四袋電子束蒸發器
儀器簡介：
The e-flux Mini E-Beam Evaporator is an UHV evaporator for small and medium quantities of almost any material in the temperature
range of 400K to 3100K. Evaporation is possible either directly from evaporant in rod form (?26mm)
or out of a crucible. An integrated flux monitor allows maximum deposition control.
Highly efficient watercooling ensures negligible outgassing during operation.
The e-flux electron beam evaporator is very compact and mounted on a CF-40 flange (2.75"OD).
很容易安裝在已經有的 UHV 或 MBE系統上。
主要應用是：表面科學，薄膜沉積，薄膜摻雜
主要蒸發材料： Mo, Ta, W, Au, Ag, Pt, Al, Cu, Ni, Ti, C, Si, Cr

主要特點：
特點:
1,發射電流穩定性:
The emission current stabilizer is a closed loop control to keep the emission
current constant automatically with rod melting down or decrease of crucible content
2,LED提示棒材位置
An LED alerts when the evaporation rod has to be fed. Threshold can be customer set.
3,可輸入需要的發射電流
The emission current can now be set directly on a linear scale for easy reproduction.
4,離子阱選項
The ion trap option allows to deflect all charged particles out of the beam.
