The customized low-temperature 3D probe station of King Abdullah University of Science and Technology in Saudi Arabia has been successfully delivered

Parameter Overview:

High and low temperature tests can be conducted in a vacuum environment (10K~325K). The magnetic field strength is 0.75T on the x-axis, 0.75T on the y-axis, and 0.4T on the z-axis.

Magnetic field uniformity: 1% within a 60mm sphere in the central region.

Three high-precision DC power supplies: stability ± 25ppm

Magnetic field resolution: 0.05 MT

Angle resolution: 0.02 °

Sample fixation method: Low temperature probe

Sample table diameter: 20mm, customizable

Microscope: 10. Y-plane 2 * 2 inches, accuracy 2 μ m, Z-axis stroke ≥ 30.8mm,

Magnification factor: 16~100x/20~4000x

Number of probe arms: 4. optional

Probe arm stroke: 12mm, replaceable

Probe arm movement accuracy: 25 μ M optional

Probe length: 38mm

Probe diameter: 0.51mm

Needle tip diameter: 1 μ m

Probe material: tungsten/beryllium copper/GB

Leakage accuracy: Designed with a 100fa low-temperature radiation proof screen, the sample stage uses high-purity oxygen free copper with good temperature uniformity.

The temperature sensor uses a stable and repeatable silicon diode as the temperature measurement device, supports fiber optic spectral characteristic testing, is compatible with high magnification display mirrors, can be fine tuned and moved, has high frequency characteristics of the device (supporting frequencies up to 40GHz), probe heat sink design, LD/LED/PD light intensity/wavelength testing, automatic flow control, material/device IV/CV characteristic testing, etc.
