H1 firing, closeup
View of an argon plasma at 1500A, with flash to illuminate coils. The plasma is on the other side of the ring conductor, twisting from top to bottom. The mirror in the middle is part of a periscope which allows "Clive Cam" to see the plasma along a chord parallel to the long axis. The copper bus bars in the mirror are the Toroidal Field connections. THe bellows contains Shaun's toroidal Mirnov array, and the 13mm tubing wrapped around the ring conductor near the edge contains David's poloidal Mirnov array.
