ABSTRACT GEM Amplifier Shaper Tracking ON Events (GASTONE) is a low-noise low-power mixed analog-digital ASIC designed to host 64 channels to readout the GEM inner tracker (IT) detector foreseen in the upgrade of the KLOE apparatus at the LNF e+e− DAFNE collider. Each channel is made of a charge sensitive preamplifier, a shaper, a discriminator and a monostable. Digital output data are transmitted via serial interface at 100 Mbit/s data rate. The chip has been developed by using the AMS CMOS 0.35 process. A 16 channels prototype has been produced and used to instrument the single layer IT prototype that has been tested with cosmic muons and a proton beam test at CERN.

    ABSTRACT: A general purpose FPGA based DAQ module has been developed. This module has been built around a Virtex-4 FPGA and it is able to acquire up to 1024 different channels distributed over 10 slave cards. The module has an optical interface, a RS-232 port, a USB and a Gigabit Interface. The KLOE-2 experiment is going to use this module to acquire data from the Inner tracker. An embedded processor (Power PC) is present on the FPGA and a telnet server has been developed and installed. A new general purpose data taking system has been based on this new module to acquire the Inner Tracker. The system is presently working at LNF (Laboratori Nazionali di Frascati).
