Multi-User Equipment approved in grant 14/19142-2: ultra-low vibration cryostat with magnetic field and confocal microscope

Abstract

This multiuser equipment comprises an ultra-low vibration helium closed cryostat operating between 4.5 and 300 K with applying magnetic fields up to 9 T, and the confocal microscopy technique associated. The sample is placed in the uniform magnetic field region at the top of piezoelectric x-y-z-stages, and an objective lens compatible with cryogenic temperatures is used for focusing light. In the outer region, all necessary optical and electrical connectors are packaged in a module known as head of the microscope. The combination of thermal stability and low vibration levels, with the versatility of the confocal microscope, added to the absence of costs with cryogenic liquids, makes this system comprehensive enough to the research groups working on optical and electrical properties of different materials.
