          Appeal No. 97-0128                                                          
          Application No. 08/098,989                                                  


          result of this amendment, the Examiner allowed claims 2-5 and               
          9 as indicated in the advisory action mailed March 23, 1995.                
               The claimed invention relates to a system for the                      
          development of a conditioned electron beam for application to               
          a free-electron source of coherent radiation.  More                         
          particularly, Appellants indicate at page 3 of the                          
          specification that the system includes sources for generating               
          an electron beam and microwaves and a magnetic wiggler                      
          responsive to the generated electron beam and microwaves to                 
          develop the conditioned electron beam.                                      
               Claim 1 is illustrative of the invention and reads as                  
          follows:                                                                    
          1.   A system for developing a conditioned electron beam of a               
          final quality for application to a free-electron source of                  
          coherent radiation, said system comprising:                                 
               means for producing an electron beam having a                          
          predetermined energy and initial quality;                                   
               means for generating microwaves; and                                   
               a magnetic wiggler responsive to the electron beam from                
          said producing means and to the microwaves from said                        
          generating means for developing the conditioned electron beam               
          of final quality, higher than the initial quality, to enhance               
          the operation of the free-electron source of coherent                       
          radiation.                                                                  
               The Examiner relies on the following references:
