    What’s a country to do if the international milieu, or one’s own self-constrained nature, prevents physical explosive tests. You do the next best thing to actual testing. Like, get yourself a Dual Axis Radiographic Hydrodynamic Test (DARHT) facility. Such a unit uses X-ray cameras to see just how a hydrodynamic shock to simulate implosion works — the process in effect of a fission bomb blowing, and study the integrity of this process in a fission bomb, or in the fission trigger of a fusion weapon. Technically this takes some doing. But, not if an all weather friend is supplying designs, expertise, and materials. As is the case with the DARHT unit the Pakistanis have succeeded in engineering and installing with, of course, China’s help and assistance, at Chaklala — headquarters, Strategic Plans Division — the Pakistani counterpart of the Indian Strategic Forces Command, the weapons directorate at BARC, and the nuclear cell in PMO rolled into one. It is expected to become operational by September-October this year. Boy, does that advantage Pakistan! And it shows just how serious the Pak Army is about that country’s nuclear security. Now turn your gaze homewards and what do we find? India has no DARHT, no inertial confinement fusion chamber, no nothing — not even computing speeds, but GOI still finds the situation hunky-dory! That same old — no need to test — canary continues to hold fort as S&T adviser to the PM — R Chidambaram, erstwhile chmn, AEC, the man singularly responsible for keeping the Indian boosted-fission and thermonuclear weapons sub-par, when he should have been the first person Modi ought to have unceremoniously dumped! This state of affairs about sums up the situation India is in today. India is forced to rely over much on Agni-5 (and technologies), a damned accurate missile at extreme range. The case made in govt circles no doubt prompted by this same Chidambaram is that, high accuracy means India can field just this one low yield but only proven warhead/weapon in our arsenal — the 20KT fission, and that this is more than adequate for the country’s strategic deterrence purposes! And to think the incoming Chinese DF-21mod2s will have a one megaton warhead, and nothing less than a fully performing 500 KT warhead. One is compelled to bury one’s head in a pillow, and moan. In the past, I called India’s approach “nuclear amateurism”. It is actually much worse, it is “nuclear fatalism”.

    India has been working on its own DAHRT facility since the 80's for three dimensional interior sub critical implosion testing , our single axis multi frame hydro dynamic testing facility was completed by 2008 dual axis would take another 6 to 7 years to come up but , for a full dual-axis, multi frame hydrodynamic test . The full-scale mock ups of nuclear primaries will start then . Our dual axis multi frame can take multiple sequential radiographs along the various axis .
    In BARC theoretical studies of materials at arbitrary temperatures and matter densities have been pursued to support the experimental groups on laser-matter interaction on various substances with plutonium type properties , shock data bank is being created , experiments to reproduce the total energies obtained by first principles calculations for various structures and compressions useful for large scale molecular dynamics (MD) simulations – including high pressure melting studies by 2-phase method, shock simulation on plutonium type material.

    India has multiple groups which have developed computational codes for testing the Hydrodynamic phenomena . The Hydro dynamic motion of the capsule is also coupled to other processes like radiative transfer, particle (n, γ, a) transport etc .

    BARC has developed robust numerical hydrodynamic algorithms, databases like Equation Of State (EOS), radiative opacity, particle interaction cross-sections and material properties for extensive simulation of the hydro dynamic phenomena in critical testing of our implosion device.
    Suffice to say we are making facilities for extensive testing of the plutonium pit under implosion pressure for very very high densities on the pit.

    We can simulate the implosion of the bomb in sub critical assembly on all the axis . We can and have sampled multi million atoms in shock simulation with our 128 node machine at BARC .

    KALI as I have already mentioned in this forum is a Virtual Cathode Oscillator (VIRCATOR) and can also be used as a generator for Flash X-rays which allow for an ultra-fast motion picture to be constructed showing the details of the implosion of the pit and its behavior under hydro dynamic condition.
    KALI in 2001 generated 1 MeV electron energy, 50-100 ns pulse time and by now they would have increased the electron energy and reduced the pulse time to few nano seconds for extremely efficent operation.
    KALI was created for simulation you know what

    Pakistan doesn't have the scientific or technical talent for making a DAHRT type facility it must have been given by their sugar daddy . Pakistan capability for testing an implosion device is akin to a donkey solving non linear differential equation unless China has helped . Since these fools started making U235 based gun type devices and realized they are fucking running out of uranium so the morons sifted to plutonium device which they might not have tested , China might have given them the codes and made them a cheap DAHRT type facility with limited electron energy to keep their Paki concubines happy .

    I believe a megaton weapon is only effective if used as an H-EMP weapon. For a surface detonation, MIRV is a much better option.
    Can this type of facility help in Neutron bomb development?

    For once I thought I read that paki fart up.
