Precision ion vacuum gage with logarithmic response
Technical Report
·
OSTI ID:5647955
A new ion vacuum gage controller has been developed for use with Bayard-Alpert gage tubes. The instrument employs a logarithmic-gain electrometer to cover up to 12 decades of pressure without the gain range changing. Instrument error and repeatability is +-1% of the pressure reading over a 9-decade pressure range with an ideal Bayard-Alpert gage tube. The instrument also offers selectable autoranging of fixed emission-current control. Futhermore, protection circuits and a computer interface are provided.
