我们报道了一种简单可靠的用于液氦场电离的钨尖刻蚀技术。这种尖端通常在400 - 600 V的电压下产生1 - 100 pA的正电流,并且工作数月没有退化。讨论了成功使用这些技巧的一些建议。
We report a simple and reliable technique of etching tungsten tips to be used for field ionization of liquid helium. Such tips routinely yielded a positive current of 1 - 100 pA at a voltage of only 400 - 600 V and worked without degradation for many months. Some suggestions for the successful use of such tips are discussed.
