Spark gap alternatives

[setec]

Hello. I'm researching cold currents and want to know opinions on semiconductor spark gap emulators, which fill following requirements:
- it blocks reverse currents
- it's able to work with HV (up to 30kv) impulses of relatively small currents (up to 5 mA)

Just because spark gaps are too noisy and causing much RF disturbances

What about triggered vacuum (gas) spark gaps? http://www.excelitas.com/Pages/Product/Spark-Gaps.aspx

Just an idea

spark plug via copper tubes or direct to ferrite cores ? just try it
