본문통과대10Be리자재가속기질보계(CAMS)고능단속류전수진행모의계산,학정료10Be리자속류전수적우화설계。설계안장료측량9 Be속류적법랍제통、능량흡수막(SiN막)장치、ΔE-Eres기체탐측기등,결과표명,개진후적CAMS가진행10 Be측량,10 Be측량총전수효솔약위2%,측량본저약위4×10-14。
Firstly ion optics calculations for the transport of 10Be were performed for the high energy system .Then a new Faraday cup was installed to measure high energy 9Be current and holder for silicon nitride foil (SiN-foil) was mounted .For the detection the Si-detector at the end of the beam line was replaced with a high resolution ΔE-Eres gas ionization chamber .The results show that the overall transmission efficency is about 2% and the 10 Be background level is limited to 4 × 10-14 .
