B.41 Oxford Instruments Magnet Sweep Power Supply IPS120-10 with DAC modulation input
Description: Power supply for the Oxford Instruments superconducting magnet previously used for the Leiden W-band spektrometer. This is an older version of the IPS120-10 with a current resolution of 10 mA. Therefore it has been fitted with an external voltage input that allows to modulate the output current by about +/- 5% of the maximum rated current of 120 A by a voltage in the +/- 10 V range. The external voltage is supplied by a RULBUS RB8510 DAC card, which has a voltage resolution of 5 mV, resulting in a current resolution of 0.3 mA and a field resolution of ca. 0.125 G. Please note that this improved resolution applies only when a field is set, the sweep step resolution remains unchanged (and sweeps thus should probably be avoided when using this device).
Controlled via: GPIB bus (the device has a (non-standard)
serial port, a
GPV24 interface for conversion between
IEEE488 is employed).
