Summary talk on fiber tower calorimeter for the scintillation calorimeter subgroups
We present here a new calorimeter design based on small scintillator tiles, lead absorber and wavelength shifting fiber readout. We have addressed all the major issues in SSC calorimetry and have developed a design with many advantageous features. It has been well demonstrated that the best resolution is obtained for a 'compensated' calorimeter. It is also well known how such compensation may be achieved by a suitable choice of active and passive materials and their relative thickness. One such choice is that of lead and scintillator for which the best thickness ratio is 4:1. This selection has been used in the development of the so-called spaghetti calorimeter (SPACAL) discussed at this workshop. The relative merits of this and many other designs have been the subject of much discussion at SSC workshops from which a number of critical issues have emerged for each design. In the present paper, we have addressed the issues raised in the SPACAL design and proposed an alternative, improved design. The SPACAL represents a significant step forward in calorimeter design, but there are always areas which can be improved in any design when it is subjected to detailed study. Specifically we have considered the areas of energy resolution, channeling, projective towers/calibration, longitudinal segmentation, and radiation sensitivity. We will now discuss each of these areas in turn. 5 refs., 9 figs.
