T/RHH060/19 - Supply of a Physical Properties Measurement System (PPMS)

UKAEA wishes to procure a Physical Property Measurement System (PPMS) offering a wide range of magnetic, thermal and electrical measurements. It has the following minimum requirements: - “cryogen free”, i.e. operated with a cryocooler; - Sample environment controls including fields up to ±14 tesla; - variable temperature insert (VTI) with a calibrated Cernox resistive temperature sensor or direct equivalent, provided with a calibration from 1.4 K to room temperature - Measurement temperature range at least between 2 and 300 K - Time to sweep to 90% of full field less than 10 min, with a thermal load on the insert - Field homogeneity ±0.01% over 3 cm on axis - Capable of performing the following measurements: o Heat capacity o DC magnetic moment (magnetometry) o AC susceptibility o DC and AC electrical properties - A sample rotator to perform a measurement with the field at different angles
