Raith is being qualified... Thread: Required Limits of keV operation through 6APRIL2004 on RAITH 150

Please Everyone:

We would like to operate the system in a range between  10 - 15 KeV 
and/or at 20100 to 2100 kV only. NOT 20 kV or higher than 21 kV.

 When  I return from Germany and with LEO field service we will perform 
further testing on the column. 

Things are in good order and tomorrow I plan to put the system back into 
green light mode as more measurements and imaging is completed

Stitching Mean + 3 sigma was 19 nm.

Thanks to everyone for your support during this challenging period,
