Highlights

A unique facility in the country for prompt
\r\ngamma coincidence spectroscopy using
\r\nthermal neutron beam



8/2020

we have studied the phenomenon of neutrino spin-flavor oscillations in the Sun for neutrinos having sufficiently large magnetic moments ~ 10 ^-11 μ B. We have constructed two models for solar magnetic field based on the current bounds on the magnetic field in different regions of the Sun. In the first model, one can have large magnetic field in the solar core and it tapers off with distance from the center. In the second model, we have a large magnetic field in the RZ which becomes negligible in the core region and in addition there is a CZ magnetic field. We have also obtained a novel parametrization for the electron density profile in the Sun, which provides a better approximation compared to the usual exponential parametrization.

Understanding the nuclear scission process from alpha particle accompanied HI fission



3/2018

For the synthesis of super heavy elements, it is proposed to fuse neutron rich radioactive ion beam (RIB) with heavy targets. It is now well known that the reaction mechanisms using RIB having small particle separation energy can be simulated by using weakly bound stable projectiles having low breakup threshold. In case of weakly bound stable projectiles, the study of fission rocess following compound nucleus formation becomes complicated as it gets mixed up with various breakup or transfer induced fission channels.

The Pelletron-Linac facility, set up as a joint project between NPD-BARC and the Tata Institute of Fundamental Research, has been a major centre for the heavy ion accelerator based research and applications in India. NPD (Nuclear Physics Division) operates, maintains and upgrades the BARC-TIFR Pelletron Accelerator. The Pelletron accelerator has been delivering wide variety of ion beams round-the-clock ever since it’s commissioning in December 30, 1988.

The high current irradiation set up at 6 meter level was developed and utilized for radioisotope production since September 18, 2004 and subsequently customized
\r\nto perform secondary neutron production in June 01, 2013 and more recently for radiopharmaceutical and ther applications. Several applications require the neutron yield to be as high as 107-109 n/s. This facility also provides neutron yield in the range of 107-108 n/s via protons bombarding Lithium or Beryllium targets with few MeV and few hundreds of nA beam current. Allows irradiation of solid as well as liquid samples. This facility is also being used for radio pharmaceutical and tracer applications.

Low flux of protons in the range of 103 to 108 particles/cm2/s in air is required for radiological applications and qualification of space based electronic devices. This set up has been utilized since November 01, 2007 and undergone various up-gradations. The set up is further customized in January 9, 2018 for conducting induced-mutation studies in grains, successfully. Induced-mutation in Rice and Wheat using low flux proton beam is being pursued by NA&BTD, BARC. The set up is tailored as per experimental requirements. The testing of space bound electronic devices is extensively performed by ISRO. This set up is continuously modified as per their typical requirements.
