The SpecMAT active target

The GET electronics for scintillation detectors readout

“…The output energy signal has exponential shape with the rise time of 250 ns from 0 to 100 % and the decay time of 0.55 µs from 100 to 63 %. A detailed description of the detector is given in [9] and [10]. The GET hardware configuration included one ASIC 3 and ADC 4 (AsAd) board, one Concentration Board (CoBo) and one Multiplicity, Trigger and Time (MuTanT) module.…”

“…The GET electronics was configured to acquire signals with an external this electronics line was used to reduce the rate of the trigger signal similarly as described in [9], [10] and [13]. The measurements described below do not aim at an accurate identification of the detector efficiency but rather at optimisation of the energy resolution of the acquired γ-ray spectra.…”

“…Auxiliary detectors are usually coupled to ATs to detect and identify these particles that escape the gas-filled volume of the detector. For example, ACTAR [6,7] has arrays of double-sided silicon strip detectors (DSSSD), and TexAT [8] uses large CsI/Si telescopes for stopping charged particles; the SpecMAT active target [9,10] is surrounded by an array of CeBr 3 scintillation detectors for γ-ray spectroscopy. Because the electronics was primarily designed for MPGDs used in TPCs and ATs, its performance is subject to tests for other detector types that are usually coupled to ATs.…”

Enhancing the performance of solenoidal spectrometers for inverse reactions

“…This combines the HELIOS concept with that of the time-charge projection chamber (TPC), the latter employed successfully in low-energy nuclear physics applications for two decades (see, e.g. [16,17]) and more recently operating inside a solenoidal magnetic field [18,19]. For recent reviews of active targets, see [20,21].…”
