Amplification
The ratio of output magnitude to input magnitude in a device intended to produce an
output that is an enlarged reproduction of its input. See also: Intermediate Power
Amplifier, Solid State Amplifier.
Amplification Factor
The voltage gain of an amplifier with no load on the output. See also: Intermediate
Power Amplifier, Solid State Amplifier.
Amplitude Distortion
Distortion that is present in an amplifier when the amplitude of the output signal fails
to follow exactly any increase or decrease in the amplitude of the input signal. See
also: Intermediate Power Amplifier, Solid State Amplifier.
Analog Digital Converter (ADC)
An electronic device used in the PTS to convert analog to digital signals.
Anode
A positive electrode (such as a primary or secondary electric cell) toward which the
negative ions are drawn. See also: Anode Power Supply.
Anode Power Supply
Located in the Power Supply Room (PSR). A component of the radio frequency
system that provides power to the final power amplifier. See also: Intermediate
Power Amplifier, Solid State Amplifier, Final Power Amplifier.
Area Emergency Stop Button
Located throughout the facility. Switches off electrical power to most equipment in
the area where the button is located. See also: Global Emergency Stop Button, Local
Emergency Stop Button.
Beam Current Regulation Electronic Unit (BCREU)
An electronic device that interfaces with the ion source. See also: Electronic Unit.
Beam Line Control Unit (BLCU)
A Programmable Logic Controller (PLC) that is the main control unit of the Beam
Supply System. The BLCU is basically responsible for control of the following
devices: power supplies of the beam line (and extraction) magnets, scanning magnet
power supplies, switching cabinets for the switched beam line power supplies,
vacuum valves and controller, primary and turbo pumps, insertable devices (Beam
Profiles Monitors, Beam Stops, RA Neutron Shutter), etc.
