Description
The ALPACA experiment is a new air-shower array experiment in Bolivia, with high sensitivity for gamma rays above 100 TeV. The prototype of the array, ALPAQUITA, is currently fully operational, with one about 1/4 of the total area of the full array.
With the goal of enabling long-term operation and future extensions, we have started developing new trigger electronics using modern programable logic devices (FPGA+CPU). Using this novel architecture, we are also developing a novel trigger aiming at improving the sensitivity of the experiment at lower energies. Furthermore, to evaluate the performance of the system, we developed a custom-made pulse generator capable of reproducing the timing characteristics of the air-shower experiment. In this paper, we will present the details of the design of the new trigger system, as the performance evaluation using the pulse generator.
