Thanks Dale,
I dont know about anyone else, but I am at the stage where I have
wound my toroid, and have ideas about polarizing the distilled
water ( in my case ) and need some time to get on with the
electronics - which is my field ( not the
chemistry/nuclear/valecy things :-) Hopefully I will get a chance
in the coming months.
I was at first dissapoined to read that I should have de -
oxegenated? the water before filling the toroid, but then relieved
to find that it might have re-oxegenated? within a week anyway, so
perhaps I didnt waste my time.
Another point that has held me back is the claim that an Overhauser
is far superior to a common or garden proton precession magnetometer
. ( but the manufacturer that claims this has a switch to go back
to normal PPM mode ??? )
I spent some time looking for the magic overhauser elixer -
"Tempone" , and Phil, quoting Keith Maddeen - I think- wrote :-
"The stability of the integrated intensity of the TEMPONE ESR bleach
has been
evaluated in the presence and absence of oxygen and found to be
stable for
hours. The ESR linewidth of TEMPONE solutions irradiated under
anoxic conditions
was constant in the postirradiation period. However, when oxygen was
added
postirradiation, the oxygenÂbroadened ESR linewidth decreased slowly
toward the
width observed in anoxic media, indicating consumption of dioxygen
by, with
concomitant production of, diamagnetic species in solution."
I haven't a clue what it means, but the "stable for hours" steers
me back to my distilled water filled Fisher Price ( Far East
lookalike ) toroid
I think that perhaps we are all waiting for the B-all & end-all
solution, when we ought to be finishing our individual prototypes
and compare notes ? , I am as guilty as any one ,
business ( thank heavens ) has distracted me, but I should have
some time soon.
