The Diagnostic Package includes India's participation in:

• X-Ray Crystal Spectroscopy (XRCS) : Set of spectrometers (X-ray crystals, Detectors , Vacuum chamber), Calibration source, Instrumentation & Control (I&C)
• Electron Cyclotron Emission (ECE) : Set of Michelson Interferometers & Radiometers, Polarization splitter unit, Transmission line, Calibration source, Instrumentation & Control (I&C)
• CXRS : Optical Fibers, Visible Spectrometers, Detectors, opto-mechanical components like filters, mounts, Instrumentation & Control (I&C) C
• Upper Port- 09 (UP#09) : Complex integration with Interspace Support Structure (ISS) & Port Cell Support Structure (PCSS) etc., and customization for CXRS (Edge)

In order to establish measurement techniques for low loss transmission of ultra-wide band frequency range of 70 GHz – 1000 GHz, a prototype Fourier Transform Spectrometer has been developed to establish in vacuum attenuation calibration for an 8m transmission length.
