Hi Debbie,

If you are free I am going to be working on the S4160 after ~3:30 PM today.

I would like to review with you the column set up and make sure you 
obtain the brightness you need to obtain your image or measurements.

Likely you came onto the system when  it was set up for imaging very 
tiny structures using the smallest apertures and encountered less beam 
current than you are accustomed to.

If you are not here or available this afternoon please stop by Monday 
afternoon when I will likely also be working on the tool with the 
Hitachi Field service experts whom are here doing repairs to EBEAM.

Thank you,

James Conway
