Marc Henneaux, a well-known string theorist. Invited by NSC to TaiwanI 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.
Subproject No. 4 on OIR AstronomyThe 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 InfrastructureMaking the link between education and researchSmall-telescope research projects such as TAOS.
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 7/2001We are sending people to actively participate the construction of the WIRCam.
CPU/BPA/NRC Report versus CosPACosPAs 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.

SLAC CosPA MoUIntroduction This 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.
Agreements General Agreements Funding, Amendments Special Agreements Scope of Responsibility, Scientific Personnel, Statement of Work, Equipment Ownership, Publications, Intellectual Property
Statement of WorkThe 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 CosPAs 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.
Collaboration with SRRCPrecision Adaptive Beam Profile Monitor: R&D and ApplicationsTaiwan CosPA Team: W-Y. Pauchy Hwang, P.I. Guey-Lin Lin, Co-P.I.

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.
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.
