Saad Shaikh

• 25 new 2.86mm sheets labelled and measured.
  • 3 sheets slightly too large for holder, will need sanding.
  • Will optimise stack with 48 sheets (25 clear, 23 white) and find required depth for stack holder.
• Cut 5 10cmx10cm Mylar foil sheets for lab LED tests. Will begin tests from tomorrow.
• Implemented high-resolution PDD and PDL curves in simulation
  • Observe stepping in dose-depth profile correlating with sheet widths. Limiting max step size may fix this.
  • Observe diverging light output at sheet boundaries. Will need to track photons to investigate.
• Matt Warren
• Simon has spoken to Andy Poynter about beam tests: possibility to do 2 beam tests before end of September.
