Classification of the products to be procured : 2 Nature and quantity of the products to be purchased : Cryogen-Free Physical Property Measurement System Set Type of the procurement : Purchace Basi requirements of the procurement : Temperature Control Performance A The sample chamber must be capable of controlling temperature over a range of 1.8 K to 40 K or wider. B The system must be able to cool the sample from room temperature to K within one hour. C The sample chamber temperature must be stabilized at any setpoint, with a stability of ±0.1% or better below 2 K and ±0.02% or better above 2 K. D Temperature accuracy must be within ±1%. Magneti Field Control Performance A The magneti field must be controllable from zero u to ±1 T or higher. B Magneti field resolution must be 0.2 Oe or better. C Magneti field uniformity must be within ±0.1% over a cylindrical volume of 5 mm height and 1 mm diameter. Sample Chamber Requirements A The sample chamber must provide an internal diameter of 25-3 mm, allowing installation of samples and enabling measurements of various physical properties (e.g., DC electrical resistivity, specifi heat) across a wide range of temperatures and magneti fields. B At least 1 measurement terminals must be available. C The sample chamber must achieve a pressure of 1 Torr within 1 minutes, starting from 1 Torr. Cryocooler Performance A A single cryocooler must be capable of cooling both the sample chamber and the superconducting magnet. B The cryocooler must be a low-vibration pulse tube type. Cryogen Requirement The system must use a very small amount of liquid helium (converted from helium gas by the cryocooler), 20 c or less. Measurement Efficiency The system must allow measurements without requiring a dedicated operator, and must be controllable via a user-friendly interface on a standard personal computer. ⑦ Magneti Shielding Performance The system must be equipped with strong magneti shielding to minimize external stray magneti fields.
