Beschreibung
Zusammenfassung:	The invention relates to a device (100) for identifying a smoke event (SE) in an electron beam melting device (10). In order to better predict or be able to automatically identify smoke event recommendations, the device has a current measuring device (150) configured to detect a ground current (IG) and an analysis unit (160) configured to identify a smoke event (SE) by analyzing the ground current (IG). Furthermore, the invention relates to the electron beam melting device (10) and a method for operating the device. 本发明涉及一种用于在电子束熔炼设备(10)中识别烟雾事件(SE)的装置(100)。为了更好地预测或者能够自动化地识别烟雾事件建议，所述装置具有构造用于检测接地电流(IG)的电流测量装置(150)和构造用于通过分析接地电流(IG)识别烟雾事件(SE)的分析单元(160)。此外，本发明涉及一种电子束熔炼设备(10)以及一种用于运行这种设备的方法。
