Re: BTI-PND dosimeter microbubble formation when overheated

Interestingly, I just looked back at the pictures I took of my heated dosimeter after different amounts of time, and I noticed that the micro bubbles from the heat do not appear to grow the same way neutron bubbles do. There was very minimal growth if any.

Re: Neutron Club Application- Zan Chaudhry

Thank you everyone for everything. I have been looking forward to this for a long time. But this is nowhere near the end of my fusor endeavors. I'm looking forward to more progress in the future (chamber upgrades, grid upgrades, new gauge, calibrate my 3He tube, and ion guns!). I'm thinking about ta...

Re: Neutron Club Application- Zan Chaudhry

Okay, I've got a rerun. 1. 10 minute operation. 2. 24-35kV voltage. (lots of variance, mainly in the mid 20kV's) 3. 40 to 60 mA (I actually blew my variac's fuse at the end). 4. 10 micron pressure 5. Grid picture attached. 6. Dosimeter pictures attached. 7. 73 b/mrem sensitivity 8. 8 inch dosimeter ...

Re: Neutron Club Application- Zan Chaudhry

I think I've got it all now: 1. 12 minute operation 2. 35kV average voltage 3. 24mA average current 4. 5-15 micron pressure (on my gauge) 5. I attached pictures of grid. Most of the time it was in the golden state. 6. I attached dosimeter images. (the bubbles are only in the top because my dosimeter...

Re: Neutron Club Application- Zan Chaudhry

But wait. I was not using the tube on this test. I was using a bubble dosimeter. And I also wasn't using 16kv, I was using 32.

Re: Neutron Club Application- Zan Chaudhry

Okay, so a lot has happened. My small x ray transformer turned out to have half a burnt secondary that was kind of intermittently working. So I replaced it. My dad happened to have a broken AMX 4 x ray that I opened and removed the transformer from. It's rated at 120 kv 25 ma and it's pretty big. So...

Re: Bubble Dosimeter Group Purchase

Okay, I've officially purchased two dosimeters. 100keV threshold, 40-80 bubbles a mrem. If someone wants to purchase with me respond soon. The ship date to my house in Maryland is August 16.

Re: Neutron Club Application- Zan Chaudhry

Thank you very much for the information. I'll give him a call and see if he has time, and if he does I'll see what we can do. Hopefully I can get my tube working, but I'm still going to get a bubble dosimeter (If anyone wants to group purchase with me: http://www.fusor.net/board/viewtopic.php?f=13&t...

Bubble Dosimeter Group Purchase

Hi everyone. I'm buying bubble dosimeters, and I'm wondering if anyone would like to split with me and buy one. I was planning on getting two since that's the minimum purchase amount, but I could do one more, but I don't really want to mass purchase. I've never done anything like this before, but I'...
