R&D Efforts for ILC in KoreaR&D Efforts for ILC in Korea


Some history for ILCSome history for ILC A Planning Team formed at CHEP (March 2004) Korean ILC Workshops (4 times + 3 mini-workshops) PAL ILC Task Force (Jan 2005) formed Strategic Plannings for ILC (three times) ILC-Asia MoU (Aug 2005)

CHEP, PAL, KEK, IHEP, TIFR, CAT, IUAC ILC-Common Fund MoU (Oct. 2006) Held Several international conferences and workshops Research Projects;

Int. Coop. Project (P.I.-H. Park) for Physics and Detectors SRC Projects (Accelerator & Detectors)

Several Committee Activities: ICFA, ILCSC, ITRP, Parameter, LCWS–WG Coordinators

1. LCWS 2002 (Jeju)

2. 8th ACFA LCWS (Daegu 2005)

3. Committees: ITRP(Pohang 2004) and ILCSC, ICFA, FALC-RG during ICFA Seminar (Daegu 2005)

4. ILCSC, ICFA, FALC-RG during LP07 (Daegu )

5. Ecloud’07 (Daegu)

6. And this workshop

S-band BPM in ATF2 S-band BPM in ATF2 KyungpookKyungpook

What for with this BPM(beam position monitor) ? To control beam orbit at final focus beam line in ATF2 To do BBA(beam-based alignment) with 1 mm at final focus

beam line in ATF2 (BPM resolution of a few hundreds nm should be satisfied.)

Requirements for the BPM Dynamic range ; a few mm Diameter of beam tube ; 40 mm Signal decay time ; 35~ 80 ns (where, f= 2878 MHz,

QL = 650~1800, longer decay time will is preferred for the electronics)
