Fiber Profiler Problems
Doug,Travis, Mark Barton
We ran into issues with the fiber profiler. We are unable to get the proper results and ended up with bogus numbers and graphs. Travis emailed Angus who had seen this similar problem before, but wasn't certain of the cause either. We ran 2 different programs and tested them with both new and old data sets yielding the same out come. Mark worked with us later in the day but found nothing obvious either. He will look at the programs, data base and spreadsheets tonight to continue to debugging. Rebooting the computer had its own problems as it took several tries to get it back online. We did manage to tweak the profiler mechanical alignment which allowed us to run continuous passes without having to stop and refocus several times.

In conclusion if Mark does not find an obvious problem we will wait until Jan to proceed. The puller is ready, just waiting for the profiler evaluations before the production run. The micrometer is fixed in place and alignment rechecked. I made up several more substrates and cleaned up some more clamp blocks and supports.
If Mark finds a fix we may hit it again tomorrow.
