4.3.2 Gas Only Mode

When gas only mode is selected, the Auto Controller functions as a gas 

controller only. Independent control of the each of the four gas channels 

is possible. The description below outlines the use with one gas channel 

even though similar operation could be obtained using all the gas 

channels. Use the Operating Mode Select button to select the gas only 

mode. Selecting the Gas Only mode releases control of the Filament and 

Discharge Power supplies so that they can be operated independently. 

There is no feedback to maintain the discharge parameters. However, 

at any time during the operation in gas only mode, the setpoints can be 

acquired for operation later using the Auto Gas mode or the Manual Gas 

mode.

Note that if there is no communication link to either the Filament Power 

Supply or the Discharge Power Supply, the Auto Controller will only 

function in the gas only mode, which must be selected to clear the HLP 

7 message from the display. There will be no communication link if the 

power is switched off to either of the power supplies or if any RS-485 

cable connection on the rear panel is not connected to Auto Controller or 

either of the power supplies.

There are two modes of operation for the discharge: Constant Current 

Mode or Constant Voltage Mode. The Constant Current Mode allows for 

small variations in the discharge voltage while maintaining a constant 

current and is recommended when operating at 120 V and below. 

The Constant Voltage Mode will allow for small variations in discharge 

current and maintains a constant voltage. Constant Voltage Mode is 

recommended for operation above 120 V.

4.3.2.1 Constant Current Mode

The operating condition selected for this demonstration is with a 2.5A, 

120 V, discharge, which is Constant Current Mode operation. These 

conditions are based on a vacuum pump speed of 800 liters per second. 

Operating parameters for other pump speeds and gases can be found in 

the Ion Source Manual.

  Note that the operating range of the ion source may be limited by the 

vacuum facility pump speed or other process that take place while the 

ion source is running.

• Select Gas 1 using the white Gas Channel Select button on the Auto
