Ragu, tapi ga ngasih alesan?
Biar ane tebak, alasannya karena cinak gak mungkin bisa, krn mereka bisanya bikin produk kw.
Begini doank kualitas argument nya?
Itu nama institusinya Wuhan National High Magnetib Field Center didirikan di tahun 2005, awalnya..... Seperti Reaktor Nuklir indonesia di Serpong, tujuannya untuk penelitian .... CMIIW
Wuhan National High Magnetic Field Center（WHMFC）
The Wuhan High Magnetic Field Center was established in 2005 for the development of pulsed magnets and their application to scientific research. Presently, the main task of the center is the development of a pulsed high magnetic field facility, which is one of the twelve National Major Science and Technology Infrastructure Projects in the “National Eleventh Five-year Plan” funded by the Chinese National Development and Reformation Committee.
At the WHMFC, the objective of the pulsed magnet development program is to generate pulsed magnetic fields in the range of 50 to 80 T. The following pulsed magnets were initially conceived: 1) 50–80 T monolithic magnets energized by one or a few modules of the 1 MJ capacitor bank, 2) a 50 T / 100 ms flat-top long pulse magnet energized by the 100 MJ / 100 MVA pulse generator, 3) a 60 T / 200 ms long pulse magnet energized by the 12 MJ capacitor bank, and 4) an 80 T dual coil system energized by two capacitor bank modules. In addition, a 16 T PPMS and a 7 T SQUID-VSM system were acquired.
After four years of construction, pulsed magnetic fields in the range of 50-70 T, the PPMS and SQUID-VSM are now available for experiments including electrical transport, magnetization, electron spin resonance and magneto-optics. With a view to further development of the laboratory, work on a 40 T long pulse magnet driven by lead acid battery units and the acquisition of a 400 MHz NMR spectrometer are in progress.
The pulsed power supply system at the WHMFC is designed to energize a series of high magnetic field coils. It is composed of the following three different types of power supplies: a 14.8 MJ / 25 kV capacitor bank, a 100 MVA / 185 MJ inertial energy storage generator system and a lead-acid batteries bank.
The capacitor bank consists of twelve modules of 1 MJ / 3.2 mF / 25 kV / 45 kA sub-banks, two modules of 0.8 MJ / 2.56 mF / 25 kV / 60 kA sub-banks and one module of 1.2 MJ / 3.84 mF / 25 kV / 60 kA. Each capacitor module is equipped with a charging unit, capacitors, polarity changing switches, thyristor switch, the crowbar circuit and the protecting inductance to limit the short circuit current. These different capacitor bank modules can be connected separately to three different connectors installed in some of the measurement cells by means of the selectors in the power supply hall, in order to energize coaxial multi-coil systems with up to three separate sub-coils. The entire modular capacitor bank system was put into operation successfully in mid-2011. At present, the capacitor bank has been used to energize many pulsed magnets including an 83 T dual coil magnet.

Sama seperti pusat riset lainnya di dunia yang menghasilkan teknologi baru yang bermanfaat untuk keperluan militer .... permasalahannya adalah terkadang orang2 awan dan orang2 yang menggantungkan hidupnya pada berita sering terjebak pada istilah teknis dan ilmiah yang melambungkan imajinasi liar mereka.
sama seperti kasus "The Large Hadron Collider | CERN" yang sampai dibuat filmnya ....
Mengenai "Wuhan National High Magnetic Field Center（WHMFC）" bisa main2 kesini dan baca2 mengenai aktivitas research mereka.
Memang terkadang disini orang awam itu kalau ketemu berita yang sensaional dan waww tanpa cek ricek langsung di copy dan diberi komentar aneh2 tanpa melihat apakah artikel itu benar atau ditulis sama wartawan bodrek .....
