Ameen Aydan ...admitted to the neutron club 9/19/20
Maciek Szymański - Admitted to the plasma club 1/27/21

This is a list of AMATEUR fusioneers and experimenters.

It can include private individuals who receive aid and
assistance which might include financial help,
equipment donation and professional scientific guidance.
i.e. students in high school or college doing a fusor
project, science fair exhibit, etc.

Plasma Club:

As of 8/20/20 the entire former plasma club listing has been purged and new rules listed below shall apply for entry into the plasma club. No exceptions!
If you feel your name has been purged, but that you meet or have met, in the past, all of the criteria listed below for inclusion, Please forward the posting URL in which you give all of the data and equipment mentioned below. If you only make 80% of the criteria, please work, accumulate and use your new 20% and re-enter a new posting with the below criteria and you will be added... private message me with the URL if you have questions.

New 2020 Official criteria for admission to the Plasma club.

As this site is dedicated to fusion by the amateur scientist and not to the dabbler with a glow in a jar, we are establishing a minimum criteria for entry into the plasma club. This is to prove a desire to perform and to create, to a useful degree, a learning system related to the study of electrical, ionic plasmas. This is to show and demonstrate a desire to enter into a the learning process and understanding of vacuum, high voltage and instrumentation that are normal to all fusion processes. One need not continue on to do fusion, but must pass the test of a person at least interested in and capable of demonstrating a functional system capable of studying and researching for their edification and knowledge, a useful plasma study device. We refer to this device as a "demo fusor" It is so closely bound to a real fusor, it is a virtual "work-a-like" system.

To be entered into the plasma club, you must have the following physical items displayed and reading in images to be considered:

1. Have some sort of suitable, "vacuum safe" vessel. (Common glass jars are not allowed. Suitable glass bell jars are allowed as are metal containers such as cylinders, spheres, crosses, or tees)
2. Possess a viable mechanical vacuum pump.
3. Have an electrical or electronic vacuum gauge. (common circular mechanical vacuum gauges that are purely mechanical are not suitable to satisfy this criterion.)
4. Possess or construct a fully variable, direct current high voltage supply capable of at least 3,000 volts.
5. Have and display a functioning high voltage voltmeter and current meter to measure these two electrical characteristics for the plasma under study.
6. Have a view port that will allow the user to view and take a photographic image of the plasma under study.
7. Have a centrally located, electrically insulated, grid of some rather symmetrical smooth form that will support the high voltage injected to create the plasma. (A jumble of twisted wire is not allowed)

To be accepted with the above items in hand, the applicant must have a history of postings that will allow those here to adjudicate the success of the effort. they are listed below.

1. Have reported in some minimal stream of postings the process of assembly over time.
2. To have shown in the post seeking inclusion into the plasma club, the following:
A visible image of the plasma within the grid. A full image of their system with instrumentation visible as well as the claimant in the image. (we hope you are proud enough to let us see yourself and your work all together). The applicant shall also include a statement of the pressure of the air or gas in the vacuum chamber, the voltage and current used to generate the plasma and image.

Names are not purged from this list unless you move onto the Neutron club listing.

The Plasma Club

Luc du Plessis - 1/4/2021 From the Netherlands. First plasma club member inducted under the new rules
Ed Meserve - 1/10/2021
Maciek Szymański - 1/27/2021

Neutron Club:

This usually demands that a pre-existing plasma club member indicate
that he has added deuterium and has either activated a material
or has supplied a neutron counter or bubble detector reading along with an image
of the system with counter, bubble detector or method of activation apparatus
visible beside the fusion apparatus with a full description of his
run with data taken. Obviously, no one can see neutrons being
produced,but we should see proof that you can actually record
their passage via some sort of suitable apparatus.

Basically, an applicant for the neutron club must present proof in both images
and a full technical data disclosure indicating fusion has ,indeed, taken place.
This evidence should show the detection system and the fusor setup itself
along with all of the operational conditions during fusion and data recording.
Any applicant may be questioned by any number of Neutron club members upon
application and submission of proof. They should be prepared to further
clarify or exhibit knowledge of the data or processes used.

See the strict rules for joining the neutron club at:

And a sample submission at:


The neutron club, as of 8/20/20, will now be separated into two groups.

1. "The Elite Fusioneers" Those fusioneers who have gone on to use fusion to neutron activate a substance and proven they have done it. (This is the key must-have criterion!) Activation will prove that the fusioneer has done more than barely "tickle" a neutron counter and then leave. This elite class fusioneer can also include those who have contributed in new areas of research and development in a manner that furthers or enhances future efforts by others. Most among the "Elite" are very serious fusioneers who stick with the effort and have a decent history of posting and assisting others.

2. "The Fusioneers" Those who have proven they have done fusion. This listing sadly contains a large number of mostly younger people who were only "in it to win it" and immediately left the scene. Fortunately, a decent number in this listing are notable, long time posters and as such have notations by their names representing some special points related to them.

These separate listings are organized by the date order, as much as is possible, of those qualifying under the rules. In some cases the date of original fusion (fusioneer status) is much different from the date that were admitted to the definition of the elite status. Both dates and any special data of merit are to be noted after the name, if known. No person's name can appear in both lists.

This neutron club listing cannot include fusion work done by organizations or
professional people involved in this work for pay or profit unless
the effort is done "on the side" as a personal effort.
i.e. Tom Ligon - Bussard fusion effort

The Neutron Club

These people have operated a neutron producing fusor or fusion system, (normally d-d fusion):
They have shown via rigorous examination, by their peers, that their finished product and data are all in order and certify that they have done fusion.
This represents a significant and signal accomplishment for a single amateur scientist or amateur group under proper supervision.

**********************NWNC - Youth Team Effort****************
This is a special group of rotating students at the high school level that continuously
grows and changes over the academic years. They have won many 1st place awards
each year and well over $160,000 in scholarships to advance there members'
education. Thanks to superb mentoring, they are safely guided through the
fusion effort as each group comes on board. All the best to this one of a kind
fusion effort! Like the energizer bunny, they just keep on going and going.....

This team endures over the years as new students enter the group and older ones matriculate out to colleges.
A fabulous hands-on effort thanks to the adult advisors involved in keeping everyone safe, teaching good practices along with the scientific method.
Not enough can be said about this fine effort. It is a pity that local active groups like this with adult supervision do not abound. We are blessed that there is at least this one.

I will attempt to keep this listing up dated should future
high school students be inducted into the Neutron Club.


While most of the above have used the particle colliding, inertial
electrostatic confinement, "Farnsworth fusor" device, this list is
not limited to this form of fusion. Any form of actual AMATEUR,
"hands-on", experimental,fusion research effort and its success
will be logged here.

It must be realized that this list is not regularly purged based on
moribund activity. It is, instead, assembled to bear witness to any
and all who have put forth some fusion related effort in the past or
are working at present in the effort. Some of the folks on this list
have long ago departed or ceased work in their fusion quest.

I think these "rules" are good ones, Richard, and I commend you for your diligent maintenance of this list. As you say, it's a true testament to the measure of interest in this subject around the world.

Thanks for you tireless efforts.

Due to the new stringent requirements to be placed in the "plasma Club", as of November 2020, not one application has been received. Is this a good thing? I think so.

The plasma club was originally created to act as a "holding pen" indicating a significant accomplishment for what was hoped to become future fusioneers. Unfortunately, it turned out to be, in large part, a landing zone for rather feckless DIY folks. Most were drawn in by easy access to some form of fame for having their name in a listing of successful "doers" on a fusion site. We have determined to no longer reward folks with a mangled wire internal electrode held within an inverted peanut butter jar with an ill-defined glow in it on our fusion site.

Naturally, we applaud any and all efforts to make a crude demo plasma device and will continue to gladly accept all images and efforts taken in this direction. Nothing has changed in this respect.

Currently, as configured, the plasma club is a haven of recognition and reward for those bold enough to be there. Being there is an honor and allows any and all there, "breathing space" and time to take the final critical steps towards actually doing fusion, if they so wish.

I imagine the plasma club may remain moribund and only pick up an occasional soul. It costs too much in physical effort, the doing, cash expenditure, and scrounging to wind up there and remain there for long. 80% of the work for becoming a full neutron club member is already done, if someone succeeds in being admitted there! All names of most plasma club members will continue to be purged from that list once they do fusion and are inducted into the neutron club. (Our highest honor) I would imagine the future names in the plasma club will be very few. Perhaps, the plasma club will even remain empty most of the time due to a much deserved promotion, to the neutron club, of those already lauded and recognized in the plasma club who make the extra 20% effort.

I suspect that under the new plasma club rules that a new plasma club member will shortly move on to fusion and thus be purged from the plasma listing. When I set out to build my system, I did not want to have to build it twice, so I designed it from the beginning to be a fusion capable device. I achieved my first plasma on July 29, and my first fusion on Sept 12 of the same year, in less than two months.

Bob, lets face it. We're old, if we don't do it while it is fresh in our minds, we forget. Plus, we are overloaded with skill sets acquired over a life time and have some disposable income, fabulous junk boxes and no small number of machine tools. The youth in many instances tends to be drawn to this and that thing that seems fun and interesting, but tend to have short attention spans, limited hands-on skills and rarely any money. As always, the best among us perseveres.

This is, getting down to the basics, a site created to encourage someone to do actual fusion via a fusor (the easiest device.) As such, anyone wanting to do this at some point now has an achievable but still straight forward intermediate step - they must build a real science based device that proves they are serious. Achieving this status is very doable and certainly get's one closer to a real fusor but both at a far lower cost and without the need for a potentially lethal power supply.So besides earning that status they get to prove their mettle by building a real scientific instrument that while not all that difficult (but does require purchases of real equipment), still requires enough effort to reward a person that truly is interested and dedicated towards the goal this site was create for.

I'm happy to announce the new plasma club went active recently and now contains two names of folks who have met the strengthened requirements for membership. It is expected to grow, though not as fast as the old "glow in a jar" forum did. Names will be removed as these proven winners are inducted into the fusioneer listing, the Neutron Club.
