Nuclear Magnetic Resonance (NMR)

@Smudge:  would a "140 mm / 60 mm / 20 mm" Feritt ring magnet also work? It seems to be difficult to get disk magnets larger than with a 100 mm diameter.


With the 140 mm ring magnet the 100 mm circular water tube would be in the middle of the ring (between the 60 mm inner diameter and the 140 mm outer diameter).

   D/l the user manual pdf for that unit and refer to page 56. At the top is says you also have a Power Amp built into it. Be ware of it tho. Do not over drive the RF amp as you will destroy the pre-amp side in it. Your SG says it will do max 10 W to an 8 ohm load. You will be doing a 50 on the RF side. Start out low voltage and low amplitude to get the best results.

@thay: thank you for the information, helps a lot.

I tried to find the user manual PDF online, but no success. Do you have a link? Or you could attach the PDF file?

   I will try but the last 3 times it has just hung up for me:

@thai: Sorry, I thought you have found a PDF user manual of the RF power amplifier from China. But it is helpful that you read the function generator manual more carefully than I ever did.

I could 3D-print a circular tube as specified by Smudge, see the attached photo. My Creality Ender III Pro which I bought recently for EUR 230.-- managed the difficult bridging when printing the hollow tube without supports. Clearly, I did not want supports inside the circular hollow tube.

If an experimenter needs a similar circular tube I am willing to print one and send it by mail. The experimenter either pays me EUR 1000.-- or simply asks nicely.

Now I need to know, whether (140 mm / 60 mm / 20 mm) ring magnets which I talked about in my post above will be good for the replication (instead of disk magnets).
