Accelerator Facility for the Northeast

posted Sep 25, 2019, 7:04 PM by Department of Physics

  Title   Exploring frontier of science with the proposed accelerator facility for the Northeast
  Speaker  Dr Jiban Jyoti Das (Visiting Faculty at Physics, GU), National Superconducting Cyclotron Laboratory, Michigan State University, US
  Type Research Colloquium
  Date Thursday, 26 September, 2019
  Time 2:30 PM
  Venue Physics Gallery, GU

Abstract

A state of the art 5 MV Pelletron Accelerator Facility is proposed. The accelerator will have an Electron Cyclotron Resonance Ion Source at the High voltage terminal. This accelerator will be first of its kind in India and open up exploring new frontier of science. Examples will be given in accelerator Science, Applied Science and Basic Science. In basic science, the proposal for accurate measurements of thermonuclear reaction rates in stars will be discussed. As we know today, Quantum tunnelling lead to generation of energy and formation of elements in stars. The NE accelerator centre will create a laboratory environment close to interior of the stars thus making it possible to accurately measure the formation of the elements.


Biography

Dr Jiban Jyoti Das is an Applied Isotope Development Physicist at National Superconducting Cyclotron Laboratory, Michigan State University, USA. An alumnus of Cotton College, he did is MSc in Physics from IIT Kanpur in 1990. He obtained his PhD degree at Inter University Accelerator Centre (University of Delhi). Presently, Dr Das joined the Physics Department, GU as a Visiting Faculty for one year.

Apart from being a topper in both BSc and MSc, he received Best Scientist award at Nuclear Science Centre, New Delhi in 2005. He was a Postdoctoral Fellow at the Centre of Excellence for Stewardship Research in RIB studies, Oak Ridge National Laboratory, USA.

He was the first scientist in India to produce Rare Isotope Beams by a novel technique. He successfully implemented his innovative idea to produce Radioactive Ion Beam at IUAC, Delhi, with DST support. Recently Dr Das has achieved a new milestone by using accelerator at NSCL/FRIB. 

Refreshments will be served after the talk.

  Title   Global Climate Impact Study of VLS-PV installation in Deserts
  Speaker  Sangeeta Sinha, B R Amdebkar Bihar University, Muzaffarpur
  Type Research Colloquium
  Date Wednesday, 13 February, 2019
  Time 4:00 PM
  Venue Physics Gallery, GU

Abstract

Very Large Scale Solar Photovoltaic (VLS-PV) System installation in deserts is rather a matter of time only. However global climate changes have made it imperative to asses environmental impact of such installations, since land surface property has strong linkages with atmospheric circulations. The partitioning of the available energy at the surface between latent and sensible heat fluxes are bound to play an important role in the interactions between the earth surface and the atmosphere. The actual evapotranspiration, linked to the latent heat flux, is involved in both the water cycle and the energy balance at the surface. Large-scale synoptic patterns and mesoscale atmospheric structures determine the meteorological variables like the cloud cover, the surface radiation, the wind speed, the air temperature and humidity and, as a consequence, evapotranspiration (AET). In turn the AET and the surface turbulent fluxes act as boundary conditions influencing the characteristics of the atmosphere far above the surface in the so-called atmospheric boundary layer.

  Title   Science JUNCKtion
  Speaker  Dinesh Lahoti (See Biography)
  Type Pedagogic, Lec-Dem
  Date Thursday, 31 January, 2019
  Time 2:30 PM
  Venue Physics Gallery, GU

Abstract

In this hands-on session, we will explore and try to understand science from readily available materials. The talk will focus on science communication, importance of activity based exploration and questioning. In this regard, how the post graduate students can contribute will also be discussed.
