          Appeal No. 95-4799                                                           
          Application 07/996,516                                                       

                    This is a decision on appeal from the final rejection              
          of claims 11, 12, 16 and 17.  Claims 1 through 10 have been                  
          cancelled.  The examiner has withdrawn the final rejection of                
          claims 13 through 15 and 18 through 20, indicating them to be                
                    The invention is directed to a radiation detector                  
          employing superconductors rather than the semiconductors employed            
          in prior art detection devices.  The problem with                            
          superconductors, i.e., that increasing surface area for more                 
          efficient detection operation causes a decrease in detection                 
          signal quality due to an increase in capacitance of the tunnel               
          junction, is said to be solved by the invention by providing an              
          optimal number of series-connected superconducting tunnel                    
          junctions for a particular detector.  The number of these tunnel             
          junctions is said to be optimal for a fixed area of the detector             
          when certain relationships between the total area of the                     
          superconducting tunnel junctions and the capacitance per unit                
          area of the superconducting tunnel junctions are established.                
                    Representative independent claim 11 is reproduced as               

                    11. A radiation detection device comprising:
