Operating Procedure for the 72-030 Neutralizer Control

IMPORTANT: In order to support a wider variety of system types, as of AugerScan version 3.12, the DR11 connection to the 72-030 Neutralizer Control has been changed to DR11-C, and the CSR for the controller has been changed to CSR 0. If you have been running you 72-030 with a previous version of AugerScan, you will need an additional DR11 cable, and will need to make changes to jumper settings in the 72-030 unit. If you have not recieved the cabling and/or instructions for this modification, please contact RBD Technical Support (tech@rbdenter.com)

To be able to access the neutralizer control, you must first select the 72-030 in the General Hardware Properties dialog box. The neutralizer control is only active for XPS and SIMS alignments, depth profiles, multiplexes and surveys. It will not be active for any AES acquisitions.

Select the Neutralizer Control command from the System menu to access the Neutralize Control dialog box.

Click the ON button to turn the neutralizer on. Set the emission and electron energy controls to the desired mA and %. Typically this is done while performing an alignment. The emission and electron energy controls are adjusted until the peak that is observed during the alignment is in the correct eV or Mass position. An emission value of 18 mA to 23 mA and an electron energy value of 10% to 30% are typical.

In each acquisition type, there is the option to turn the neutralizer on during the acquisition. If the Neutralizer On box is checked, then the neutralizer will be turned on to the previous settings when the acquisition begins, and will turn off when the acquisition is finished.

It is recommended that the neutralizer be turned Off when not in use.

Refer to the PHI manual for optics resistance measurements and filament replacement procedure if the neutralizer does not perform properly. RBD Enterprises provides rebuilds for the filaments in this neutralizer.
