  1. for the 70 000 ADCs sensor chip, what is the ADC resolution, 8-bit or 10-bit??

      I think it was 10 bits.

  2. "he also introduced a very nice (and apparently very well received) idea of growing scintillators in cavities etched in silicon."

    it's not a new idea and is actually being manufactured already

    1. How about some details anon? Thx.

    2. structured scintillator was introduced long time ago. Philips has some technical papers on this subject. The method of Philips fills the deep trenches by scintillator grains. Needle-like CsI scintillator has the same effect to improve MTF.

      Not everything that I consider as being "very nice" needs to be new ;-)

    4. But in the way you write, guys can be mislead and consider this as NEW. This is not fair for the real inventors of such concept. Of course the nice things don't need to be new but need to be perfect and also need to give new inspiration for others. You are an opinion leader, so that is why this is particularly important.

    5. Speaking for myself, I thought the scintillator microstructure was new when I heard it in the talk. Not being that familiar with scintillators, one must rely on the speaker to give you the lay of the land. The speaker did not claim it was new, nor did he talk about prior art. So, maybe the particular structure was new, or maybe not.

      Anyway, if you want to help educate the community about prior art, it would be better if you gave specific citations or products we could check out rather than vague statements.

      On the other hand, using the right words makes a Google search productive, so thanks for "structured scintillator". I found:

      and
      US20040251420 (but did this ever issue as a patent??)

      just an example for you

  3. scint-x offers integratable modules
