The injector, an upgraded DINA-5 model, is supported on a mobile cradle that permits its path through the plasma to be varied by ±3° poloidally. In parallel, a dedicated bidirectional (two vertical opposing views) multichannel spectroscopic diagnostic, incorporating fiber arrays, an f/1.8 spectrograph, and a back-illuminated charge-coupled device, has been installed to obtain Doppler line shifts and widths (around 529.2 nm) with ~1 cm spatial resolution. | The injector, an upgraded DINA-5 model, is supported on a mobile cradle that permits its path through the plasma to be varied by ±3° poloidally.
