'''Saad Shaikh''', '''Simon Jolly'''

=== [[ELogs/SaadShaikh|Saad Shaikh]] ===
*Provided Simon with dimensions for 48-sheet stack holder to be used with Rev. B boards and CMOS sensor. Stack to contain 25 new clear sheets and 23 white sheets.
**Can do tests with shooting beam from both sides, to verify white sheets not performing well.
**Will see if sheets fit into existing holder, after fibre tests.
*Matt has modified 2 Rev. B boards to fix daisy-chaining issues. Now able to chain 3 boards together.
*Marko has provided editable schematics for FMC daughter boards. Forwarded this onto Matt.
*Sanded edges of 4 clear 2.86mm sheets that were too large to fit in stack holder.
**Some edges of clear sheets have significant machining marks – may need polishing/sanding before beam test.
**Will look into sanding down injection mould marks on 3mm sheets.
*Completed lab LED tests with clear sheets.
**Light levels in each sheet with the same fibre injecting light are reasonably consistent and significant cross-talk observed.
**Will test with white paper, black card and mylar foil.
