من هم المستهلكون الرئيسيون للهيليوم؟

Who exactly are the primary consumers of helium? Could you elaborate on the industries or applications that have a significant demand for this element? I'm particularly interested in understanding the role of helium in high-tech sectors like aerospace and semiconductors. Additionally, are there any emerging markets or trends that are driving the consumption of helium in recent years? I'd appreciate it if you could provide some insights into this matter.
