Diamond Pixels / Bonn

• 2001/2002 UTS5 and CD91 single chip modules
• First diamond pixel assemblies
• Characterized in testbeam
• Poor bumping yield
• Not rad hard FrontEnd electronics chips
• 2004 CD109, new bumped UTS5
• Bumping improved
• Fully bumped pixel single chips (2880 pixels)
  with radiation hard chip
• Working in the lab
• Ready for testbeam this spring/summer
• Module practice piece to develop bumping of a
  large CVD module ? in processing at Fraunhofer
  IZM now
• Full ATLAS type module with 16 FE chips, 46000
  pixels planned for summer 2004. Testbeam planned
  for 8/2004 (schedule tight)
• Are ready for assembly of a single crystal
  diamond with an ATLAS-FE chip
• Charge collection measurements (TCT setup) with
  single channel Si, CdTe (and diamonds) presently
  carried out.
