Hello all,
I recently cleaned my ion source (5977A - Extractor source) and installed two brand new filaments. On my tune report, the EM volts for both filaments are between 1950 and 2005; the gain factor is only 0.389; water and nitrogen are below 4%. Does this seem to indicate that I should replace my EM horn, or is it more likely that there is contamination of some kind? Or something else? The EM volts seem awfully high for two brand new filaments.
Thank you!
