoptric telescope
coupled to a CMOS detector [3], specifically the CIS115 monolithic active pixel sensor
supplied by e2v technologies[3]. A CMOS sensor has been chosen due to a combination
of the high radiation tolerance required for all systems aboard the spacecraft and
its capability of operating with integration times as low as 1 ms, which is required
to prevent blur when imaging the moons at fast ground velocities since the camera
has no mechanical shutter. However, an important consideration of using CMOS in high
radiation environments is the generation of defects or defect clusters that result
in pixels exhibiting Random Telegraph Signal (RTS)[5].
A study of RTS effects in the CIS115 has been undertaken, and the method applied to
identify pixels in the array that display RTS behaviour is discussed and individual
RTS-exhibiting pixels are characterised. The changes observed in RTS behaviour following
irradiation of the CIS115 with protons is presented and the temperature dependence
of the RTS behaviour is studied. The implications on the camera design and imaging
requirements of the mission are examined. |
