A Gamma Ray Imager
UNI Ferrara/LSS (Lab for Sensors and Semiconductors): development techniques for broad energy band crystal production (ondulated crystals).
CNR/IMEM- Parma: techniques development for production of new mosaic crystals.
Difference between measured image and Monte Carlo image in the case of a perfect assembling of the crystals in the lens
Counts (arbitrary units)
Deflection by 100 rad of a 200 m thick Si plate
Deposition of tensile layers on a substrate is a method to bend a sample
Deposition at high temperature
Cooling at room temperature
Internal stress is generated according to Stoney’s equation
NIM B 234(2005)40
Layout of an undulator
Strain is more homogeneous than with the indentations and does not deteriorate the crystal
