Capacitor substitution for TEA nitrogen laser

Click For Summary
SUMMARY

This discussion centers on the substitution of strontium titanate ceramic capacitors rated at 50KVDC and 910pf for aluminum foil/plastic dielectric capacitors in a TEA nitrogen laser project. John proposes that using these ceramic capacitors may result in lower losses compared to commercial capacitors. The inquiry also includes a question about the capacitance equivalence between the foil/plastic capacitors and the ceramic options. The consensus indicates that while ceramic capacitors can be beneficial, their capacitance must match the original specifications for optimal performance.

My next project is to build a simple TEA nitrogen laser, as seen here: http://photonics.tfp.uni-karlsruhe.de/1/a-homemade-uv-laser.html

Would it be acceptable to substitute two strontium titanate ceramic caps, each rated 50KVDC @ 910pf, in place of the suggested aluminum foil / plastic dialectic plate caps?

My hypothesis would be if such materials were available than it would be beneficial for lower losses would be encountered with a commercial capacitor.

Let me know what you think about using a couple HV doorknob caps here.

Thanks,
John

What is the capacitance of the foil/plastic capacitors? Equivalent to your ceramics?
