What is the pre-TR tube for
Many Customers and Users of spectrometers ask this question. Therefore we give short justification of the need of use of the pre-transmit-receive tube of spark table of spectrometer SPAS-02.
The pre-transmit/receive tube of spectrometer has the following advantages:
- Provides with the maximal speed of current buildup in
dI/dtimpulse in comparison with any semiconductor analogs, that is the front of a digit pulse is most sharp that allows transmission of the energy of digit pulses to the analyzable sample with minimum losses and, as the result, improves generator efficiency.
- While maintaining constant conditions (temperature, pressure, humidity) in an auxiliary spark gap, it provides stable reproducibility of parameters of digit pulses that provides good convergence of parallel measurements.
- Reliability and simplicity of the design: is not susceptible to the destroying influence of currents (unlike semiconductor elements), the maintenance is not required.
- Protects the electric circuit of the generator from closing of circuit of the main spark-gap, what saves the resource of operation of protection devices.
