This https://www.newark.com/vishay-gener...-5at/fast-recovery-diode-1a-1kv-do/dp/12M3636 would probably work for a diode. I'd put a little series resistance like <300 ohms or so. Diodes won;t fail if they are current limited. It also looks like you may want to capture the negative pulse.
The 1500 V ceramic caps that were used on old radios might be a good choice.
These https://www.toolplanet.com/product/...327&gpla=pla&gclid=CM2QqaGRibwCFUjNOgodkggApw might help too.
I have a lot of Fast Recovery Diodes "SHV-24" They are Rated at 24KV and 2 mA.
I can supply them For Free, Excluding Shipping Cost.
