9. Ion Source Parameters

The following table gives the default ion source settings for HPQ2-IP in its three
operating modes.

0.7mA or
0.39mA

70eV

7.0eV

-110V

HPQ2-IP HP

10.0eV

-130V

Emission Current in RGA Mode

On older instruments (those with serial numbers LM75-00298025 and below) the
emission current should be set to 0.70mA.

On newer instruments (those with serial numbers LM75-00298026 and greater) the

emission current should be set to 0.39mA.

This change results from changes to parts used in the ion source. An incorrect
emission current setting will result in a loss of sensitivity.
