23A SOLENOID has two (three) real attributes:
24<ul>
25<li>L:
26The length of the solenoid (default: 0 m)
27<li>KS:
28The solenoid strength <i>K<sub>s</sub></i> (default: 0 rad/m).
29For positive KS and positive particle charge,
30the solenoid field points in the direction of increasing <i>s</i>.
31<li>KSI:
32The solenoid integrated strength <i>K<sub>s</sub>*L</i> (default: 0 rad).
33This additional attribute is needed only when using the <emph>thin</emph> solenoid,
34where <i>L=0</i>!   
35<li><font color=ff0000><i> KNL & KSL:
36Take note that one can specify multipole coefficients but they have no
37effect in MAD-X proper but are used for solenoids with multipoles in
38PTC.</i></font>
39</ul>

43Example:
44<pre>
45SOLO: SOLENOID, L=2., KS=0.001;
46THINSOLO: SOLENOID, L=0, KS=0.001, KSI=0.002;

51The <a href="local_system.html#straight">straight reference system</a>
52for a solenoid is a cartesian coordinate system.
