BACKGROUND

The Functional Nanostructured Materials Group is working to advance measurement science and standards in magnetic thin films and magnetoresistive random access memory technologies. A commercial H-frame electromagnet is used to generate applied fields driven by a commercial ER 083 power supply unit. This power supply unit is a 200 V, 60 A (12 kW) power supply and has reached the end of life. In order to continue using the electromagnet, a compatible power supply is required to deliver current-regulated power to the electromagnet with high stability for precision measurements of magnetic thin films and Magnetoresistive random access memory technologies under well-controlled fields. Such an electromagnet requires an electromagnet power supply system, including a current-regulated power supply, an embedded Hall-effect based Gaussmeter, and feedback-regulated control of the current delivered to the electromagnet to achieve stable field control.

DESCRIPTION OF REQUIREMENT

The Contractor shall provide one (1) electromagnet power supply system that meets all technical specifications identified below: - One bipolar current-regulated power supply unit (unit) with zero-crossing continuity (no use of current reversal switches), with at least 12 kW output power, at least 200 V output voltage and at least 60 A output current. Longterm drift of the current shall be less than 50 parts per million (ppm) over 8 hrs assuming constant temperature, and less than 5 ppm per degree Celsius.Serial or ethernet control of the power supply unit, with integral conversion of the desired set field to better than 18 bits and digitization of analog signals to better than 24 bits - Water cooling of the unit; three-phase, 208 V power input - A digital Teslameter/Gaussmeter with accuracy at +/-0.01 % of reading and +/- 0.006% of the full scale maximum at 25 degrees Celsius. At least three different measurement ranges, with the highest range of at least 3.0 Tesla. - A Hall Effect probe with a 4 m long cable, compatible with the digital Teslameter/Gaussmeter and associated accuracy described in section (6). Temperature compensated over a range that includes at least 10 degrees Celsius to 30 degrees Celsius. - Proportional-Integral-Derivative-based regulation of the power supply current output using the measured field from the Hall effect probe. - A mounting bracket to mount the Hall effect probe to the flat pole face of a commercial Bruker ER 074 electromagnet. - An instructions manual for mounting the Hall Probe and operating the Power Supply using Ethernet signals from a control PC, including commands to set the PID parameters, monitor the magnetic field and the output current and to set the magnetic field and the output current using commands in the Python programming language and provision of the library or module containing those programming commands
