Day 75

Morning
This morning was spent working on the beam pattern design. I got to work wiring a pot into the system so that I could see what adjusting on the fly would be like. It worked fairly well once I got a good scheme down for the wiring. The real interesting part was when I found the CH1 vs CH2 plots on the o-scope. I was only partially able to see the actual beam pattern because of the scan rate of the scope. I am hoping that they will look a little better when using the actual beam. I programmed in a few options and watched them go.

Afternoon
I began to document all of the different patterns in my document. I grabbed screenshots of them using the online parametric application. Dean needed help loading 11 so I spent a few minutes helping with that. It was interesting to watch the automated pump down on the furnace. They got down to about eight microns without a jet. It did take a while, but that's not too shabby. I stayed late to work on the document to ensure that it was close to done before weeks end.
