	Precise, single shot measurement of the beam position with a sub-micrometer resolution is required for the next generation linear accelerators such as International Linear Collider (ILC) and X-ray Free Electron Laser (XFEL). As a pill-box cavity structure is sensitive to the transverse offset of the beam at the dipole-mode resonance, e.g., TM110-mode, a pill-box type cavity is a good candidate for the sub-micrometer beam position monitor (BPM). Test cavity BPM had been designed and tested in KEK successfully, and miscellaneous improvements for the final prototype fabrication and beam tests are performed in collaboration between KEK, SLAC and PAL. With the successful results of beam test in ATF, 41 cavity BPMs will be produced by PAL and installed in ATF2, which is an advanced beam-test line under construction as the extension of existing ATF for the beam studies on the final focus of the planned ILC program. Technical design considerations, fabrication and test results are described in this paper.

FRXMA03	Achievement of ATF and its Future Plans	837
	J. Urakawa KEK, Ibaraki
	The ATF (Accelerator Test Facility at KEK) International collaboration has been launched formally under the MoU (Memorandum of Understanding) from August 1, 2005, so as to maximally contribute to the world design and development efforts in the areas of particle sources, damping rings, beam focusing and beam instrumentation towards the International Linear Collider (ILC) project. I will give a talk on the recent achievement at ATF and its future plans, especially ATF2 project.
