S-band BPM in ATF2
Kyungpook

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)

OECD-GSF
• 기술협력국 소관 (미주기술협력과) – KISTEP 과제
– 2000년부터 이정일, 오선근, 손동철 활동
– LC에 관한 CGHEP 활동 및 보고서 (2002년)
– LC에 관하여 정부/STEPI 측에서는 계속 자료 수집 등 전문위원들의
지속적인 활동 요망
– 2003.12-2004.1: 기초연구국에 검토 협조 요청
– 2004년 8월: 2003년도 활동 보고
• 기초연구국 소관 (기초연구지원과)
– 2003년 12월-2004년 1월에 OECD 과학기술장관회의 준비 차 LC에
대한 보고 문건 작성 제출 (손동철) 및 과기부 검토
• 현황 및 참여 방안 (예시 제출)
• 기술협력국에 검토
– 2004년 1월 OECD 과기장관회의에 과기부 기초인력국장 참석:– 발
언 및 선언문 채택 참여 (정부 입장은 참여 쪽으로 검토되었음.)
29
Funding Agencies Meeting
• 2004년 8월 일본 Yamauchi 교수(문과성/KEK)로부터 편지
• 영국 PPARC가 주관하여 4차까지 진행한 “Funding
Agencies Meeting for LC” 의 한국 측 참여를 위원장 (Ian
Halliday)으로부터 희망한다는 내용
• 기초연구국 기초연구지원과에 참여 권유 및 관련 자료 제출
및 발언할 내용 검토 (손동철)
• 2004년 9월 16~17일 CERN 회의에 참석(기초연구지원과
장, 손동철), 과장 한국측 입장 발표
– LC 사업에 대하여 한국은 적극 참여를 희망
– (회의록, 공식회의록, 미국측 회의록 내용 참조)
30
정부의 후속 조치
• 2004년 9월 FALC회의 참여 동안 기초연구지원과와 관련 후속 조치 및
추진 방안 협의
– 우선 포항가속기 연구소의 인프라를 이용하는 방안을 검토 요구 (9월 23일)
– 포항가속기연구소의 향후발전계획 가속기 관련 국제협력 부분에 LC에 관한 계획을
언급토록 정부에서 요구 (손동철 작성 제출, 10월 4일)
– 그러나 10월 13일 정부에서 ILC사업 추진 방침을 내부 결정
• 주관 국가 내지 주관 컨소시엄으로서의 참여 방안 제출 요구
• 자료 제출 (손동철 10월 14일, 고인수 수정)
– 10월 16일 정부의 조직개편의 기초연구지원과 업무분장에
• 국제선형가속기 국제공동연구의 추진 명시
• 2005년 기초연구국 기획과제로 국제선형가속기사업 참여 방안 연구 수행
•
•
•
•
•
이후 2007년까지 FALC Resources Group 회의 (국내에서 2회 개최)에 정부 사
무관 참석
2005년 ILC-GDE Common Fund MoU 서명을 한국 CHEP이 대신하며, 관련 비
용을 추가로 CHEP예산에 반영토록 내부 합의
2007년 이후 정부 입장 변화???
2006년 이후 ILC-GDE Common Fund의 참여분을 경북대 고에너지물리연구
소가 지불하였음. (초기 1/6, SRC종료 이후에는 1/15~20 정도)
현재 새로운 협약 체결을 검토하자는 요청을 받고 있음.  해결해야 할 문제
