The pole-pieces have not been rigidly attached to the main magnet H-frame, realistic machining tolerances making this impractical. Instead a Neoprene rubber (0.8 mm) spacer has been inserted between each pole-piece and the frame. Careful adjustment of the three fixing screws for each pole-piece varies the compression of the Neoprene so that the pole faces may be adjusted to be precisely parallel, thus maximizing the volume of best field homogeneity. A field homogeneity better than 1 part in 10,000 over a volume of ~2 cm^3 has been achieved.

A sample coil is mounted centrally in the gap of the magnet. A short length of NON-MAGNETIC low-capacity coaxial cable is used for connection to the electronics chassis.

Hi Esteban,
Yes, I am sure.
If you read the articles, they are talking about the methods of measuring the spectrum of nuclear magnetic resonance for different samples placed inside a testing machine. The testing machine will not work without building it to some very close tolerances:
The sample to be tested is inserted between the pole pieces of an electromagnet that has been adjusted by three setscrews to produce an extremely homogenous field in a space of 2 cubic centimeters where the sample is placed.

When reading the text, it became very apparent that this equipment has no bearing on using an antique IB metal detector to find buried treasure, or using a passive ferrite coil with an attached RF detector circuit to locate buried treasure. The articles describe a method to measure the nuclear magnetic resonance of samples placed in a testing machine, not methods to locate hidden samples at long range with receiver coils. And the principle of operation is not related either, as it requires extremely high precision machining as well as adjusting physical dimensions to optical tolerances (1-2 wavelengths) in order to produce a extremely homogeneous magnetic field (better than part 1 in 10,000). Then it requires inserting a sample into this high-precision 2cc field to exhibit precession data when the field is removed.

Do you think any of this is related to the PD?

Best wishes,
J_P

you say that this project of Andy Flind modified works as LRL... and nobody else.

But you put that claim (as with others) and then gave no explaination, no modification plans, no testing procedure, nothing...

just claims. As Dell. As Hung. As any other LRL-fanatic but with add of pepper...

same stuff... but you also add some stamp-sized schematics... that's the difference! :lol:

That, of course, change totally my point of view about your claims... :D

Kind regards,
Max

Hi Esteban,
I am not sure I understand you. Are you saying Andy's MFD modified with a loop and "other few" to demonstrate buried treasure causing bar graph LEDs to light is related to a laboratory test instrument measuring the precession of protons of a sample placed in an extremely homogeneous magnetic field? :shrug:

I thought you were originally saying the PD is related to the nuclear magnetic resonance spectrum measuring instrument which uses the proton precession method to collect data on samples that are inserted. It is hard for me to imagine that Andy's MFD modified, or the PD are related to this laboratory instrument.
Are they?

Best wishes,

Is a simple comparisson. Also the article by Andy Flind doesn't describe a method for to find treasures, is a MFD (Magnetic Field Detector), and here acts as receiver device. With some mods is useful for to locate metal buried for long time.

The ferrite part of the PD acts similar to the MFD.

I think is possible to modificate the Magnetic Resonance Spectrometer (MRS) as a LRL device. The theme is to found a sensor or antenna wich umbalance a delicate adjustment. The "phenomenon" causes for metal buried for long time can umbalance the equilibrium.

Hi Esteban,
Maybe you're right.
But in order to show a change in the MRS tester, a sample must be placed in the test cavity to be excited by the precision magnetic field for the sample's precession to be measured. When the sample is not inside the test cavity, then it is not possible to see precession data of the sample. An antenna in the test cavity would only show the precession data for the material the antenna is made from. You think that when the antenna is placed in the test cavity and pointed in the direction of a treasure, then the antenna metal precession data will be disturbed by energy collected from the buried treasure?
