Plasma 2

October 29, 2018 at 12:42 am

The Fusor has produced a few more plasmas.  See below video.   Plasma_run from Tom McCarthy on Vimeo.   What you’re seeing is a plasma inside the vacuum chamber.  The wires are the tungsten grid that’s connected to the high voltage supply.  Chamber at ~10 microns and begins at ~6 […]

Conflat Leak

September 8, 2018 at 1:29 pm

In my previous post I wrote that I was aiming to do fusion last weekend. Once the high voltage line was fully wired, I was ready to evacuate the chamber and test the high voltage supply – 30 kv, 20 ma.  Pumping down the chamber takes some time, usually upwards […]

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, […]

Vacuum Progress

March 30, 2018 at 1:25 pm

Today I’m grappling with a turbopump issue.  I’m using an NT 150/360 controller, and TMP 150 pump, both provided very generously be Provac Ltd.  They’re a great unit, but I think the Edwards RV3 backing pump is struggling to back them, and the system isn’t operating smoothly.   As noted, […]

HV Power Supply

December 28, 2017 at 12:52 am

Won an auction for a high voltage power supply “in working condition” last night on eBay.   $100 + $50 shipping from the US for a Matsusada 30 kV, 20 mA negative polarity supply.  It would be preferable to have a higher voltage for experimentation, but it’s a great starting power […]

Current Status #1

September 2, 2017 at 8:03 pm

An update on where the Fusor is at:   Nearly done, honestly.  A handful of jobs to do prior to completion.  Main ones:  I’ve to finish ordering deuterium, and arrange a high voltage power supply.  Once they’re here, they’ve to be installed and then I’m set to go.  I’ve got […]

JET Visit

August 5, 2017 at 8:58 pm

JET – Joint European Torus operates out of the Culham Centre for Fusion Energy, CCFE in the U.K.  It’s between Cambridge and London. Mega Ampere Spherical Tokamak, MAST, also operates out of CCFE.  It’s a huge campus and JET is the largest fusion experiment in the world.  Excluding perhaps the […]

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 […]

Welding

July 6, 2017 at 5:32 pm

Tried some welding today, MIG.  I’ve been making the Faraday cage with Dad, and he’s done the welding as he’s experienced at it, while I’ve done most of the cutting/grinding/drilling etc.  More about the Faraday cage and some pictures up soon.   I thought it was going to be quite […]

Moving On Up

April 13, 2015 at 8:00 pm

Encouraging news guys!  It looks like I’ll be able to move the Fusor to the National University of Ireland, Galway (NUIG).  There’s quite a ways to go yet, but I expect this to work out.   NUIG is the most convenient place for me, speaking in terms of distance to […]
