“…N a previous work [1] we described the results obtained by applying Digital Pulse Shape Acquisition (DPSA) to the CHIMERA [2] 4π-multidetector telescopes. These telescopes are made of thin large area Silicon detectors (300 μm thick, 5x5 cm 2 active area) coupled with thick CsI(Tl) scintillators (up to 12 cm thick).…”

We designed and built a 16-channel NIM module acting as preliminary analog processing of the signals to be converted by sampling ADCs for the CHIMERA 4π multidetector digital pulse shape acquisition system. The main functions of the module are: i) a second order anti-aliasing filter with two programmable cutting frequencies, ii) a programmablegain amplifier to cope with the full dynamic range of the ADC, iii) a programmable output offset voltage with AC or DC input coupling selection. In addition, a buffered replica of input signals is present on the front panel to serve the conventional analog acquisition chain. All the module parameters are programmable through an RS485 serial interface.

“…I N view of new -detector projects for heavy ion nuclear physics experiments at intermediate energies, we have investigated the applicability of digital signal processing methods to a typical CHIMERA [1] detection cell (large area cm -Si-CsI(Tl) telescope). In our previous work [2]- [4] we have shown the high precision results obtained by collecting pulse-forms directly from the CHIMERA telescope preamplifiers.…”

The digital pulse shape data acquisition (DAQ) system used by the large area telescopes of the 4 -multidetector CHIMERA requires transferring large amount of data to the computer. This is necessary so that the same information can be extracted from the detector pulses as in previous analog based systems. To overcome this problem, we have used a sampling ADC-board equipped with two TigerSHARC digital signal processors. The board receives the data and reconstructs the event parameters online. The data volume is significantly reduced by transmitting to the DAQ only the reconstructed event parameters.Index Terms-Digital signal processors, mass and charge identification, nuclear measurements, nuclear physics, online and on-board digital signal processing.

“…CsI(Tl) scintillators, on the contrary, emit light pulses whose shape varies with the type of incident radiation. As is well known, the decay of the light emitted by the CsI(Tl) is given by the sum of two exponential functions, called fast and slow components (1) Manuscript received November 12, 2003 where is the light pulse amplitude at time and and denote, respectively, the decay constant of the fast and slow components of the light pulse. Typical values are s, s. Discrimination among LCP is possible essentially because the ratio between the amplitudes of fast and slow components is a function of mass, charge, and energy of the detected product.…”

“…In order both to improve the LCP-Id and to simplify the electronic chain of multidetector telescopes, we have carried out some tests using commercial sampling analog-to-digital converter modules to perform real-time digital pulse-shape analysis of the signals coming from a standard detection cell of a CHIMERA (Charged Heavy Ion Mass and Energy Resolving Array) multidetector [1], [2], (i.e., a telescope of a 300 m silicon detector and a cm CsI(Tl) scintillator coupled to a photodiode). First, we have performed the on-beam and on-line LCP-Id for the CsI(Tl), by using only the standard electronic chain for measuring slow components with CHIMERA, with the charge-todigital converter (QDC) replaced by the sampling analog-todigital converter.…”

A 100 Msamples/s 14-bit sampling analog-to-digital converter has been used to perform digital pulse-shape acquisition of signals collected from CHIMERA telescopes. Two different kinds of tests have been carried out to check the performances. The signals from a typical CHIMERA detection cell have been collected using both a standard CHIMERA electronic chain up to the amplifier, and a very simple analog front end, basically reduced to the preamplifier. The obtained on-beam and on-line results are presented.Index Terms-Digital pulse shape acquisition, digital signal processing, multidetector arrays, particle identification, simple analog front end.
