We took our Fusor out of its shell yesterday, partially because we want to install a new camera that should arrive today. As we recently remembered that we have an acrylic bottom plate, that might make for nice pictures for a while.
First, a picture in the room. By the door, the emergency off switch for the HV system. Left: electronics, low right: rough pump, underneath: HV system (NST plus CW + measurement)
Then, some close-ups:
Variac, sensor board, rough pump:
Then we took the cart out of the lead enclosure:
Next, some vulnerable items come off:
Camera on arm with mirror
The gas feed with the needle valve, solenoid, mechanical shutoff, and Arduino:
The Pirani gauge and Arduino, the latter of which I am hoping to move away from there and into a shielded container today
The turbo pump controller and its Arduino:
Now the prep work for the new camera. First the view from the bottom, needs some cleanup:
The place it sits on:
And with its new channel and hole for the camera and its USB cable. The cardboard-cutout stands in for the camera.
And that's it for today. Now we wait to receive the new camera.

Re: Dismantling our fusor
Very impressive
Just a quick note
You might want to shield a lot of your electronics. HT flashovers let go a lot of EMI that tends to destroy solid state electronics
lots of ferrite beads on cables and earthed metal boxes to put the electronics in

Re: Dismantling our fusor
Thanks for the note - I just stopped by our electronics store and bought a bunch of metal cases, we'll see what we can do. It's been one of our worries, along with discharge spikes.
