Disclosed herein are systems and methods for advancing tape/ribbon through
a targeting area where laser ablation of the tape occurs in laser
produced plasma equipment. Disclosed systems include a first positioning
surface perpendicular to further positioning devices, where all of the
positioning components work to precisely position the advancing tape in
the point source area. After the first positioning device, the remaining
positioning surfaces are parallel and provide positioning forces on the
tape along a single horizontal axis, but in alternately opposing
directions. Such forces assist to precisely position the tape in the
desired target location, and to control the rate of advancement of the
tape by imparting friction on the tape in alternating, opposing
directions. A steady drive roller serves to pull the tape through the
system, and works in conjunction with the friction imparted by the
positioning surfaces to advance the tape at a substantially constant
velocity.
