• Painted 4 scintillator sheet pairs:
  • Sheets 48 & 23 with primer – one layer to glue pair.
  • Sheets 54 & 1 with appliance – one layer to glue pair.
  • Sheets 52 & 11 with appliance and then primer to glue pair – 10-15 mins for appliance layer to dry.
  • Sheets 53 & 2 with appliance and then primer to glue pair – 30-40 mins for appliance layer to dry.
• Neither combination gives acceptable results: lots of gaps in paint layer due to either inconsistencies in sheet thickness, placement misalignment or paint reaction.
  • Placement of sheets when glueing is difficult: not much room to adjust once placed as this ruins paint layer.
