Saad Shaikh

• Conducted beam test at UCLH last week with rev. B and rev. C prototypes.
• Performed analysis and presented results in [this presentation]. Main conclusions:
  • Rev. C boards could benefit from additional grounding.
  • Clear sheets between 5-6 times brighter than white painted sheets.
  • White sheets produce poor results as in previous beam test – excellent fit results with clear sheets (after adjustment of WET of each sheet by approx. 0.1mm).
  • Rev. C fits inconsistent, likely due to poor alignment of sheets with photodiodes.
• Will travel to Miami at the end of the week to attend PTCOG and present results.
  • Will be on holiday after conference, returning to work on 13th July.
