Nearing Fusion

August 30, 2018 at 10:29 pm

Vacuum system – Complete Deuterium line – Complete Metering – Complete High Voltage line – Nearing Completion I expect to be fusing in the next few days, having spent today and yesterday preparing the high voltage line.  This involves stripping down RG-58 coaxial cable and attaching lugs and ground wires, […]

Deuterium Line and Turbo Controller

April 30, 2018 at 7:09 pm

Great news.  The Turbopump controller, an NT 150/360 has been fixed.  One of the power transistors was blown, and it’s now on the way back to me from ProVac.  ProVac to the rescue again.  Vacuum system is all done now.  Will spin up the turbo when the controller arrives to […]

Inner Grid Construction

April 8, 2018 at 12:30 am

The vacuum system is fully hooked up, finito – Except that I’m waiting to hear back on the turbopump’s controller.  It wasn’t driving the turbo at all, but it’s just a case of plugging a cable in when it gets back.  The Fusor can even be run without the turbopump […]

Vacuum Gauge Data

July 19, 2017 at 1:55 pm

One of the main features of the Fusor is remote operation, or as close to that as is possible without a huge amount of extra work.  I should be able to operate the Fusor without having to reach in and physically adjust or observe anything directly i.e. operate it while […]

Faraday Cage

July 12, 2017 at 5:20 pm

The Faraday cage is almost complete.  Constructed from galvanised grid iron and 25mm angle iron.  The top and bottom grids are permanent, side grids are removable and 2 hinged doors are to be added on the front and back respectively.  When in use, the plan is that the Fusor cart […]

Irregular Gaskets

June 30, 2017 at 3:27 pm

I ran into a bit of trouble recently with an irregularly sized conflat port, still working through it: In pulling a vacuum in a chamber, it must be sealed from the surrounding atmosphere/air. Otherwise the outside air will keep rushing in (a leak) as the vacuum pump(s) work and there’ll […]

DIY Mass Flow Controller Interface

June 29, 2017 at 1:45 pm

When the Fusor is in operation, it’s useful to know how much deuterium is entering the chamber for data collection purposes. Having some control over this flow is vital for exact operation of the Fusor. This is where a mass flow controller comes in to play, which both measures and […]

Procrastination and Fusion Nation

March 23, 2015 at 10:19 pm

Here I am again, returned after another long absence.   I haven’t been writing/blogging recently due to two things, one fairly large reason and the other more of a petty obstacle, I’ll start with the latter.     I sat my Junior Certificate Mock exams from January 29th – February […]

Batch of New Parts

September 5, 2014 at 11:02 pm

It’s been quite a while since my last post, but lots of new parts.  All the main parts (pumps, chamber, power supply, deuterium, neutron detection system) have either arrived or are ordered, meaning that all that is left are some small parts which are mostly on the way too.  Everything […]

More Parts And Funding Achieved!

August 5, 2014 at 3:39 pm

Great news – I received a donation last Friday which was enough to fulfil the funding goal of €10,000!  This is brilliant news as it means the Fusor build should be relatively smooth from here on.  Thanks again to every single person who has made this possible – all those […]
