儀器簡介：
Hemispherical Electron Energy Analyser，Surface Science Products
技術參數：
RESOLVE ANALYSER
半徑: 120mm
反轉角度: 180 deg.
透鏡型號: Multi-element high transmission
入口狹縫: 6 sets positioned at entrance to hemispheres， used to vary analysed area
at the sample (also one factor determining energy resolution)
5x10mm 2.5x10mm 1x10mm 5mm? 2.5mm? 1mm?
( alternative slits / aperture sizes by special request )
分析區域： at the sample is approximately the same as the input slit size， the lens
having nominal magnification of X 1
出口狹縫:
RESOLVE MCD5 has ‘Standard’ and ‘High’ resolution defining exit slit mechanism which
is independent of the entrance slits)
磁場屏蔽: Fully enclosed Mu-metal internal shielding of hemispheres and lens
真空框體: Stainless steel
