  • Several rebuilds with improvements to grounding and field cage attachment
  • Still no light frown
  • HOWEVER!
  • DSC_3975.jpg
  • Lens on the CCD was stopped down to f/5.6, cutting roughly 90% of its area
  • Opened lens wide to f/1.8
  • I now see light!
  • Took a series of 60 images, 2 second exposure and combined them to show how the source glows
  • All are 2x2 binning
  • A540_C100_E2_S60.gif
  • Z axis has been compressed to show the spread of light... This is at very low dift field.

  • Strange how it seems the glow reduces with increased drift field... early days yet
  • Cross pattern is likely the alighment of the amplification region mesh.

  • Image of the Mesh... Patterns are in same directions as the mesh x and y

  • Finally some light!
  • Need to move the source... probably use a lower intensity source.

HPTPC

  • T111 appears complete, minor cosmetic things such as, cleaning the floor, some minor water work, looks like a lab!
  • Need to layout where things should go on the floor to organise space, power cables etc.
