Some misc. notes from Do Young Noh's (DYN) experiment time - March 14--21, 2006
- DYN JJ slits should work with bipolar and microstepper drives but found only fully reliable behavior with bipolar drives (SPD-6B's)
- Use microns as slit units as don't have enough resolution in spec otherwise with mm units
- Did not save all motor settings for the DYN JJ slits, but recall the following:
(1/2 step mode)
48 steps/rev,
gap/aperture = 39.024 microns/revolution
center = 15.485 microns/revolution
- ti4 table had to be lowered by approx. 5 mm
- Used Newport crossed x-z stage (that we use for Lois Pollack) to support addition beam mask at end of flight path
