Questions Limitations of what is available
now? Dominated by MCT - few manufacturers Photov
oltaic only to 12 um - but in big arrays PC -
good to 20 um but would be very for large
format - if possible
3
Questions What could be available now? Blocked
Impurity Band - 2-100 um (but 4K, maybe slow
too) Custom MCT cheap off the shelf RT
microbolometers/pyroelectric
4
Questions What is not currently addressed? High
speed array readout capability Very high
response time (ps) (including for FEL
diagnostics) Near Background Limited performance
across wider range

• Questions
• What might be available in in the longer term?
• New readout integrated circuits - new approaches.
  Do not currentlymatch our requirements.
• Superconducting detectors - interesting but lots
  of questions
• Superconducting SPC beyond 3um
• Array construction (1D and 2D)
• Is 3 ps response really achievable
• Dynamic range?

6

• Questions
• Who is based placed to develop these?
• Custom large MCT - restricted largely to military
  suppliers or Qinetiq
• Custom PC MCT - few other suppliers - expensive
  hand made
• Superconducting - requires international
  industrial-academic collaborations
• CCLRC capabilities for readout

7

• Questions
• What new systems would have most impact?
• Longer wavelength response big arrays (beyond 12
  um)
• Faster readout big arrays (maybe 10x faster to
  start)

• Questions
• Who might fund this?
• EU? Facility Development? INTAS? Collaboration
  with instrument manufacturers? Joint projects
  with other synchrotron sources?
• But could be serious money...

But... Should determine more clearly what are
the science drivers in this area. This will
determine pixel sizes, speeds, response times
wavelength range...
