Hi Daniel,

For that power supply and assuming a static gap, you will need a 
total of 10nf with a minimum of 14  1000V caps in a string.  Three 
strings will give you 10nf.  Figure on 42 caps.  I have some slightly 
used CDE 942C20S68K caps that are .068uf 2000V that I can give you, 
if you send me your address. With these, I would put 7 in a single 
string that would give you 9.7nf at 14000V.  If you want to spend 
your money, I would recommend a string of 10 0.1uf caps (CDE 
942C20P1K).  This would also give you 10nf at 20000V.  They would 
probably cost $1.80 US each (see mpaqelectronics.com for a quote). 
Also, put a 10Mohm 1/2 watt resister across each cap.
