This page provides documentation for an inexpensive CCD camera being developed to read out dark matter detectors. It may also find use for other applications (i.e. neutron detectors).

Please also see new page EMCCD_Ideas about a possible EMCCD camera.

Design Notes

One frame is 1600x1200 or 1.9Mpixel. If we digitize with a 12 bit ADC, well need two bytes per pixel or 3.84MB. (2Mx8 or 1Mx16)

ISSI makes some reasonable-looking synchronous SRAMS which could be used if we go with a custom board.

Note that we expect to run this prototype at room temperature. There is also a  diagram from the 2005 version.

Xilinx Boards

 Nexsys2 board

  • ++ 256 color VGA
  • ++ USB readout supported for data transfers
  • ++ Micron PSDRAM (can be used in asynchronous mode)
  • ++ only $99
  • -- USB software support is windows-only, no source code, an unknown quantity
  • -- Brand new product; no user manual (yet!)
  •  Spartan 3E  starter kit
    • ++ We have them
    • ++ SiTCP support
    • -- VGA port is only 8 colors
    • -- DDR SDRAM (hard to use without microblaze)
    • -- USB port not supported for data transfers

 XEM3005 board

  • ++ Linux software support
  • -- no VGA connector
