Medipix 3’s unique properties for XRD.
• Extremely stable.
• Extremely reliable
• High count rate linearity per mm2 => Extreme count rate linearity per strip.
• Small pixel size.
• With silicon sensor optimal for use with 8 keV radiation.
• No maintenance needed.
• Very low noise

Some observations
• Collaboration with the Medipix consortium has always been open, pleasant and
constructive.
• We learned a lot from the Medipix collaboration and have very much appreciated that we
have been involved in the development and testing of devices.
• On site (in Almelo) support by the CERN team has speeded up the development at
Panalytical.
• The collaboration with Nikhef has been and still is very strong: several production steps
are still performed at Nikhef.
• We like to believe that our involvement has made the Medipix 3 a very successful chip in
terms of performance and stability
