Explore sub-Kelvin physics with HelioxVT, a compact helium-3 sample-in-vacuum insert designed for integration with helium-4 variable temperature inserts (VTIs). Compatible with new or existing TeslatronPT and TeslatronPT Plus, HelioxVT extends their temperature capabilities down to 300 mK.
With a sample temperature range of 300 mK to 300 K, HelioxVT supports research in quantum materials, superconductivity and low-dimensional physics.
Its self-contained design requires no external gas handling system, helping to simplify experimental setup and operation.
High magnetic fields and low temperatures for hall effect and quantum hall effect measurements.
IInvestigate the effect of low temperature and high field on low dimensional materials; nanowires, nanotubes, quantum dots and 2d electron gases.
Spin processing and data storage studies using high magnetic fields and low temperatures.
Lake Shore Model 346 Cryogenic Temperature Controller
HelioxVT now benefits from upgraded control electronics and software, combining the Lake Shore Model 346 cryogenic temperature controller with Quantum Design Oxford's cryostat control software, DECS, to deliver a streamlined user experience.
The Lake Shore Model 346 provides precise, stable temperature control, while DECS offers a browser-based interface for convenient system operation, with remote access, continuous data logging, and automated control capabilities.
Together, these provide a modern control platform for HelioxVT, allowing researchers to spend less time on setup and operation, and more time focusing on their research.
HelioxVT includes 24 constantan DC lines arranged as 12 twisted pairs as standard. An additional line-of-sight (LOS) port provides space for custom wiring or can be supplied pre-wired with one of the options below.
| Wiring Option | Description | Best For |
|---|---|---|
