The end of in-vessel activities is finally upon us.  During the last week several key activities have been complete. The final alignment of the ‘High Resolution Thomson Scattering’  diagnostic has been carried out.  This system provides a powerful laser beam which passes through the plasma.  The laser light scattered from the electrons in the plasma gives information about the temperature and density.

Perhaps the greatest milestone is the installation of the last plasma-facing tile inside the torus.  This essentially marks the completion of delivery of the new ITER-Like Wall.  Very few in-vessel activities now remain and the end of the shutdown seems to be approaching us quickly.
