Cleaning the windows

I removed the windows of the long tube, and found some small black grains on the inside surface. I carefully cleaned the window and reinstalled them immediately. After that I passivted the both tube for about one and half hours, the long and short tubes emitted red light. Finally I measured energy of the TWIN excimer with 45 mJ, and the beam pattern looked better than before.
