New instrument capabilities

CTAX/CG-4C: 11-T vertical-field magnet (base temperature is 1.5K)

HIDRA/HB-2B: Recently HIDRA demonstrated the ability to map samples under high temperatures (up to 1200C), in atmosphere or in an inert gas using the Sample environment Controlled Atmosphere Furnace (CAF). If your work would benefit from this capability, now is a great time to utilize this new sample environment.

Also for HIDRA, a new 20kN capacity uniaxial load frame is slated to be delivered by the end of CY 2024. This frame can rotate about the loading axis for use on MARS, GPSANS, HIDRA and WAND². The plan is this load frame will be available as a possibility for friendly users in 2025. Please contact the instrument team for more information.

WAND²/HB-2C: In addition to existing sample environments (temperature control from 50mK to 1800K, pressure up to 20 GPa, cryomagnets up to 6T, humidity chamber, etc.), WAND² is commissioning an in operando battery cell and Z-stage by the end of 2024.

VERITAS/HB-1A, PTAX/HB-1, TAX/HB-3, CTAX/CG-4C, and WAND²/HB-2C – A uniaxial pressure stick capability is now available that can apply a compressive force up to 300 lbs on a single crystal sample. This stick can operate with temperatures between 1.5 and 300 K and magnetic fields between 0 and 6 T.
