the dark-shadowed flange ports are 300mm (12 inch) large.
antons wishlist:
-2xDiagonal (45 deg) VP for looking at alignment HeNe on sample
-Good light-tight shutters for keeping dark signal low on CCD
-Space for 90 degree mirror arrangement (LLNL imaging mode)
-Plenty of pumping for particle injection experiments
-Front end could have focussing optic, or
-Differential pumping stage on front end to allow chamber to run at higher pressure?
