Gate-Users,<BR><BR>I want to use an analytical source with a shape of a
cylinder.<BR>So I use<BR>/gate/source/addSource

Cylinder<BR>/gate/source/cylinder/gps/radius 90
mm<BR>/gate/source/cylinder/gps/radius0 25
mm<BR>/gate/source/cylinder/gps/halfz 45 mm<BR><BR>But I don't want the axis
of the cylinder to be parallel to z-axis, but <BR>to be parallel to
y-axis.<BR>I tried to write<BR>/gate/source/cylinder/gps/halfy 45
mm<BR>instead of halfz, but this command is just ignored.<BR>Is there any
possibility to turn the source, so that the axis is <BR>parallel to y?<BR>I
could not find anything in the UsersGuide or in the Gate-Users Archives.<BR>I
would be very glad about every help.<BR>Thanks.<BR><BR>Kind
