17. reduce to the current to give the desired field setting Approaching the desired field from a higher setting will typically produce better field uniformity This 1s because the field changes at the pole edges will normally lag the field change at the center thereby helping to compensate the radial decrease in field Greater precision in setting up the calibration curve will be achieved with the use of a digital teslameter and by making a numerical table This table used with an interpolation routine will eliminate the error associated with reading a graph In any event three points need to be remembered 1 A calibration curve or table is only as good as the precision employed in generating it 2 The field is defined only at the point it is measured It will generally be different at a different point in the air gap For example the induction curves refer to the field on the pole axis and at the center of the air eap median plane 3 The field is most directly a function of the current in the magnet coils Voltage across the coils is not a good measure of field since the electrical resistance of the coils depends on the temperature about 0 4 per degree celsius 4 1 Section 4 OPERATION Field Control Operation The necessity to use calibration curves can be avoided by using a field controller to sense the magnetic field and provide a corresponding power supply control signal through the power supply programming inputs Contact GMW for

41. ulating cooling systems use distilled or deionized water with a biocide to prevent bacterial growth and corrosion Do not use corrosion inhibitors in high quality electrical systems since the water conductivity 1s increased which can result in increased leakage currents and electrochemical corrosion Cooling continued At currents of approximately 20A and below the Model 5403 can be operated safely without water cooling However the coil temperature will vary with the power dissipation This results in dimensional changes of the magnet yoke and air cooling is not suitable when high field stability 1s required Freon oil ethylene glycol or other cooling mediums can be used The flow required will be approximately inversely proportional to their specific heats An experimental determination of the flow and pressure required will be necessary Avoid cooling the magnet below the dew point of the ambient air Condensation may cause electrical shorts and corrosion During operation the resistance can be checked using a voltmeter across each coil The voltage will rise to a constant value once thermal equilibrium has been reached If it is desired to save water the flow can be reduced until the hot resistance 1s approached NOTE This adjustment must be made slowly enough to allow for the thermal inertia of the coils 3 3 Section 4 OPERATION General The magnet operates as a conventional electromagnet 1 Adjust the poles to the desired gap w
