Abstract
Two prototype lead glass calorimeters have been constructed and tested at the AGS at Brookhaven National Lab. The first is a 25-element prot otype (P1) which was tested in the A2 beam line using electrons and pi ons ranging in energy from 0.5 to 5.0 GeV. Results were obtained on en ergy resolution, the effect on energy resolution of pre-radiators and non-normal incidence, and on e/pi separation. The second prototype (P2 ) has 319 elements and was tested in the A3 beam line using 3.0 and 5. 0 GeV electrons and 15.0 GeV negative pions. Results were obtained on position resolution and effective mass resolution. Data were collected requiring multi-photon signatures in the calorimeter. The design, con struction, monitoring, readout electronics (including a custom-built f ast-encoding ADC system) and testing of the prototypes are described. These calorimeters are prototypes for a 3053-element lead glass calori meter being built for Brookhaven Experiment 852: a search for mesons w ith unusual quantum numbers. Quality control procedures are also discu ssed.
