The ITER diagnostic neutral beam (DNB) is to be used to diagnose He ash content of the ITER plasma during its DT operation phase using the CXRS diagnostic technique. The measurements shall be performed using a 100 keV 20 A neutral hydrogen beam. The measurements are performed at 21 m from the place where the beam is produced. It uses the step of ion beam production, acceleration, neutralization and charge separation to achieve the desired beam parameters.
About 8000 such blocks are to be manufactured from special grade steel. These blocks will be delivered to Europe, Korea and ITER site.
Being manufactured at Avasarala Technologies Ltd., Bengaluru.

Often termed as the world’s largest thermos, the cryostat is a 30 m tall and 30 m diameter outer vacuum shell of the ITER machine to insulate the machine and its components. It is a 54 piece puzzle manufactured by M/s L&T Hazira and assembled at the cryostat workshop of ITER-India at the ITER site. Key technologies include:
An external heating system for the ITER Plasma
Heating power of about 20 MW
8 sources; about 2.5-3MW/source made using amplifier chains, Power Supplies Frequency range: 35-65 MHz
Currently R&D activities ongoing on two technologies – Diacrode and Tetrode
In collaboration with Thales Electron Devices, France and Continental Electronics Corp. USA
Promoting Development of RF technology in the country.
The Cryostat Base section, an In-Kind Contribution to ITER from India was installed at the Tokamak pit during the wee hours of 28 May 2020. The structure weighing approx. 1250 Tons, over 29 m diameter and 6 m tall was placed with positional accuracy of less than 3 mm with only very small gaps around.
A ‘Commit to Deliver (C2D) event was organized by ITER Organization at ITER site on 16th June 2022 to mark the installation and completion of the supply of equipments related to the Component Cooling Water System (CCWS), Chilled Water System (CHWS) and Heat Rejection System (HRS). These supplies are a major part of the cooling water system capable of removing 1150 MW of heat generated during ITER operations.
The ITER-scale negative ion source - SPIDER was officially launched at NBTF facility Padua in June’2018. Recently it achieved another milestone. SPIDER was operated while applying extraction and acceleration voltages, obtaining the first SPIDER hydrogen beam.
The control (Variable Frequency Drives, Electrical Panels etc.) for the ITER Cooling Water System (CWS) equipment like pumps, valves etc. will be housed in a large "E-House".
