ITPA Topical Group Meeting on Diagnostics

Thirteenth Meeting, Chengdu, China

October 29 - November 2, 2007

Chinese Meeting

Agenda:

Development of methods of measuring the energy and density distribution of confined and escaping a's

Assessment of the various options for the Vertical Neutron Camera to measure the 2D n/a source profile and
            asymmetries in this quantity, and assessment of the calibration strategy and calibration source strength needed

Progress in the field of first mirrors

Development of measurement requirements for measurements of dust, and assessment of techniques for
            measurement of dust and erosion

Assessment of the integrated measurement capability of the diagnostic systems relative to the specified measurement requirements
