AbstractAbstract
[en] The response of the TAMU Forward Hadron Calorimeter Chambers to neutrons from a 239Pu-Be source was investigated in hope of developing a strategy to reduce the effects of the background events called /open quotes/Texas towers/close quotes/ in the CDF trigger for the next run. The response to a standard (55Fe γ-ray) energy source was also studied and found to be similar to that of the chambers installed at CDF. In addition, the effects of different sampling gases and intermediate absorbers on the rate of large energy pulses were investigated. The neutron data were compared with the energy spectrum measured in CDF and that simulated using Monte Carlo techniques. It was found that the large energy pulse frequency can be reduced by as much as 50% if a non-hydrogenous sampling gas is used in conjunction with a neutron moderator
