Gun Conditioning, Side Panels On

We are now into the third week of installation. The “baking out” procedure has been completed; the FEG has been placed back onto the column and charged with sulphur hexafluoride gas (SF6). The gun is now being conditioned, i.e. the high tension (HT) is slowly being brought to 200 kV. The column is also being pumped out. Meanwhile, the side panels have been attached to the frame. We are getting ready for the beam!

As usual, here are some pictures from the installation.
