Notes

1. We went over the specification documents that have been posted so far on the wiki. Several suggestions were made to fill in missing parts
   • Top-level beam specification - add time resolution for tagging coincidences - R. Jones
   • Diamond specification - clarify the meaning of the rocking curve width for the entire crystal, increase the thickness tolerance to 5μr - G. Yang
   • Tagging spectrometer specification - Add tolerance information from the engineering design spec document - F. Klein

. Everyone knows the specification pages they are in charge of, and will work on them for next meeting.
