+description=MLZ-Amagnet
+	.
+	Water cooled magnet from ANTARES@MLZ.
+	.
+        Use module to control the magnetic field.
+	Don't forget to select symmetry first (can be moved only at zero field!).
+	.
+	Monitor T1..T4 (Coil temps), if they get to hot, field will ramp down!
+	.
+	In case of Problems, contact the ANTARES people at MLZ.
