Boost converter?

I am making the rwilsfor07 boost converter, I already have the timer but the mosfet isn't working; I think that didn't work but I am not sure. Should I buy another one or buy a IGBT:

looks like we've got the same problem, but I'm much way further than yours, I already have my Boost converter and these last month and past few weeks its working. Its a two stage gun, now Its all dead I don't know why, the voltage doesn't reached more than 80V.... Now I will try to replaced and rebuild my entire system.
