Recently found two Super Conducting Neobium Cell Cavities being made using Electron Beam Welding for a RRCAT Particle Accelerator. Here is a 650MHz cavity :

And the 9-cell cavity with combined capacity of 1.3GHz :

This is the perplexing piece of hardware. Why do we have it ? The current particle accelerators in the country are decades old. Why are we making new cavities that were never a part of the original design ?

The most powerful accelerator we have today is the "Indus 2" with a Synchrotron power level of 2.5 GeV. There is a new still proposed accelerator
called the International Linear Collider (ILC), which is a collaboration between USA, Europe & Japan, also uses a 1.3 GHz cavity.

The ILC is far more powerful than any present RRCAT accelerator. The ILC will begin operations at 500 GeV, then it will be ramped up to 1 TeV.
So how come we are making the same hardware as them ? The only logical explanation is that we might have a new accelerator under construction. The last one was built 15 years ago, its about time.
When Dr. Kalam was the president he visited Fermilabs in the USA. Where the then director of Fermilabs insisted on India's (in particular RRCAT's) participation in the ILC. That never happened though. RRCAT also participated heavily in CERN's Large Hadron Collider.
It seems to be a further development from existing 500 Mhz cavity:

Next, a major effort has been launched on the development of superconducting radio frequency (SCRF) cavities required for the development of high energy proton accelerators for spallation neutron source and accelerator driven system.
A large facility is being set up for SCRF cavity fabrication, processing, assembly and testing. Recently developed prototype 1.3 GHz single-cell niobium SCRF cavities have shown excellent performance providing acceleration gradient exceeding 35 MV/m with a quality factor of 2x1010 at 2 K.
Other highlights on the technological accomplishments include indigenous development of helium liquefier, high power solid state RF amplifiers as an import substitute for klystron source, and development of nonevaporable getter coatings to achieve vacuum better than 10-11 mbar. In this talk, an overview of the accelerator activities at RRCAT will be presented
@Nilgiri , I still have a reservation to consider it as best, in the last Armenian conflict the Azeri Harpy literally took out the AD systems one by one . I am not sure how successful it will be on eastern front .
The second point is can we integrate thme in our existing systems , I think its integration with Barak 8 will be deadly and require a lot more resources from opponents to counter

The behemoth of all diesel engines designed and developed in India is now ready. The Prototype is tested for full power using the turbocharger made by GTRE.
The engine is probably one of the most important components of any moving vehicle including the main battle tanks (MBT). These powerplants aka engines should produce the required amount of power and torque to move a 50-60 tonne battle tank in different types of terrains and scenarios. To move these tanks, heavy capacity diesel engines are used which produce a lot of power and torque.
