Students

  15. Marc Henneaux, a well-known string theorist. Invited by NSC to Taiwan • “I have been truly impressed by the excellence of the “Center for Academic Excellence on Cosmology and Particle Astrophysics” which, by combining expertise over a wide range of knowledge, is, in my opinion, one of the leading places in the world where research in this area is conducted.” • 我對「宇宙學與粒子天文物理學卓越中心」之卓越印象確實深刻。我個人以為，該中心結合廣泛之相關知識與人才，確實已成為宇宙學領域研究之世界級中心之一。

  16. Subproject No. 4 on OIR Astronomy The NTU-CFHT agreement already signed (7/2001) • Participate the WIRCAM Project of the CFHT. • Use CFHT/OIR to conduct the LSS survey to complement the SZ survey of the AMiBA. Subproject No. 5 on National Infrastructure • Making the link between education and research • Small-telescope research projects such as TAOS.

  17. CosPA-4Collaboration with Canada/France/Hawaii Telescope Corp. • CFHT has been the most successful large optical telescope, situating on the best site on Mauna Kea – we need CFHT/MegCam or CHFT/WIRCam to do AMiBA follow-up surveys. • Through CosPA-4, we have acquired 68 CFHT nights (in a six year period, 2003-2007) at our disposal －Agreement signed between NTU/CosPA & CFHT in 7/2001。 • We are sending people to actively participate the construction of the WIRCam.

  18. CPU/BPA/NRC Report versus CosPA • CosPA’s overall scientific objectives sit amazingly well on top of this important report. • Currently, there are many other projects around the world, with a scale similar to our CosPA project.Center for Cosmology, U. Chicago; Caltech; Kavli Institute for Particle Astrophysics and Cosmology, Stanford U.; Research Center for the Early Universe (RESCEU), U. Tokyo; etc.

  20. Laboratory Astrophysics Program • Join the FLASH Collaboration • SLAC – CosPA MoU • Collaboration with SRRC • Financial Support

  21. Join the FLASH Collaboration Motivation • The Mystery of UHECRs: • the energy spectrum between AGASA and HiRes with 25% difference.

  23. SLAC – CosPA MoU • IntroductionThis Memorandum of Understanding (MoU) between National Taiwan University Center for Academic Excellence on Cosmology and Particle Astrophysics (CosPA) and the Stanford Linear Accelerator Center (SLAC) is a collaborative agreement between scientists of the two institutions. • AgreementsGeneral Agreements Funding, AmendmentsSpecial Agreements Scope of Responsibility, Scientific Personnel, Statement of Work, Equipment Ownership, Publications, Intellectual Property

  24. Statement of Work • The collaborating institutions agree to work on subjects of common interest, exchange information, develop theories, experiments and equipment of value to their mutual interests in subjects of Particle Astrophysics and Cosmology. • Examples of Particle Astrophysics and Cosmology Research might include but not be limited to CosPA’s phase-in active participation of the GLAST project. • Collaborations between the two institutions on laboratory astrophysics experiments as well as the development (with additional institutions) of a dedicated Laboratory Astrophysics facility at SLAC using high energy, high intensity particle and photon beams. • Other projects might include joint sponsorship of symposia and workshops on Cosmology and Particle Astrophysics, and mutual visits of scholars at all levels.

  25. Collaboration with SRRC Precision Adaptive Beam Profile Monitor: R&D and Applications • Taiwan CosPA Team:W-Y. Pauchy Hwang, P.I.Guey-Lin Lin, Co-P.I.Chien-Wen Chen, Ph.D. studentFeng-Yin Chang, Ph.D. studentYu-Chung Chen, Ph.D. student Chih-Ching Chen, student • Synchrotron Radiation Research Center:Dr. Kuo-Tung HsuDr. Gao-Yu Hsiung

  26. Significance & Expected Outcome:We wish to come up with an adaptive and well-tested beam profile monitor based on the OTR method.Provided that we could test different fabricated foils in our BPM/OTR setting, it could help to strengthen our understanding of the OTR properties of these materials and it could also help us in selecting a better OTR foil in the next round of our efforts to improve the BPM/OTR technique. • The Need for Using SRRC Electron Beams:The 1.5 GeV electron beam at SRRC, before being injected into the storage ring, is the only “high-energy” electron beam available in Taiwan.Without the possibility of using the SRRC electron beam as our laboratory at home, any new instruments for the beam manipulations cannot be sufficiently tested and further improved and it would be less possible for us to launch a successful laboratory astrophysics program. • We just had one solid week at our disposal to test BPM.

  27. The Proposed Schedule:We hope that there will be electron beam times which we could employ regularly from November 2003 till July 2004 so that(1) We could experiment with foils of different materials in order to explore the OTR physics quantitatively.(2) We would like to improve the BPM design accordingly so that a best BPM/OTR could be the final product.(3) We could use our BPM/OTR system in its final version as a tool to manipulate the SRRC beam.

  28. Financial Support • CosPA-3 & CosPA-0 (up to 2004.3.31) • NSC Project: Selected Topics in Cosmology and Astrophysics(2003.8.1 – 2006.7.31) • Post-CosPA (2004.4 – 2008.3), pre-proposal just approved, detailed proposal due 9/15/2003.

  33. Prospects • With your support (especially from my old friend Pisin), we plan to make Lab Astro an important part of CosPA & IoAp/NTU. • We wish to become an important, integral, and eventually indispensable partner in the entire FLASH collaboration. • Through the Lab Astro program, we wish to train our young talents as the future breed of laboratory astrophysicists.

  34. Acknowledgements • I, on behalf of the Taiwan CosPA team, wish to express the gratitude to Pisin for initiating our E165 participations and to Pisen and Johnny for supervisions of our hard-working students. • I wish to also thank Guey-Lin for his Co-P.I. roles together with his unqualified support. We welcome all of you to Taipei for our next collaboration meeting -- tentatively January 2004.
