Abstract
The results of the in-beam tests of the final version of the DSSD modules for the Silicon Tracking System of BM@N experiment at JINR NICA facility are presented. Each module consists of a double-sided microstrip silicon sensor and front-end electronics connected to each other via low-mass aluminum microcables. Investigations of the module characteristics and tests of the readout electronics were done at proton synchrocyclotron SC-1000 in Petersburg Nuclear Physics Institute. Signal-to-noise ratio, spatial resolution and detection efficiency were measured. Performance of the areas with strips with a second metallization layer and strips with bonding failures was studied. Dependencies of the main operation parameters of the modules on the bias voltage and ADC threshold were also obtained. The average registration efficiency of the modules resulted in values higher than 99% with signal-to-noise ratio typical values for both sides of the sensor not less than 21 and a spatial resolution of .
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
