Description

The TA-EUSO project aims to install a prototype of the JEM-EUSO telescope on the Telescope Array site in Black Rock Mesa, Utah. The detector consists of one Photo Detector Module (PDM), identical to the 137 present on the JEM-EUSO focal surface. Each PDM is composed by 36 Hamamatsu multi-anode photomultipliers (64 channels per tube), for a total of 2304 channels. Front-End readout is performed by 36 ASICS, with trigger and readout tasks performed by two FPGA boards that send the data to a CPU and storage system. Two 1.5m diameter Fresnel lenses provide an 8 degrees field-of-view of the telescope. TA-EUSO will be housed in a container located in front of the fluorescence detector of the Telescope Array collaboration, looking in the direction of the ELF (Electron Light Source) and CLF (Central Laser Facility). Aim of the project is to cross-calibrate the response function of the EUSO telescope with the TA fluorescence detector in presence of a shower of known intensity and distribution. An initial run of about six months starting from fall 2012 is foreseen, during which we expect to observe – triggered by TA electronics – a few cosmic ray events which will be used to further refine the cross-calibration between the two instruments. In case of continuation in the context of a longer term program, we are considering to increase the number of PDM and the field of view.
