Title:
SCI-X11
Large Format Detector Read-Out - Additional work
Within the original contract a basic development for a read-out for future high resolution imaging spectrometers is undertaken.
The study will focus on the electronics required to readout future high resolution imaging spectrometers. It will result in a
complete instrument capable of delivering packaged data containing spectral and imaging outputs from detector arrays of up
to 10,000 pixels. The key issues to be addressed are the design of the full readout chain, power requirements, noise
performance, thermal requirements, and the rate and speed limitations.
More in detail, a read-out electronics for large array detectors shall be designed, fabricated and tested. The design shall be
scalable, radiation tolerant and highly integrated. In order to reduce the required interface circuitry to an absolute minimum,
the ASIC shall include:
1) ultra-low noise preamplifiers for each individual detector pixel, to achieve detector statistical noise limits
2) programmable filter stages for each pixel
3) event detection circuitry, with internally programmable threshold settings
4) analog-to-digital converters
5) event prioritization circuitry
6) digital glue logic.
In addition to the basic development summarised above, it is now proposed to place a CCN to cover additional testing and
validation issues. During the development of the ASIC, it was realized that the circuit could not be sufficiently tested without
any detector connected to it. Therefore, in order to validate the full functionality, it is required to bump-bond a 2-D detector
array to the ASIC and test this assembly under X-ray radiation. In addition, and for the specific need for BepiColombo, the
ASIC needs to be validated under gamma and proton irradiation. These radiation tests will also help to understand the basic
limitations of the particular foundry and CMOS process, which is used not only for this development but also by several other
institutes / companies intending to design ASIC for BepiColombo and Solar Orbiter.
Deliverables:
Set of ASIC wafers and ASIC + Detector assemblies as well as the full design databases.
