Two hearts
One valve,
Pumping the blood, we were the flood, we were the body and
Two lives
One life
Sticking it out, letting you down, making it right

Seasons they will change, life will make you grow, dreams will make you cry, cry, cry
Everything is temporary, everything will slide, love will never die, die, die

I know that birds fly in different directions
I hope to see you again

Living the dream, watching the leaves, changing the seasons
Some nights
I think of you
Reliving the past, wishing it’d last, wishing and dreaming
Seasons they will change, life will make you grow, death can make you hard, hard, hard
Everything is temporary, everything will slide, love will never die, die, die

I know that birds fly in different directions
I hope to see you again
Birds fly in different directions
So fly high, so fly high

When the moon is looking down
Shining light upon your ground
I’m flying up to let you see
That the shadow cast is me

I know that birds fly in different directions
I hope to see you again
Birds fly in different directions
So fly high, so fly high
So fly high, so fly high
So fly high, so fly high

  1. G'day im here to teach you how to create nuclear fission in 7 easy steps🤪

    Minimum requirements:
    -A vacuum chamber, preferably in a spherical shape
    -A roughing vacuum pump capable of reaching at least 75 microns vacuum
    -A secondary high vacuum pump, either a turbo pump or oil diffusion pump
    -A high voltage supply, preferably capable of at least 40kv 10ma – Must be negative polarity
    -A high voltage divider probe for use with a digital multimeter
    -A thermocouple or baratron (of appropriate scale) vacuum gauge
    -A neutron radiation detector, either a proportional He-3 or BF3 tube with counting instrumentation, or a bubble dosimeter
    -A Geiger counter, preferably a scintillator type, for x-ray detection and safety
    -Deuterium gas (can be purchased as a gas or extracted from D2O through electrolysis – it is much easier and more effective to use compressed gas)
    -A large ballast resistor in the range of 50-100k and at least a foot long
    -A camera and TV display for viewing the inside of the reactor
    -Lead to shield the camera viewport
    -General engineering tools, a machine shop if at all possible (although 90% of mine was built with nothing but a dremel and cordless drill, the only thing you really can't build without a shop is scratch building the vacuum chamber)
    Step 1. Assembly the vacuum chamber

    A quality high vacuum chamber is required for the fusor to operate. Sometimes an appropriate chamber can be found on eBay, but generally it is best to make one. Parts can be scrounged for several hundred dollars, or purchased new for $500+.

    Get two stainless steel hemispheres, purchase two corresponding conflat-flanges (8" flanges in my case), bore out holes for accessory flanges, and then TIG weld it all together. Flanges are typically either of the KF or the conflat style. Conflat can be seen in the image below as the flanges with bolts, and KF (kwik-flange) are seen as those with only clamps holding an o-ring on the mating surface. Only weld on the inside, never on the outside (since virtual leaks can be formed if both inside and outside are welded). If you've never TIG welded before, it would be wise to have someone with experience do it as the welds must be flawless with no pin-sized holes or porous areas to hold a vacuum.

    After machining, thoroughly clean the chamber and avoid getting fingerprints in it since these will outgas, which means at vacuum pressure molecules in the oil of finger prints or machining oil will become vapor and make it hard to maintain plasma stability or reach a good ultimate vacuum level.
    _________________________________________Step 2. Prepare the high vacuum pump
    Install the oil diffusion pump (or turbo pump if you have a bit of luck scrounging or a higher budget). Fill the pump with quality diffusion pump oil to whatever fill level the pump documentation suggests, attach the inlet to a valve which then connects to the chamber (see diagram), and attach the outlet to a mechanical backing pump capable of reaching at least around 75 microns (any higher and the diffusion pump will not operate properly or the oil will oxidize quickly).

    Make sure the pump is sufficiently cooled, many oil diffusion pumps require water cooling, smaller ones such as the one pictured can get by with a decent air flow.

    Once this is assembled, turn on the mechanical pump and wait for the vacuum to reach at least 75 microns. Next you can test the high vacuum pump by turning on the boiler on the diffusion pump. After it warms up (could take a while), the vacuum should rapidly drop below the single micron range
    _________________________________________Step 3. Build inner grid
    The inner grid (where the high voltage is applied) must now be built and attached to a high voltage feedthrough.

    It is best to use a metal such as tungsten for the grid wires since it has a very high melting point, and the grid will get extremely hot during high power runs.

    This can be built however you wish, as long as it resembles a spherical shape of roughly 1-1.5 inches in diameter (for a 6-8" chamber), it should work fine.

    The grid should be internally attached to an electrical feedthrough such as the one pictured in the second image. This feedthrough needs to be rated for the cathode voltage that will be used, typically 40kv is a good target voltage.
    _________________________________________Step 4. ASSEMBLE THE DEUTERIUM SYSTEM
    Deuterium gas is used as the fuel for this fusion reactor. You will need to purchase a tank of this gas (unless you wish to do electrolysis on heavy water, this process will not be documented here but nothing more than a small Hoffman Apparatus is required – higher purity gas can be gotten from a compressed tank).

    Attach a high pressure regulator directly to the tank, add an extremely fine-metering needle valve after this (or a laser drilled orifice in the range of 5 microns), then attach this to the chamber. A ball valve can also be installed between the regulator and the needle valve since needle valves are not shutoff valves.

    See the attached diagram now updated with the deuterium handling system.
    _________________________________________Step 5. High voltage
    If you can purchase a power supply (occasionally but not commonly found surplus) appropriate for fusion use, the high voltage becomes very simple. Simply take the output of the 40kv negative supply and attach it to the chamber with a physically large high voltage 50-100k ohm ballast resistor in series (large enough that its length will not flash-over if 40kv is applied to it in a plasma run-away or arc discharge).

    The difficulty is that it is often difficult if not impossible to find an appropriate fully assembled DC supply of this voltage level that is affordable to the amateur scientist.

    Pictured is my high frequency ferrite transformer pair, with a 4-stage multiplier seen behind it.

    If a fully assembled power supply (typically manufactured by either Glassman or Spellman), there are a few options:
    -Find an x-ray transformer, and if necessary either reverse the rectifiers for negative polarity or add rectifiers if it has none (an x-ray transformer core won't have rectifiers, it probably will if it is in its oil tank)
    -Build a switching high frequency ferrite power supply. This is what I did, however it requires a bit of EE experience since several aspects must be resonant and if it is ever taken out of tune, the transistors will burn out. Probably not the best option for people with little electrical background.
    _________________________________________Step 6. Setup neutron detection
    the tube. Either an all-in-one counter can be used, often made by a company called Ludlum, or a modular counting system can be made using NIM modules. The tube is surrounded by about 2 inches of moderating material such as wax or water. This is by far the most accurate and useful form of neutron detection, however the cost of a new tube is prohibitive to most people, and they are extremely rare on the surplus market. Also, counting equipment can become quite costly.

    NIM Configuration: If you chose to make a NIM setup as I have, the typical layout is a charge sensitive pre-amplifier at the head of the proportional tube, which is plugged into both a high voltage power supply generating positive polarity voltage appropriate for the tube (in the range of 800V-2kV generally). The amplifier also hooks into a shaping amplifier, which is followed by a Single Channel Analyzer (for setting the detection discrimination level), followed by a pulse counter and/or rate meter.

    Shown in the first picture is my NIM setup, the second picture is the pre-amplifier attached to a moderated helium-3 tube, the third picture is a bubble detector after being exposed to neutrons.
    _________________________________________Step 7. Fire it up
    Time to turn it on (don't forget to cover any viewports/cameras with lead! Also x-rays can pour out of ceramic feedthroughs so point them away from people. It is a good idea to be monitoring for x-rays where any people are present). The basic procedure is:

    -Turn on the roughing pump and wait for sufficient backing pressure, turn on the diffusion or turbo pump and wait for it to fully warm up or achieve running speed
    -Throttle the chamber back (with the valve between the diffusion/turbo pump and the chamber)
    -Ever so slightly open the needle valve to the deuterium tank
    -Turn up the high voltage until either plasma establishes on the camera, or you've reached 40kv and nothing has happened (don't forget, you only get one chance in your life to screw up with voltages of this degree)
    -If nothing has happened, keep admitting more gas and the pressure should keep going up. Plasma should form around 40kv at about 10-15 microns of deuterium.

    If all goes well, you should see on your camera the image below, and you should be detecting neutrons at this point.
    Thanks for reading if you even did

  2. I get emotional and sad every time I listen to it thinking about the world beyond the angels who are around and the people who are gone.. 🥺😔😭👼🏻 but I love how deep it makes me feel it's powerful and teaches me about life 💗
