If the polarimeter is equipped with a temperature control system, set the required temperature for your sample (if relevant to your experiment). Step 4: Set the Wavelength (Optional) If your polarimeter has an adjustable wavelength feature, set it to the appropriate wavelength for your sample. Simulations of performance for a projected ITER baseline discharge show the TIP diagnostic will function as well as, or better than, comparable existing systems for feedback density control and that finite temperature effects will be significant in ITER even for moderate temperature plasmas and can lead to a significant underestimate of electron density.
