Source calibrations and SDC calorimeter requirements

Description: Several studies of the problem of calibration of the SDC calorimeter exist. In this note the attempt is made to give a connected account of the requirements on the source calibration from the point of view of the desired, and acceptable, constant term induced in the EM resolution. It is assumed that a local'' calibration resulting from exposing each tower to a beam of electrons is not feasible. It is further assumed that an in situ'' calibration is either not yet performed, or is unavailable du… more

The effects of cracks on calorimeter response in the SDC dogleg'' design

Description: In an initial attempt to set the scale for cracks, the reaction H(800) [yields] ZZ [yields] (q + q) [yields] ([tau]l +[tau]2) [yields] ([rho]l + [nu]i) + ([rho]2 + [nu]2) was studied. The figure of merit was taken to be the Z transverse mass, i.e. the mass of ([rho]1 + 2 + E[sub T]). With no cracks in the coverage save the beam holes at [eta] = 5, this quantity has a fractional spread of [approximately] 12%. The additional contribution of cracks was unfolded in quadrature. Clearly, the scale wh… more

Description: Several studies of the problem of calibration of the SDC calorimeter exist. In this note the attempt is made to give a connected account of the requirements on the source calibration from the point of view of the desired, and acceptable, constant term induced in the EM resolution. It is assumed that a ``local`` calibration resulting from exposing each tower to a beam of electrons is not feasible. It is further assumed that an ``in situ`` calibration is either not yet performed, or is unavailabl… more

Radiation damage in the SDC hadronic endcap calorimeter

Description: Detectors for the SSC face a radiation field which is very dependent on angle. For example, the SDC barrel'' calorimeter can function well for 100 year operation of the SSC running at desip luminosity, while the small angle forward calorimeter'' faces Grad of radiation in the same period. The SDC endcap'' calorimeter is in an intermediate location. One wishes to examine whether it might be possible to use conventional scintillator technology with periodic refurbishment in the endcap- The angula… more

Radiation damage of tile/fiber scintillator modules for the SDC calorimeter

Description: The measurements of radiation damage of tile/fiber scintillator modules to be used for the SDC calorimeter are described. Four tile/fiber scintillator modules were irradiated up to 6 Mrad with the BEPC 1.1 GeV electron beam. We have studied the light output at different depths in the modules and at different integrated doses, the recovery process and the dependence on the ambient atmosphere.
