you.

Grab you session back if you are available.

Hi James,

 

I was using the Raith this morning. I usually use 20KV and the 7.5um aperture for writing. Somehow, I didn’t find the 7.5um aperture when I adjusted the gun alignment, and I didn’t find the 10um aperture, either. Also, I didn’t see any image when I used the 7.5um aperture and got an extremely dim image when using the 10um aperture. I cancelled my session. Could you tell me how I could try to fix this problem next time if I meet this again? Thank you.

 

Best regards,
