Presentation of Grygorii on 7.7.11
----------------------------------

Topic: Results and conclusions from the beam tests with JAI-BM141 camera.

Result of the discussion:

JAI-BM141 was installed at HIGH1.Scr3 for a while and got radiation 
damage. Background level increased, not uniformely. This was never seen at 
Prosilicas.

Grygorii will order 2 new cameras for further beam tests:
- 1st should be installed at a position parallel to Prosilica readout
   (2nd beamline) for direct comparison, proposal: HIGH1.Scr1
- 2nd should be installed at beamlet observation screen to compare the
   resolution of details, proposal: HIGH1.Scr4

In order to avoid fast radiation damage, the shielding should be improved.
Shielding at HIGH1.Scr3 should be checked, maybe non-uniforn distribution
of noise level after radiation exposion can be explained by the setup.

PS: After discussion with Galina, the easiest realisation of a parallel 
readout of Prosilica and JAI could be realized at PST.Scr1 (already 2 
beamlines available). We should discuss this option.
