WEYMA02 India-based Neutrino Observatory - Present Status simulation, electron, target, controls 290
 
  • V. M. Datar
    BARC, Mumbai
  The current status of the India based Neutrino Observatory (INO) project is summarized. The two major physics goals are (a) unambiguous demonstration of neutrino oscillation and a more precise measurement of the associated neutrino parameters and (b) to search for matter effects in neutrino oscillation, using the charge identification capability of the magnetized iron calorimeter, which would help determine the signs of one pair of mass differences. The status of the 1 m3 prototype iron calorimetric detector, the design of the 50 kton magnet, the experience with resistive plate chambers used for tracking the charged particles produced in neutrino-iron interactions and the planned electronics and data acquisition system will be presented.

  A high power proton accelerator project, Proton Engineering Frontier Project (PEFP), as one of the 21C Frontier Projects conducted by Korean Government, has goals to develop a 100MeV high current proton linear accelerator, its beam utilization and industrial applications. As the front end of the 100MeV accelerator, a 20MeV linear accelerator consisted of a 50 keV proton injector, a 3 MeV RFQ, a 20 MeV DTL, was completed and tested. The rest part of the accelerator and various beam lines for beam utilizations are under construction, and also a site preparation and construction works are under progresses in cooperation with Gyeongju city. In parallel proton beam utilization and accelerator application technologies are extensively studied and under development. In this paper the status and the future plan of the project including test results of the 20MeV accelerator, site preparation and construction works, and development of proton beam utilization and user program will be presented in detail.

  We are now operating a web-based monitoring system of PAL control system with MAC Power PC. In order to expand the IOC’s web-based monitoring system, we are trying to use the X86/Linux platform. With the experience which we got in developing the web-based monitoring of EPICS-IOC based on MAC Power PC, a web-based monitoring system with an X86 Intel PC based on a new concept has been developed for lower costs, easier access and use. Its operating system employs Linux Fedora Cor·104. In order to drive the web-based monitoring system, EPICS Base 3.14.8 and MySQL 4.0 have been installed in the Linux Fedora Core 4. Archive engine with C language and EPICS channel access library are programmed to store the data. As a result of using the web-based monitoring system based on the X86 Intel PC, we have achieved its easier access and use, more convenient maintenance. Performance of the web-based monitoring system with an X86 Intel PC will be discussed.

  A 20 MeV proton accelerator has been developed and tested at Proton Engineering Frontier Project (PEFP) as a front-end part of the 100 MeV accelerator. The initial test results showed that more stable rf operation was necessary to investigate the machine characteristics more deeply. A LLRF control system using commercially available digital board was newly developed and tested for this purpose. The goals of the rf control for 20 MeV accelerator are to achieve errors within 1 % in amplitude and 1 degree in phase against external perturbations such as the change of resonant frequency, fluctuation of klystron power supply voltage and also beam loading. In addition, the PEFP 20 MeV DTL has unique characteristics that single klystron drives four tanks simultaneously. In this paper, the initial test results of the rf system with digital controller are presented and its control characteristics are discussed.

  The AMS technology and their applications have been developed at Peking University, China Institute of Atomic Energy and Chinese Academy of Sciences since 1980s’. In this presentation, the AMS facilities in China are described and the applications mainly in the field of archaeology are presented. Interesting results about the establishment of Chronology frame of Xia-Shang-Zhou dynasties based on cultural remains at Longshan, Er-li-tou. Xinzha and Tianma-Qucun Site etc. are given as examples. More then one hundred samples of oracle bone were studied for archaeological radio-carbon dating with the AMS facility at Peking University. AMS applications in the fields of geosciences, environmental and biomedical sciences are introduced as well.

  In the J-PARC site, the inflastructure for the whole site measurement is planned for the global alignment of the accelerator components. For the neutrino experiments, the J-PARC main ring must be directed to the SUPER-KAMIOKANDE exactly. The global measurements from the Kamioka site to the J-PARC site is carried out by using GPS system on the gound level. Several measurement holes, in order to tranport the coodinates from the ground level into the accelerator floor level directly, are prepared around the J-PARC accelerator complex. The magnet alignment method for the J-PARC main ring are reported with the present alignment status.

  Since the foundation of ACCEL Instruments, Asia-Pacific has been an important market for RF, magnet and x-ray beam line devices. For the RF activities, pioneering work was done for JAERI, where complete superconducting rf modules where designed, built, tested and delivered. An important step for industrialisation of superconducting rf modules was done, when NSRRC decided in 2000 as the first Light Source, to contract turn key superconducting 500 MHz modules of the Cornell design to ACCEL. Similar modules have been delivered in the meantime to CLS, Cornell and DLS and three more will be delivered to SSRF in Shanghai next year. Peking University is planning to use a Rossendorf design superconducting rf module housing two 1.3 GHz TESLA cavities for the operation of their FEL project. On the normalconducting rf systems, a complete 3 GHz, 100 MeV linac has been delivered to ASP together with the 500 MHz booster cavities and the LLRF system. Booster cavities and LLRF system will be also delivered for SSRF. For SOREQ in Israel, ACCEL is developing a complete superconducting 40 MeV proton/detueron linac. The first stage of this linac is currently under delivery and installation.
