  • Looking Back Over 27 Years of Grant-In-Aid Recidivism by Dr
    KAKENHI ESSAY SERIES No.14（Feb2009） Looking Back over 27 Years of Grant-in-Aid Recidivism By Dr. Atsuto Suzuki, Director General, High Energy Accelerator Research Organization (KEK) Looking back over the evolution of my research, I couldn’t have cut myself off from Grants-in-Aid even if I had tried. Among the results the program has yielded has been the ability to acquire budgets for well-equipped facilities and to pioneer new fields of research. My initial contact with the Grant-in-Aid Program took place when I moved from the University of Tokyo to the High Energy Accelerator Research Organization (KEK). Over a 27-year period from 1982 through 2008, I have in both the capacities as a principal and collaborating investigator received support every year from the program. I have listed below these many Grant-in-Aid supported projects. From FY 1982-1984: Specially Promoted Research, titled “Verification of Grand Unified Theory; Nucleon Decay Experiment, Using Water Cherenkov Detector” (Representative: Koshiba Masatoshi) This grant helped foster the Kamiokande (Kamioka nuclear decay) facility and its experiments. The objective of Kamiokande was to verify the Grand Unified Theory by detecting and elucidating the nucleon decay phenomenon. From FY 1985-1986: Basic Research (A), titled “Proton Decay Experiment” (Representative: Teruhiro Suda) This was the most discouraging period in the operation of Kamiokande, as great difficulty was being experienced in detecting nucleon decay and the future of the facility seemed bleak. Then, Dr. Koshiba detected the solar neutrino, so plans were initiated to retool the Kamiokande devices. From FY 1986-1987: Basic Research (A), titled “Observation of Solar Neutrinos” (Representative: Yoji Totsuka) Through a process of trial and error the Kamiokande facility was reconstructed.

I recognize several of them, not because they are famous actors or artists, but because I have seen them speak at conferences or, as in one particular case, worked closely with him. They were Professors Yifang Wang, Koichiro Nishikawa, Atsuto Suzuki, Kam-Biu Luk, Takaaki Kajita, Yoichiro Suzuki, and Art McDonald. All were being recognized for their work on understanding the properties of neutrinos—on prime-time television. As I said, it was an unusual sight. A mystery thirty years in the making The event that was being televised that evening was the award ceremony for the 2016 Breakthrough Prize in Fundamental Physics.

Tata Institute of Fundamental Research (TIFR) was established by the visionary scientist Dr. Homi J. Bhabha in 1945, and is one of the premier research institutions in India. It has been declared a National Centre of the Government of India for Nuclear Science and Mathematics. It carries out fundamental research in diverse areas: physics, chemistry, biology, mathematics, computer science and science education. It has doctoral programs in all these above disciplines, leading to Ph.D. degrees. TIFR aspires to be among the best scientific institutions in the world, and aims to train its students to become excellent researchers, comparable to the products of the best international universities. To achieve this aim, the structure of our curricula, our syllabi, examinations and research programmes have been so made that the students are exposed to the frontiers of knowledge in their respective disciplines, and are given hands-on exposure to advanced research. The TIFR graduate school has the advantage of being embedded in a vibrant research atmosphere, with state-of-the-art equipment and facilities. The academic programmes of TIFR fully utilises the research facilities, and expertise of the faculty members, most of whom are world experts in their respective subjects.

These theories predicted that protons and neutrons (i.e., nucleons) should decay with the lifetime of about 1028 to 1032 years. Several proton decay experiments began in the early 1980’s. One of them was the Kamiokande experiment.

  • Stuart J. Freedman
    Stuart Jay Freedman 1944–2012 A Biographical Memoir by R. G. Hamish Robertson ©2014 National Academy of Sciences. Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. STUART JAY FREEDMAN January 13, 1944–November 10, 2012 Elected to the NAS, 2001 Stuart J. Freedman was an experimental physicist with a broad sweep of talents and interests that centered on nuclear physics but also spanned particle physics, quantum mechanics, astrophysics, and cosmology. As a graduate student at the University of California, Berkeley, he carried out a crucial test of the Einstein-Podolsky- Rosen (EPR) argument that quantum mechanics was an incomplete theory; Stuart showed that EPR’s postulated local hidden variables did not explain experimental data, whereas quantum mechanics did. Stuart was an early and continuous leader in the search for neutrino oscilla- tions, and in the KamLAND project he determined which of several possible solutions the correct one was. He also was noted for several instances in which an incorrect By R. G. Hamish Robertson result with major implications was neutralized. Perhaps the most famous case involved the 17-keV neutrino. Stuart was born in Hollywood, CA—the son of David Freedman, an architect, and Anne (Sklar) Freedman—and attended schools in Beverlywood. By all accounts he was a strong student and a “normal” teenager, with a penchant for ruffling establishment feathers whenever possible. His occasional minor run-ins with the law and hilarious interactions with bureaucracies became the stuff of good stories later in life.

Summary of State of WPI Center Project Progress (write within two pages) Kavli IPMU is moving from the first phase of building the institute to the next phase of harvesting science. Even though the institute was launched from scratch, our impact factor is already comparable to world-leading institutes. Many of our observational and experimental activities have started to produce results after years of preparations. Science and Interdisciplinarity 352 (347) papers were published in refereed journals during the FY 2012 (Calendar Year 2012), with a steady increase over the past years (13, 111, 202, 236, 252 for FY 2007 to 2011, respectively). The impact factor based on cumulative record since the inception to March 2013 shows the strength of our scientific output: 12.6 citations per paper and 44 papers with more than 50 citations. This data is based on Web of Science by Thomson Reuters, and we specifically excluded a particular review paper which has a huge citation number.

The 80 participants included high-energy physicists, nuclear physicists, cosmic-ray physicists and astrophysicists. Both theorists and experimentalists were participated. This was the concluding workshop of a series that started in February, 1987. It was supported by a Grant-in-Aid for "Scientific Research on Priority Areas" by the Ministry of Education "Elementary-Particle Picture of the Universe", after having a few sporadic workshops held over the preceding few years. At that time there was a growing interest in interdisciplinary fields among particle physics and astrophysics: there were large activities searching for proton decay, as a decisive test for grand unification theories, which are closely related to our understanding of the baryon number generation in the universe.

  • 00. Icecube SAC Report 2015 Final.Pdf
    November 30, 2015 Report IceCube Science Advisory Committee Meeting Oct 19-20, 2015 Introduction The IceCube Science Advisory Committee met at the Wisconsin IceCube Particle Astrophysics Center on October 19-20, 2015. The members in attendance were Roger Blandford, Edward (Rocky) Kolb, Steven Ritz, Jennifer Thomas and Barry Barish (Chair). The agenda and a set of questions posed to the committee are in Attachment A & B. A special focus of this meeting was the NSF solicitation for the Management and Operation of the IceCube Neutrino Observatory. The WIPAC proposal has been submitted and the committee was asked to review the written proposal and presentations to the SAC, in anticipation of a review meeting of the proposal that is expected in the coming months. Below we summarize the main conclusions and recommendations from the SAC committee. General Remarks Neutrino physics and astrophysics continues to be a very rewarding scientific endeavor, in spite of the enormous experimental challenges. The field has recently received a lot of attention, especially with the Nobel Prize to Art McDonald and Takaaki Kajita for neutrino oscillations, the award of the Breakthrough Prize to Yifang Wang, Kam-Bui Luk, Art MacDonald, Koichuro Nishikawa, Takaaki Kajita, Atsuto Suzuki, Yoichuri Suzuki, the commitment by DoE to the field at Fermilab, and the observation of cosmic neutrinos by IceCube. Much discovery space is still available for future neutrino research, especially at high energies. IceCube has published information on more than 50 cosmic events and this provides strong motivation for the future program on high energy neutrino astrophysics. There are several neutrino project underway or planned, and they promise to address many of the main questions and uncertainties in our present knowledge, including obtaining better oscillation parameters, addressing the hierarchy problem and observing CP violation for neutrinos.

    Detection techniques and investigation of different neutrino experiments Ankur Nath∗ and Ng. K. Francisy Department Of Physics, Tezpur University, Assam-784028, India (Dated: August 10, 2018) Neutrino physics is an experimentally driven field. So, we investigate the different detection techniques available in the literature and study the various neutrino oscillation experiments in a chronological manner. Our primary focus is on the construction and detection mechanisms of each experiment. Today, we know a lot about this mysterious ghostly particle by performing different experiments at different times with different neutrino sources viz. solar, atmospheric, reactor, accel- erators and high energy astrophysical; and they have contributed in the determination of neutrino parameters. Yet the problems are far from over. We need to determine more precise values of the already known parameters and unravel the completely unknown parameters. Some of the unknowns are absolute masses of neutrino, types of neutrino, mass hierarchy, octant degeneracy and existence of leptonic CP Phase(s). We analyse the neutrino experiments into the past, present and the fu- ture (or proposed). We include SNO, Kamiokande, K2K, MINOS, MINOS+, Chooz, NEMO and ICARUS in the past; while Borexino, Double Chooz, Super-K, T2K, IceCube, KamLAND, NOνA, RENO and Daya Bay in the present; and SNO+, Hyper-K, T2HK, JUNO, RENO-50, INO, DUNE, SuperNEMO, KM3NeT, P2O, LBNO and PINGU in the proposed experiments. We also discuss the necessities of upgrading the present ones to those of the proposed ones thereby summarizing the potentials of the future experiments. We conclude this paper with the current status of the neutrinos.
