4 INITIAL OPERATION
This initial operation is done locally from the front panel and serves to both demon-
strate and provide familiarization with operation. Make sure that the Auto controller
is switched to local mode. When using the gas only mode described below, the
fi
lament and discharge power supplies must also be in the local mode. For a more
complete description refer to the Operation section, Section 5. The description in
this section assumes that the installation sequence described in Section 3 of this
manual and Section 2 in the ion source manual has been carried out.
4.1 Gas
High-purity (99.999+%) argon, oxygen or nitrogen gas can be used in the ion
source. For other process gases, please contact Kaufman & Robinson, Inc.
The bottle, regulator and mass
fl
ow controller(s) should be installed and gas
lines evacuated as described in Section 2.4.3 of the Ion Source manual.
4.2 Power On
Switch on the front panel power switches to the Discharge Supply, Filament
Supply, and the Auto Controller. These switches are the rocker type switches
located on the far left of the three panels.
4.3 Operating Mode
There are three selectable operating modes for the Auto Controller. These
three modes include Auto Gas, Manual Gas, and Gas Only. All three modes
can be selected using the white Operating Mode button on the front panel of
the auto controller. Auto Gas and Manual Gas modes are available only when
the Auto Controller has established communication with the
fi
lament and dis-
charge power supplies.
4.3.1 Auto Gas Mode
When using Auto Gas mode, the gas is automatically adjusted to maintain
constant discharge current and voltage once the ion source is running.
Check to see if the green Auto Gas LED indicator above the Operating
Mode button is on. If it is not, then continue to press and release the Oper-
ating Mode button until the green Auto Gas LED is on.
