Topics

• Development of our X-ray CCDs
• MAXI-SSC for all sky survey, Hayabusa for small
  asteroid study
• Pursue a large format CREST-CCD, NeXT1, NeXT2
• Thick depletion layer Pch CCD instead of
  conventional Nch
• Development of P-channel CCDs for NeXT (Ozawa,
  Poster 8)
• Thin absorption feature BI CCD then NeXT_SXI
• Development of fully depleted and BI CCD for NeXT
  (Takagi, Poster 9)
• Soft X-ray Imager, SXI, for the NeXT mission
  (NeXT team, Poster 5)
• High efficiency at high energy SDCCD quite a
  novel concept
• Hi resolution wide band photon-counting SDCCD
  (Miyata, Poster 10)
• Balloon experiment, Sumit, and 2k x 4k CCD,
• Working temperature of the CCD CCD degradation
• Low power and high speed ASIC M01 MD01

Summary

• Position resolution biggest advantage of the
  CCD
• We can have a sub-pixel resolution
• Effective area one inch square chip is well
  established
• Large format reduces yield ? Buttable device
• Wide energy range SDCCD (BI) can cover 0.1100
  keV
• Low energy ? BI chips covers down to 0.1 keV
• High energy ? Thick depletion layer (Pch)
• ? SD CCD (up to 100 keV)
• Time resolution biggest disadvantage of the CCD
• Multiple readout nodes ? ASIC (100 times faster?)
• High time resolution can avoid pileup and may
  eliminate the OBF
• Radiation damage we need a beam test
• Novel cooling system is required for NeXT (-90C
  is not enough)
