Scanning probe microscope Liquid helium-free ultra-high vacuum low temperature scanning tunneling microscope system USM1800
Unisoku Co., Ltd.
About This Product
Achieves atomic resolution STM of 6K or less using a mechanical refrigerator, allowing continuous cooling for long periods of time without using rare liquid helium. An ultra-high vacuum scanning probe microscope that achieves 6K without the use of liquid helium will be released.
Not only is it free from the use of cumbersome and expensive liquid helium, but it also provides a temperature environment and energy resolution comparable to conventional helium-based devices, allowing for long-term STM that was previously not possible due to the addition of refrigerant. enable measurement.
■Features
・Minimum temperature 6K or less: When optical access shutter is closed
・Continuous cooling, rapid cooling: In principle, cooling can be maintained for over 1 year
・Atomic resolution guaranteed: 2pm/√Hz or less
・Optical access, in-situ deposition: internally movable lens
■Applications
・Updating low-temperature STM equipment that uses liquid helium
・Observation of quasiparticle interference patterns using tunnel spectral mapping (STS) measurements
・Observation of low-temperature adsorption structure by in-situ deposition
・Photoexcitation SPM using internal optical lens
■Installation requirements
・Recommended installation area Floor area: 4m x 4m, Ceiling height: ø2.8m
- Floor vibration level <1μm/s (rms) below 5Hz, <3μm/s within 5-10Hz, <5μm/s above 10Hz
・Preparation Equipment: Cooling water, three-phase power
