This is with D2 and only 1KV. The sphere is hand formed .010 Ta wire
1.3" dia. A 25 mm lense feeds the fiber optic cable to the Ocean Optics
spectrometer.

I expect my 30KV power supply to be repaired this week.

Congrats, Wayne. I have always been intrigued by how the bugle jet appears to materialize "out of nothingness". An "event horizon" as it were.

Congrats, Wayne. That's a beautiful picture with great resolution; did you just take a regular digital camera and snap a photo through the viewport?

Raymond-Thanks
I used a 8 Meg camera with a macro setting through the 25mm sapphire
window. The 19" display monitor gives a poor quality image.
We can operate this Saturday.

Jon-Thanks
At lower pressure the center becomes faint and a green jet appears.
Guess it is the electron path. Next time, I will use the RGA. Getting ready
for more power.

Very nice. Hope you post pix when your PS is fixed. BTW I have seen several Ocean Optics spectrometers on e-bay but most of them were really expensive. I ended up getting a SPEX spectro (old style and big but with computer controls) Any tips on getting a good deal with these integrated units like the one you have?

Thanks- The Ocean optics is easy, but a good SPEX with a PMT will give
scientific measurements. I have a 1.25 meter SPEX which I plan to use
fore future measurements. This resolves 80 mili angstroms.
OE makes a "student spec for $1200.
Your SPEX with a fiber optic is a good plan.

Nice work!

The time that Tom Ligon and I spent with EMC square's ocean optics spectro looking at doppler broadening was most instructional. We had his unit spec'd with a special slit and grating to focus in on the H beta line. That is the small peak in your image to the left of the large H alpha line.

Keep up the good work.

Is 0.08A enough to tell hydrogen from deuterium?
