14           This will describe how to set the SOS magnets by momentum.

17           \section{Getting Started}
18           First, you will need the SOS magnet controls.  From a terminal, type
19           "telnet vmec19" and use "cvxwrks" as the login and the password can be
20           found written somewhere around the slow controls computer.  Once you
21           log in, type "SOS" and press "ENTER".  A menu should appear. Now,
22 saw   1.1 you're ready to set the magnets
23           
24           \section{Degaussing}
25           You should degauss the magnets if you're changing the polarity or if
26           the "degauss needed" fields say "yes."  To degauss the magnets, select
27           either "degauss(electrons)", item 13 on the menu, if you want negative
28           polarity or "degauss(protons)", item 12 on the menu, if you want
29           positive polarity.  The magnet status field will indicate when the
30           degaussing process is complete.
31           
32           \section{Setting the Magnets}
33           Magnets will be turned on one at a time, but the order is not
34           important.  First, choose "select power supply", item 1 on the menu.
35           Choose 1, 2 or 3 and press enter.  Next, select "turn power supply
36           on", item 2 on the menu, This will turn on the magnet you just
37           selected.  Repeat for the other magnets.  To select positive polarity,
38           select option 5 from the menu, or option 6 for negative polarity.  If
39           this happens too soon after the power supplies are turned on, you will
40           receive a message instructing you to wait some number of seconds.
41           Once they're all on, select "set by momentum", item 9 on the menu, and
42           enter the appropriate momentum.  Make sure to include the minus sign
43 saw   1.1 if you're setting the magnets to negative polarity. You will see the
44           magnets ramping in the status field.
