摘要：

A field emission apparatus operating at cryogenic temperatures was developed by using an Al-SUS explosion bonded metal composite to get a good thermal contact of the sample and the radiation shield with the liquid helium reservoir. With this apparatus, a tip sample temperature of 4.1 K was observed when the liquid helium reservoir was evacuated. As an electron detector, a micro channel plate (MCP) was set on the bottom of the liquid helium reservoir cooled at ∼10 K. The performance of the MCP at low temperatures was examined by using ultra violet light as an input signal. It was confirmed that the MCP has a sufficient amplification at 11.9 K.
