CT 6001 Cyanogen Plasma Glow System provides
a means of measurement of gaseous content and coating density
in most types of incandescent lamps in the laboratory and
on-line quality control conditions.
Operation of the CT 6001 is based on the
latest achievements in microprocessor, power conversion
and radio frequency (RF) electronics. The combination of
well proven classical RF with the power of modern data processing
and calculation created this unique-in-its-class instrument.
Its simplicity, friendly menu, use of popular
computer spread sheet software and high reliability of presented
data makes this "one of a kind" system available.
CT 6001A Cyanogen Afterglow System is responsible
for Plasma Decay measurements from moment of excitation
to final decision for the lamp under test.
The CT 6001 bases the good/bad lamp decision
on two Reject Algorithms:
- integration of the signal from the photomultiplier
during the plasma decay and,
- time measurements of plasma decay.
The Decay Integration Method
will sample the signal level from the photomultiplier when
the excitation is shut off to the "end" of decay with a
560 ·s sampling rate and by adding all of them in graphical
integration. The good/bad lamp decision is based on decay
area. If the decay area exceeds the preset value, the lamp
will be judged good.
The Time Method will
sample the signal level from the photomultiplier when the
excitation is shut off and then measure the time for the
photomultiplier signal level to decay to a preset level,
representing a percentage of the initial sample. If the
decay period exceeds a preset time, the lamp will be judged
good.
The CT 6001 has capability to upload data to a PC compatible
computer to graphically display the plasma excitation and
decay characteristics.
The two parameters that affect the reliable readings of
Plasma Afterglow Decay are the energy from the power oscillator
AG 0201 HV-OS and the outputs from Photo Multiplier CT 6002.
The Front Panel of CT 6001 provides the controls to manually
adjust High RF Voltage from AG0201 HV-OS oscillator and
High DC Voltage from internal Power Supply to the Photo
Multiplier Assembly. The intent was to use this as a setup
tool. This feature could be used as a production analysis
tool when setting for Quality Control. It could be also
used as laboratory instrument to evaluate new products or
concepts.
