Wobbler Pictures

This is a picture of the center oscillator, which rotates the sample horizontally about the vertical axis. The pivots are connected to the sample holder vertically.


This is the back side of the center oscillator. You can see the two magnets which are epoxied in place. The stack of magnets which moves in and out of the driving coil are held in place by these small magnets.


This is a view of the fully assembled oscillator connected to the cryostat probe. The sample is also mounted and held in place by a springy metal, I belive copper-berilium- need to check this: if you could comment on this Bud. This is the front end. One major improvement needs to be in how the wires are held in place. This grey terminal block is too large, and the connectors we were using are too large.


This is the back side of the oscillator connected to the probe. This is where the most improvement needs to be. Having the two coils (one driving- one pickup) horizontally in line created some issue with the cryostat. They would get pushed in by the sides of the cryostat and would then become misaligned. They need to be smaller and more robust.
