Abstract

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.
