First attempts to use the last version (IV) of the Domino Ring Sampler (DRS) chip for time profile analysis of PMT signals produced in dual-readout calorimeters are described. Time characteristics of the signals sampled with a simple DAQ system based on evaluation boards with the DRS-IV chip are compared with those of equal signals processed with a high performance digital oscilloscope. Separation...
The feature-extraction algorithm, developed for the digital front-end electronics of the electromagnetic calorimeter of the PANDA detector at the future FAIR facility, is implemented in VHDL for a commercial 16 bit 100 MHz sampling ADC. The use of modified firmware with the running on-line data-processing algorithm will allow to perform realistic performance studies of the calorimeter and test a trigger-less...
For X- and γ-ray astronomy in the coming decades, both ESA and NASA have indicated in their guidelines the importance of developing innovative instrumentation operating in the hard X- and soft γ-ray range where important scientific issues are still open, exploiting high sensitivity (50-100 times better than current instruments) for spectroscopic imaging and polarimetric observations. In this framework,...
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 a USB and a Gigabit Interface. The KLOE-2 experiment is going to use it to take data from the Inner tracker and the QCALT. An embedded processor (power pc 604)...
The Daya Bay RPC readout system is responsible for collecting Muon hit events for the anti-neutrino procedure.The expected readout system should be capable of converting analog hit signals from RPC (Resistance Chamber Plate) detectors into digital signals which will be buffered and then uploaded to online DAQ (Data Acquisition) systems as well as reporting trigger information. The numerous and relatively...
