Homebrew 3 Channel Pure SIN Generator ( 0 ... 60MHz )

   Magamps are used in all sorts of highenergy fields including radioactive.  If the acsupply to the magamp is uhf captured on a dipole antennae.  Instead of just dumping the carrier so as to obtain the modulation riding the carrier we filter and store the carrier in a resonant cavity.  Effecting a lowering of the frequency and a rise of amplitude.  Waves sitting on top of waves and beside them.  In other words taking uhf and converting it into non radiating khz.  After enough power has been collected the magamp bias supply and control circuit can be powered by the ac input.  The amplification occuring at a low frequency closed circuit whilt the input is open circuit. A portion of the signal used to amplify itself.  Amplify.  To make larger.  Lots of short wavelengths summed to create a longer wavelength.  The faster something changes the more energetic. Something changing 330million times a second expressed as something changing only 60 times a second

I dont know if this is useful, but the cro i fried with my 3 channel ring had so many faults that seemed un related to the input channel. the faults were in the vertical amplifier,power supply and timebase ..separate,unrelated  faults it seemed ..I had a manual . I never succeeded in fixing it. It was a nice anritsu 100 mhz

This cat we chase sees pn junctions as cotton candy..so it seems

Hi mannix

RIP, sounds like you put some monster spikes into the CRO ground system.

were you feeding the ring with squares or sin? I'm guessing square/PWM?

Nice link about magamps, I will read that carefuly this evening.

I'm worried about spikes coming back through control coils and frying my RF amp chips and maybe also my DDS chips especially when I go to square wave mode.

Do you have any ideas for protecting semiconductor OPs against spikes? I'm thinking Transient Voltage Suppression (TVS diodes) which avalanche at say 70% of IC max and then in parallel to those put neons to take the brunt of the later current and so protect the diode junction, I'm wondering if the neon would be fast enough to take the heat. If the TVS fails it will go short so worst case is that the TVS are just pricey fuses.

Regardless of the amount of load flux or polarity of the load voltage, there is no net effect of load flux on control flux.

I see this as an isolation issue and that the mag amp can be used as a part of the feedback loop. This has been said before but I see in now a little different.

    Even tubes have a hard time with reflection.  That's why we have microwave ovens nowadays.  Standing waves would setup inside the tubes of the day and toast the grids.  Whereas the cyclotrons create a spoked electron field that is spun.  The moving charge of the electron bunch creating waves in resonant cavities of the anode as the spokes alternately align with the anode cavities.  Ingenious device.  And I believe it is at the heart of the matter with the tpu.
Free electrons will orbit at a given cyclotron frequency about magnetic field lines.  We now have moving mass simply by providing free electrons and a magnetic field..  Where does the energy come from that allows the electron to move in a predictable drift or current.  In a torroidal coil the electron drift will be determined by three forces.  The polidal field the magnetic field and the gravitational field.  One electron drifting 1mm a second isn't much power but billions of them is.  Again where does the power come from that allows an electron to move.  Does an electron moving from cathode to anode effect the cathode anode potential if the electron never reaches the anode plate?  Electrons have moved but never reached the other side of the capacitor allowing the capacitor to remain charged.  Unlike when a capacitor is discharged into a closed circuit there is no exchange of charged mass in the two capacitor plates.  But there was an electron acceleration in the field between the two capacitor plates.  Adda magnetic field perpendicular to the polidial field and the electron acceleration now takes on a curved path.  Stop the polidial field and the electron movement spirals about the magnetic field lines.  In a torroidal coil there happens to be a conductor field full of free electrons in geometric aligment with the electron drift about the magnetic field lines contained within the core of the torroid. One more time where does the energy come from that causes an electron to move or orbit a magnetic field line.
