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.

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.
