etc). - This GUI is written and 90 tested,
unfinished stages remain (Disperser Server,
Grating tilts, detect. focus) User Level
Software - Two GUIs at this level - Instr.
control interface (select a grating, etc.) - 75
done - Graphical Instr. Status Display - 50 done

Slit Masks Laser mask cutting system -
high quality masks delivered to SBS for
testing - some laser tuning issues remain -
still debugging RS-274 (G-code) generation -
syntax - storage of used masks? - order of
large stock of mask blanks? - mask blanks
approx. 100 each
