Re: Visit to EPFL's Tokamak Fusion Reactor

Hi, since I was the other person Werner mentioned, let me chime in with some pictures also ;) TCV has many vertical coils, clearly visible from the outside. Depending on how those are powered, many different plasma configurations and shapes can be realized. coils.JPG View towards the center of the t...

Austrian Fusor

Hello everybody, here is the current status of my Fusor project, on which I've been working on since summer 2014. Fusor_small.JPG As a chamber, I'm using the classic 6" Wagner hemispheres approach. The chamber has a total of 6 CF-40 flanges. The forepump is a Alcatel 2010 series dual stage rotary va...

"Compact Fusion Reactors": lecture at CERN

By accident I recently stumbled across this talk: https://indico.cern.ch/event/382453/

Copies of the transparencies and a video of the lecture itself are available also (see the above link).

Enjoy!

Re: selfmade MCA / gamma spectroscopy setup

Out of curiosity, I did another analysis - this time of naturally occuring spring water with significant radon content. The sample I used is from the "Hedwigsquelle" in Bad Zell, which is a nearby health resort (that also uses the radon-containing water for some treatments). I obtained two canisters...

Re: selfmade MCA / gamma spectroscopy setup

Recently Doug Coulter sent me two Na:I detectors. Using those and the MCA described in the previous post, the spectra look much more interesting / useful. uranocircite.jpg pitchblende.jpg cs_small.jpg radium_small.jpg Of course, since most of the active nuclids being members of the Uranium-Radium de...

Re: new automated vacuum system

Hi,

thanks for the information! Interestingly, I've also used the same approach using automotive heat exchangers. Not tested yet, however -- I'm still missing some parts.

Looking forward to your pictures!

Re: new automated vacuum system

Hi!

I like your setup - compact and yet flexible!

How exactly does your water cooling loop for the Diffstak look like? I'm especially interested in your radiator and its size. What coolant temperatures can you achieve in steady state?

Thanks a lot!

selfmade MCA / gamma spectroscopy setup

Hello! Recently, I've been working on a 12-bit multi-channel analyzer to be used with scintillation detectors that use a PMT as the primary amplifying stage (as opposed to a photodiode). Since I only have a BC-412 plastic scintillator ( Datasheet ) at this point, the main aim was not primarily to do...

Re: European Fusor

Very clean and professional setup, Werner! That feedthrough of yours is truly massive! Do you already have plans for the vacuum chamber; are you going for a standard spherical setup or a larger cylindrical tank (probably more flexible and necessary (??) to accommodate the feedthrough)? Can't wait to...

Re: Another look at plain old scintillaing plastic.

Hi Peter! Nice to hear from you again - how's your Fusor coming along? Thanks for the pointers: I'm afraid I can't get my hands on a DSO very easily, but I'll check out the Software you mentioned! But I don't expect do be doing spectroscopy that soon, since I have to get the low-level stuff working ...
