Participating in the ITER fusion project being conducted worldwide by various countries, to produce power for consumer consumption.
Winding of the superconducting magnet for the tokomak fusion reactor is currently underway.
ITER (originally the International Thermonuclear Experimental Reactor) is an international tokomak (magnetic confinement fusion) research/engineering project that could help to make the transition from today's studies of plasma physics to future electricity-producing fusion power plants. It builds on research done with devices such as DIII-D, EAST, KSTAR, TFTR, ASDEX Upgrade, Joint European Torus, JT-60, Tore Supra and T-15.
Although there are over 200 projects for the ITER fusion reactor worldwide, the winding of the superconducting magnet required for the reactor is still in the prototype stage.
The prototype for the European ITER project has been awarded to Mitsubishi Japan.
PADMCO is currently in the process of developing the winding set up to wind this magnet for IPR-India and anticipates having this in production in 4Q2011.

Project- Large Hadron Collider, popularly known as the Big Bang Theory- Europe. (Interactive Lab in India- Raja Ramanna Centre for Advanced Technology (RRCAT).
PADMCO supplied the winding equipment to RRCAT to subsequently wind the magnets in large quantities.
The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator, a synchrotron intended to collide opposing particle beams of either protons.
To smash the protons very powerful superconducting magnets are lined inside the 27km tunnel of the LHC.
The winding equipment to wind the superconducting magnets was made by PADMCO in a record eight months.
The niobium-titanium (Nb-Ti) magnets will operate at 1.9 K to allow them to run safely at 8.3 T. Each magnet will store 7 MJ. In total the magnets will store 10.4 GJ. Once or twice a day, as the protons are accelerated from 450 GeV to 7 TeV, the field of the superconducting bending magnets will be increased from 0.54 T to 8.3 T.

Development of technology to wind the superconducting magnet required to facilitate the running of a K-500 reactor, to produce power for consumer consumption.
Development of Magnetic Field Mapping instrumentation for the Cyclotron
One of the major components of this cyclotron is the super conducting magnet coil which produces very high magnetic field required for rotating high energy charge particles. The magnet coil of the K-500 Superconducting Cyclotron is immersed in liquid Helium (4.2K) in a specially built stainless steel Cryostat. This Cryostat consisting of super conducting coil is finally placed inside iron core magnet producing magnetic field upto 7.0 Tesla.
The technology and set up to wind this superconducting magnet was developed by PADMCO.
PADMCO also developed the entire set of magnetic field mapping instrumentation for the Cyclotron.
The superconducting cable used for winding the coils is multi filament array composite superconducting wire (1.29 mm diameter) having 500 filaments of 40 μm diameter Nb–Ti in copper matrix which is embedded in OFHC grade copper channel (2.794 mm × 4.978 mm) for cryogenic stability. The basic structure of coil consists of layer type helical winding on a SS bobbin of 1475 mm ID × 1930 mm OD × 1170 mm height. The bobbin was afterwards closed by SS sheet to form the LHe chamber. The total weight of the coil with bobbin was about 6 tonne and the total length of the superconducting cable wound was about 35 km. Winding was done at very high tension (2000 PSI) and close tolerance to restrict the movement of conductor and coil during energization.

Scientists make superconducting magnet
Programme to use cryogenic technology
- A magnetic field of about 48 kilogauss
- Superconducting component is about 6.5 tonnes
- Cost of cyclotron is Rs. 93 crore
KOLKATA: Scientists in the Department of Atomic Energy's Variable Energy Cyclotron Centre (VECC) here have made the largest superconducting magnet in the country, energised to produce a magnetic field of about 48 kilogauss. (The earth's magnetic field measures 0.3 gauss.)
The superconducting magnet "is the heart" of a K500 superconducting cyclotron "machine" being set up at the centre.
It is part of the programme to employ cryogenic technology on an industrial scale, Rakesh Kumar Bhandari, Associate Director, VECC, told The Hindu on Monday.
The superconducting component of the 100 tonnes heavy magnet is about 6.5 tonnes.
It is kept at minus 269 degrees Celsius. It has a diameter of nearly 3 metres and a height of 1.3 metres.
MRI applications
The technology has applications in magnetic resonance imaging (MRI), medical diagnostics, energy storage and the rapid transport system having magnetic levitation devices.
The cyclotron, work on which began in 1997, should be ready in two years.
It will be the seventh such superconducting cyclotron in the world.
A superconducting cyclotron is a system in which advanced superconducting technology is used for producing very high magnetic fields for guiding the charged particles during acceleration to high velocities.
Major improvement
Being set up at a cost of about Rs. 93 crore, this cyclotron is a major development from the existing K 130 room-temperature cyclotrons, whose magnets are capable of producing magnetic fields of only 18 kilogauss, says Amitava Sur, head of the VECC's Research and Development, Cryogenics.
Scientists working on the superconducting magnet, set up recently, aim at energising it further to produce a magnetic field of 55 kilogauss.
Most of its components have been fabricated in the country.
To achieve high magnetic fields the energising coils, through which 550 amperes of current flows, remain at minus 269 degrees Celsius with about 300 litres of liquid helium in a special vessel, cryostat.
