Hi,
for curiosity I would be interested in the same question. We have a
600 MHz magnex magnet no longer in use. Charging rods are available.
I would be happy to use this occasion to play at least one time
During the whole lifetime with these tools. -)
I fear, its impossible to perform a slow discharge. Of course you can open the main coil switch using the mentioned battery but this
Would end in a quench as well. One needs the external diodes, but at
Least in our case those are not available.
But maybe I am wrong and there is still an opportunity to play
Around with an old magnet …

Betreff: AMMRL: Bringing down a 500Mhz Oxford Magnet with a 9V battery?
A neighboring institution has 500 Mhz VNMRS system with an Oxford Magnet they are not using and cannot afford cryogens for any longer. They have inquired as to whether they should just let it quench.
We may have the power sticks, etc to take it down. Does anyone have a procedure for how this is done? Many moons ago we took down a magnet with a 9V battery, but the procedure has been lost to dust and time.
Thanks for any info you can provide.
