We had a very good day!

We will installed the upper quartz and dome, confirmed correct wafer 
placement in process chamber and pumped down system.

System is now baking out.  I will come in on Friday to etch the chamber, 
get temperature readings and run silicon depositions.

We will update on you all on Friday.
