magnet power supply. The linear regulated power supplies normally used in laboratories for this purpose have a peak power dissipation of 100-500 W. Fortunately, this power consumption could be dramatically reduced by redesigning the magnet and power supply. By using more turns of thinner wire, the c
A centrifugal pump used for c~rculatmg hqutd hehum through a large superconducting magnet was tested The performance of the pump was measured during a magnet coohng test The pump operated well wtth atyptcal capacity of 400 dm 3 h -~ (Ap = 0 3 kg cm-2) at 20000 rpm An analys~s of the test results ~s
This Paper summarizes and correlates the liquid helium pump data obtained previously in two separate test programs, In normal helium the second set of data shows a large performance improvement over the first set as a result of changes in measurement methods and in the pump itself. Peak pump efficie
