A new mass resolving neutral particle analyzer was installed on the HT-7 tokamak.The analyzer is constructed with electric and magnetic fields and is calibrated over an energy range of 0.2—50keV.The new analyzer provides a wide energy range,mass resolving,perpendicular scanning charge-exchange diagnostic.In Ohmic-heated deuterium discharges,the analyzer provides the measurement of deuterium ion temperature over a range of viewing angles,and radial ion temperature profiles can be obtained.
