2.1 Auto Controller
The Auto Controller is designed to be installed in a standard 19 inch rack mount
cabinet and is shown in
fi
gures 2-1 and 2-2 along with the
fi
lament and dis-
charge power supplies. The controller communicates with the
fi
lament and dis-
charge power supplies through a RS-485 interface. A front panel switch allows
selection of either local or remote mode operation. The End Hall ion source can
be controlled from the front panels when local mode is selected. When remote
mode is selected, the End Hall ion source can be completely controlled via con-
nections to the rear panel. Alternately, programs selected from the front panel
can be enabled or disabled from the rear panel when remote mode is selected.
Sockets are installed on the rear panel for remote operation using either RS-
232 or an Analog interface.
The Auto Controller also interfaces with up to four mass
fl
ow controllers using
cables that connect to the rear panel. Four relay contacts are also available on
the rear panel if additional positive shut off valves are desired for the gas feed
system.
The Auto Controller is connected to the Filament Power Supply and the Dis-
charge Power supply through an RS 485 interface. When the RS-485 interface
is not connected the Auto Controller functions as a stand-alone power supply
and readout for four mass
fl
ow controllers.
2.2 Filament Power Supply
The Filament Power Supply is designed to be installed in a standard 19 inch
rack mount cabinet and is shown in
fi
gures 2-1 and 2-2 along with the Auto
Controller and Discharge Power Supply. The Filament Power Supply provides
voltage and current to the
fi
lament of the End-Hall ion source. This power sup-
ply communicates to the Auto Controller through a RS-485 interface.
Additional information can be found in the individual manual for the Filament
Power Supply.
2.3 Discharge Power Supply
The Discharge Power Supply is designed to be installed in a standard 19 inch
rack mount cabinet and is shown in
fi
gures 2-1 and 2-2 along with the Auto
Controller and Discharge Power Supply. The Discharge Power Supply pro-
vides voltage and current to the anode of the End-Hall ion source. This power
supply communicates to the Auto Controller through a RS-485 interface.
