Steven Udotong Fusor Progress
Posted: Fri Dec 15, 2017 11:03 pm
Hi Everyone,
My name is Steven Udotong.
I have recently made some progress in the construction of my fusor system. I was assisted recently with some recommendations from users on fusors.net to procure a vacuum gauge which had me blocked for a decent amount of time, it was hard to find manual compliments for the pressure gauge I had. I ended up getting a slight discount for a EDWARDS PRM 10 PIRANI GAUGE HEAD on ebay.
Here are the major parts I have collected and completed most of the assembly including hole drilling, welding, and fixing the inner grid with the help of some professionals. (Also secured D2):
3 CF halfnipples
Vacuum Pump
2x Swagelok SS
3x STAINLESS STEEL 6" DIA. HEMISPHERE
2 CF Flanges 8"
Thermocouple
welding
view port
vacuum pump oil
High Voltage Cable
Camera
gatevalve/CF reducer 40 --> 2.75
1.5" Accelerator Grid
low pressure gauge
TV monitoring system
pancake geiger counter
fine needle valves
ADAPTER,SS,QF40 TO 9"OD ASA FLG
9" OD ASA FLG Gasket (ECONO RING, ASA4, BUNA, 6.75"OD, 5.25"ID, O-B256)
varium diffusion pump
Wing Nut Clamp, for 2" Tube OD 4518K74
Ultra-High-Vacuum Tube Fitting Ring, for 2" Tube OD 4518K65
12V DC Power Adapter Supply 2.1mm 1A CCTV
Brass Fittings
Power cord Pressure gauge
HV Power Supply
Variac AC Transformer
HV feedthrough
Gas Reservoir
Shutoff Needle Valve
Shutoff Valve (x2)
Stainless Steel Tubing
Edwards Controller
Gas Regulator
Hose connecting Diffusion to vacuum pump + adapters
Gate Valve 2.75" CF Conflat Flange
15 FEET 1/2 BRAIDED GROUND STRAP GROUNDING BARE PURE COPPER FLAT BRAID
Small knob for fusor (Home Depot)
Reducer, Brass,1/4 In. x 1/8 In.,
Hose Barb Male Connector 1/4 ID Hose X 1/8 NPTF
Hose Barb,3/8 In Barb,3/8 In FNPT,Brass
Union,Low Lead Brass,Comp,5/8In,
Hose Barb, 5/16 In Barb, 3/8 In MNPT, Brass
3/16 HOSE BARB 1/4" MALE NPT PIPE Straight Brass Fitting Water Oil Gas Air Fuel
Parker 3/8" Compression Brass Union 62C-6
Regulator Hose barb fitting; left-hand threaded, 5mm
Fine metering valve hose fitting
Ultra fine metering valve hose fitting
2.75” O-ring
8” Flange O-ring
Inner grid wire‘
Copper braided wire
Pressure gauge clamp
Pressure gauge o-ring
KF-40 (NW-40) to KF-16 (NW-16) Conical Reducer, 304 SS, Vacuum Adapter #A53B LW
Brass reducing adapter
LOT OF 6 SOLID BRASS 1/4" TO 1/4" FEMALE THREAD ADAPTOR AIR FITTING BB-6467
Vacuum tape
EDWARDS PRM 10 PIRANI GAUGE HEAD D021-66-000
DEUTERIUM RESEARCH Gas (Airgas)
Please see this schematic detailing my connections and the methodology of my connections and setup. The color green was what I was using to signify that I have secured the part and the number+letter combination correspond with my spreadsheet for all the materials in the project.
Please see the following pictures of my setup.
Apologies that the current pictures and setup are not great right now but I will be further working on connecting everything together properly and have better pictures to show in the very near future.
My next steps are:
1) Conduct the vacuum test now that I have the proper vacuum gauge and pull proper pressure within the range 200 microns or so.
2) Conduct the plasma test and submit results.
3) Get approval of setup from a member of the site in New Jersey and conduct the Neutron Test and submit my entry.
I have learned so much, in this process and look forward to continued growth and experimentation when I conclude.
I'd like to request to be added the Scroungers List as I introduced myself in the past but my lack of communication may have had me purged.
Eager to hear any feedback on anything and everything. Once again, sorry for the poor communication but thanks again to many of you that assisted me whenever I have sporadically had questions and others offline that I was in contact with over email.
