Advanced Transport Measurement System (ATMS)
A fully integrated, automated in-situ platform developed to bridge the gap between complex physical phenomena and precision data acquisition. This system unifies custom cryogenic hardware with intelligent software control.
Broad Range Resistivity
Engineered to automate multi-range resistivity measurements spanning 10-8 to 1016 Ω, covering everything from superconductors to high-dielectric insulators.
Fully Automated
Controlled by the in-house PICA software, featuring multithreading for stability and transparent logging to strictly prevent data loss during long-duration experiments.
Multi-Characterization
Seamless switching between I-V characterization, Pyroelectric current measurement, and Magnetodielectric spectroscopy.
Custom Probe Development
Design and fabrication of specialized probes tailored for signal integrity and extreme environmental conditions.
High-Field Environment
Multifunctional PPMS Probe
Designed for the Quantum Design PPMS to investigate materials under high magnetic fields. The architecture prioritizes low-noise signal acquisition and thermal stability.
- Signal Integrity: Utilizes RG178 micro-coaxial cabling to minimize cross-talk and environmental noise.
- Thermal Engineering: Single-crystal Sapphire base for superior electrical insulation and thermal conductivity.
- PCB Design: Custom glass-epoxy PCBs with optimized trace geometry to reduce leakage currents.
- Opto-Electronics: Integrated 650nm laser diode for in-situ photo-induced measurements.
Cryogenic Vacuum System
Liquid Nitrogen Cryogenic Probes
Two specialized probes developed for operations in liquid nitrogen dewars, featuring custom vacuum jacketing and active temperature control.
Probe 1: High-Voltage & Pyroelectric
Optimized for Polarization-Electric Field (P-E) loops and pyroelectric current. Features high-voltage isolation for poling experiments.
Probe 2: Variable Range Transport
Dedicated configuration for precision transport measurements (low to high resistance) with minimal thermal gradients.
