Jeg,

well yes, almost, i gate straight to the UCC27511 MOSFET driver before the IRFP260.
I know thats 2 drivers behind each other and it will work also without the UCC27511, but that was kind of hard to setup on short notice.

Thanks Itsu, I will need some more details on your transformer but I will ask you again when I
ll be there.

Itsu.

I'd like to ask you the range of the pulse's width. I see at the above screenshot 11 ns. Is that the lower width?

In addition what Scotcy diode do you use at the drain of your mosfets?

And about this blue toroid that you used for the output transformer. Where do you find this? Is it from scrap or it needs to have specific permeability?

Thanks

Hi jeg,

i was afraid you would come up with those questions 

The pulse width of 11ns is given/calculated by the scope, i think the standard is to use the width at ½ amplitude (FWHM; Full width at half maximum,
https://en.wikipedia.org/wiki/Full_width_at_half_maximum), but it could depend on the scope.
Perhaps some experts could drop in here.


The schottky diode i have presently in is a D08G60C (http://www.datasheetlib.com/datasheet/383674/d08g60c_infineon-technologies.html)
But the new nano-pulser i am building will be using a D12G60C which is more easily to cool on a heatsink and available in my partsbox.

The blue toroid was one i had in my scrapbox yes, but i lateron switched to the present toroid which is much smaller 10x6x4 and i ordered it from ebay:

Verpies kept track on the used toroids during the Dally replication by severall members early in this thread, see the below post for the data on them.
Mine has severall toroids mentioned, but the 10x6x4 is the one i still use now:

There is a wealth of information hidden in this thread, so it pays off to take some time to scan through the first 65 pages or so.

Thanks a lot Itsu.
Indeed too much info but scattered and difficult to find.

Have you measured the limits of your width control? I want some between 60 and 80ns pulse to give rise at 6MHz where I have a good peak on my grenade and inductor together. I used your way to find my resonant points, and until now is the best way that worked for me. I only changed the ground connection of my fg. So I connect my fg red cable to the katcher's antenna, and black cable to the ground of grenade. So signal passes capacitively to grenade. I measured the response of grenade when grenade is fully connected to the bridge-capacitor-load combo. I placed my probe in parallel with grenade, counting also for the 5pf probe's capacitor in parallel with the bridge capacity. I looked for frequencies that excites both inductor and grenade together. I found one at 2Mhz which gives rise at 6Mhz to both of the coils. But firing it straight with 6Mhz the difference in amplitude is big.

Jeg,

i measured the width control (R9 in the ALLEGGA blue box) to be between 80ns and 500ns, but that does not "control" the width of the nano-pulse itself when i hooked up my nano-pulser there.
The original width control (74HCT02) of my nano-pulser has some similar range

This nano-pulse width itself is not controlable, it need a minimum input width (i think around 200ns) to function properly but for the rest it
"adjusts" its width to the presented load (50 Ohm resistor or open/closed 50 Ohm coax cable).


But i am not sure if i can follow you, as 70ns corresponds to 14MHz (http://www.calctool.org/CALC/other/converters/freq), so whats that about a 60-80ns pulse and 6MHz?
