“…The differential signal from the charge preamplifiers is fed to custom anti-aliasing amplifiers [18] featuring adjustable bandwidth to fulfill the Nyquist requirement and adjustable gain. For every strip, the amplified waveform is digitized by eight SIS3301 SADC boards [19] at a sampling frequency of 100 MS/s.…”

Abstract-Silicon microstrips are widely used in nuclear physics experiments when high granularity and high resolution of the detection system is required, as, for example in particleparticle correlation measurements. In addition microstrip detectors are used in the field of X-ray detection for position resolved X-ray spectroscopy.In order to surgically probe the response of the interstrip region we tested the detector response matrix both in back and in front injection with an infrared pulsed laser at two different wavelengths (705 nm and 904 nm) in order to probe different ionization profiles. Depending on the side of interaction, on the position of incidence and on the absorption length, the shapes of the induced signals are significantly altered and signals of opposite polarity or bipolar signals arise. This phenomenon was already observed in the literature for other microstrip detectors but not analyzed in detail and no detailed laser mapping has been performed yet. In order to get a complete picture of the physical phenomena at the basis of the aforementioned behavior we performed detailed device simulations with a custom semianalytical code and compared the experimental results with 3D simulations. The paper focuses on the description of the experimental measurements and their exhaustive interpretation.

“…The signal coming from the preamplifiers are fed to a custom anti-aliasing filter and amplifier [13], modified with a differential input receiver, providing the required antialiasing filter (second order) with two programmable cutting frequencies (8 MHz and 40 MHz); a user-selectable gain (1×, 2×, 4×, 8×) to cope with the full dynamic range of the ADC; the selection of the polarity of the output signal and a programmable output offset voltage with AC or DC input coupling selection. The signals from the AAAs are digitized with a set of sampling ADC boards, hosted in a VME crate located in the controlled area.…”

We are currently developing a novel detection system, named FARCOS (Femtoscope Array for Correlation and Spectroscopy) and featuring high angular and energy resolution and able to reconstruct particle's momentum at high precision for different physical cases in multi-fragmentation nuclear physics experiments. Performing a Pulse Shape Analysis on signals coming from the ΔE stages -Double Sided Silicon Strip Detectors (DSSSDs) -we aim at identifying in charge and mass even particles stopping in the first detection layer. In the framework of the full characterization of the DSSSD response in terms of both the linearity of the amplitude response and of the efficiency and collection properties as a function of the point of incidence, we got evidences of significant alterations of the signals shape in case of particle injection in the inter-strip region. Such an effect, which depends also on the type and energy of the impinging particle, cannot be ascribed only to a mere charge division, especially in case of signals with "wrong" polarity, but to more complex phenomena -for instance charge induction on neighbor strips.In this work we present the results of the qualification campaign carried out exploiting the monochromatic pulsed proton beam facility available at LaBeC of INFN -Sezione di Firenze, focusing the attention on the aforementioned "inter-strip effect". We interpreted the measurements also with the aid of dedicated 3D simulations performed with a custom semianalytical code, which gives a better insight on the physics Manuscript occurring in the device. The impact of the "inter-strip effect" on particle identification scatter plots is also discussed.

“…However, with severe restrictions on energy consumption [1], many tasks of construction of sensor interfaces based only on DSP have not been solved [2,3]. In addition, input analog anti-aliasing filters (spectrum limiters), as a rule, are an integral part of various ADCs [4,5] and affect their errors.…”

A new structure of the second-order lowsensitivity active RC filter (ARCF) with an extended frequency range is proposed. The ARCF circuit is implemented on three operational amplifiers (OA) and is recommended as a universal link in the construction of bandpass filters, as well as anti-aliasing low and high pass filters for operation in structures with analog-to-digital converters (ADC). It is shown that, due to the introduction of a new connection, additional difference coefficients appear in the transfer function of the ARCF under consideration, depending on the gain areas (GA) of the OA, which enables to reduce the effect of the frequency properties of the OA on the realizable characteristics at low power consumption. The circuit design of a low-temperature radiation-hardened OA on complementary junction field-effect transistors, designed for operation in severe conditions, is considered.
