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
