5 OPERATING THE MAGNET
Standard
Mercury
iPS’s home screen in single axis solenoid (or split-pair) mode is shown below
(Figure 13). This screen has the principle controls required to energise the superconducting
magnet attached to the output terminals of the power supply group. These controls are
described in section 3.5.1.
Figure 13. Magnet Home screen in “Solenoid (or Split Pair) mode”
To energise the magnet it is necessary to enter a set point (target current or target field) and a
set ramp rate at which to ramp the magnet current. To do this, tap on the “Current (A)” display
of the Home page (Note: if the Home page is in “Tesla” mode, tap on the “Field (T)” display).
This will bring up the “Set Point / Set Rate” page show below (Figure 14).
To enter a set point tap on the “Set Point” box to open the numeric keypad. Enter the value of
the current (or field) you want to ramp to and tap OK. The value will appear in the box. Take
care to note which mode the iPS is in which is defined by the Amp/Tesla button on the Home
screen. If you enter the “Set Point / Set Rate” page in Amp mode the settings will be in Amps
and Amps/minute. If you enter the “Set Point / Set Rate” page in Tesla mode the settings will
be in Tesla and Tesla/minute.
Similarly, to enter a set rate tap on the “Set Rate” box to open the numeric keypad. Enter the
value of the current rate (or field rate) you want to ramp at and tap OK. The value will appear in
the box. Tap Home to return to the Home screen.
