Explosively driven helical flux compression generators or EHFCG have strategic role towards realisation of high power microwave generation ( especially compact sized EMP weapons easily delivered by aerial bombs PGMs or missiles ).

The picture below is very old and AFAIK only picture available of any component in relation to indian work on EFCG based technology.

The above picture is of a laboratory specimen of a helical FCG coil. In experiments with the above efficiency >= .75 was achieved.

Follow on experiments with improved design allowed a final output of 450ka with a seed current of only 4.3ka. at that time that is early 2000 it was the highest current gain ever achieved from HFCG experiments in India.
The high current pulse is then converted into high voltage pulse to drive a VIRCATOR to generate HPMW pulses strong enough to fry even hardened electronics etc.

Above is the block diagram of the timing circuit of seed current in stator and high explosive in armature and triggering of the diagnostics.

The EO pods are missing , looks like it was removed due to non availability of ATGMs and to save on maintenance costs etc

Should come back once HELINA and SANT becomes available

EO pods are required for the cannon too (for look down shoot down capability); but I guess they're not using that either!!

All I will say is ( to the best or worse of my knowledge as the case may be :biggrin2: )

Those who have knowledge of nuclear devices will know the significance of these laboratory specimens.

Both of these laboratory devices in the pictures are related to civilian applications which otherwise won't have been available in public domain.

However they also signify dual use technology

I will give hints note these words
1st picture spark gap trigger unit
2nd picture exploding foil

And the biggest hint

US nuclear weapons during WW2 used spark gap triggers , including India's first device.

US latest nuclear weapons use exploding foil deton.... commonly known as slapper deton....

So what conclusion can we arrive at vis a vis the triggering tech being used by India's present generation of nukes by noting the tech being used for civilian applications ?
Hum kisi se kum nahi :biggrin2:

Fun fact
The porkies tried to smuggle spark gap triggers ( krytrons ) used in kidney stone breaking medical devices for use in their high voltage triggers via a South African jew , but got caught. Later they went crying to the Chinese who gave them the tech.

Spark gap triggers are unsafe , and prone to accidents if kept on beyond a certain time frame.
Safest ones is exploding foil slapper deton.... and next best is exploding bridgewire deton....

why dont you start a blog of yours? the info you post is treasure trove collected from very open source but very distributed and difficult to find publications.. we may have quality alternative to livefist

I found the drdo slapper detonators used in the nukes and other applications

DRDO manufacturers 2 types of slapper detonators

1. Ceramic based
2. PCB based

These detonators are used for very precise detonation of the multiple explosive lens surrounding the nuclear core in a simultaneous manner for supersonic compression along the geometric axis.

Timing accuracies > 10 nanoseconds is possible using the above slapper detonators and with the lowest possible jitter.

These are especially required if one has nukes onboard submarines etc due to the over riding safety factor.

yawn... where is the wide angle hud? they were supposed to researching / developing that for some time.

DRDO develops quick response mobile facility for nuclear incidents

With threat perception of terrorists using weapons of mass destruction increasing, Defence Research and Development Organisation (DRDO) has developed a mobile facility to help provide immediate relief in case of any attack involving radioactive material.


The key equipment in the facility include a whole body radiation counter, storage system for containment of radioactive waste and provision for preliminary decontamination of the affected areas.


Whole body radiation counters are generally large and expensive devices consisting of massive high density radiation shields and sophisticated instrumentation. The new facility helps to avoid the handicap and at the same time provide a quick assessment of the nature of the radiation contamination and its extent. The facility offers the possibility of containerised transportation by any mode, while providing high resolution analysis of the contaminants.

A truck-mounted prototype was on display at the 'Pride of India' expo set up as part of the 106th session of the Indian Science Congress, which is underway here at Lovely Professional University. It was one of the major attractions at the expo, with children and adults, who are attending the conference, making a beeline and clambering up a steel ladder put up at the rear of the truck to have a glimpse of the facility.


Speaking to India Science Wire, Director General (Life Sciences), DRDO, Dr. A.K.Singh,said it takes just about 15 minutes to measure the radioactivity concentration per person and is a field-compatible standalone system.


The DRDO, he said, was also working, among other things, on developing low-cost polyhouses to help improve crop quality and productivity in border and other remote areas as part of an exercise to provide better supply of fresh vegetables, fruits and other food articles for army and paramilitary forces deployed in those areas, besides improving the socio-economic condition of the local population,


"Polyhouses cost about Rs 2-3 lakhs and are based on aluminium and other materials. Our aim is to use bamboo and other locally available material and bring down the costs to Rs 25,000-30,000. We are working to develop polyhouses of different sizes to cater to needs at individual, family and community levels," he added.


Noting that the main agenda of the life sciences division of DRDO was to develop life support technologies to improve combat efficiency, he said DRDO scientists have designed a state of the art backpack with a capacity of 90 kg with a facility to even stow away a rifle. “Indo-Tibetan Border Force has tried it out and they were happy with it”.


Among other things, special types of gauzes and gels have been developed to handle bleeding injuries better and have been tested out by the All India Institute of Medical Sciences “Our goal is to enhance health and well-being of the soldiers even in extremes of environmental and operational conditions, strengthen man-machine interface through human factors engineering, and boost the moral and motivation of troops”.

Asked about the problems that have been found with regards to the biodigesters that were developed by DRDO and were used by railways and other agencies, he said that corrective measures are being taken. "The problem was not with the technology. It had to do with their implementation. For instance, the working of the biodigesters depended upon the kind of bacterial cultures that were used and their quantity. The norms were not been followed properly. In many cases, there was overloading of the system. We are in touch with user agencies to ensure that correct procedures are followed," he said.

India Develops Advanced Laser Pods to Boost Fighter Jet's Attack Skills - Source

Indian scientists P. Suresh Kumar, N.N.S.S.R.K. Prasad and K. Senthil Kumar, who developed the system indigenously evaluated the performance of the LDP and found that the achieved average positioning accuracy in terms of azimuth and elevation computation for static and moving ground targets was +/- 2.3 metres. It met all the requirements needed to test the air-to-ground weapons in a flight simulator.

I read this earlier and wasn't sure if it's fake or real news.
This completely came out of the left field. Had no idea that DRDO was working on an LDP.
The way the article is written (referring to Lockheed Martin) sounds amateurish; but the scientist names are genuine!
Will wait for another source to corroborate.

No
The picture you posted is of siva targeting pod , it is used to scan, locate and accurately localise hostile EM emitters like radars etc, used in conjunction with anti radiation missiles (ARM) for DEAD/SEAD missions

Two types of semi-mobile electro optical tracking systems ( EOTS )

One on the left is a advanced long range system

Mainly used to track missiles etc optically during test firings etc

Varients of the same will also be installed in the 2 MRIS ships presently under construction.
