Abstract
A method for the removal of debris (75) from an aperture (60), the aperture comprising a first aperture diameter (64) and extending along a first axis (62) over a first distance (63), the method comprising the steps of aligning a beam of energy (80) with the first axis such that the beam of energy is coaxially aligned with the aperture, the beam of energy comprising both an energy sufficient to remove the debris, and a first beam diameter (82) which is less than the first aperture diameter; and, exposing the debris to the beam of energy in order to remove the debris from the aperture.
Claims15
A method for removal of debris from an existing aperture, the aperture comprising a first aperture diameter and extending along a first axis, defined by the existing aperture, over a first distance, the method comprising the steps of:
- aligning a beam of energy with the first axis such that the beam of energy is coaxially aligned with the existing aperture, the beam of energy comprising both an energy sufficient to remove the debris, and a first beam diameter which is less than the first aperture diameter;
- and
- exposing the debris to the beam of energy in order to remove the debris from the existing aperture and wherein at least a portion of the debris at least partially covers an entrance of the existing aperture, the step of exposing the debris to the beam of energy including the step of removing the debris from an entrance into the existing aperture.
