“…Also, the mechanical integration with the support is being actively explored as well as the integration with other MPD subsystems. Moreover, some of the capabilities of the miniBeBe could be enhanced if used together with the BeBe detector that we have also proposed to be considered as a forward beambeam counter [36]. The technical design for the detector will be reported in a more detailed document elsewhere.…”

We present the conceptual design for the miniBeBe detector proposed to be installed as a level-0 trigger for the TOF of the NICA-MPD. We discuss the design and the geometrical array of its sensitive parts, the read-out electronics as well as the mechanical support that is envisioned. We also present simulation results for a wide range of multiplicities obtained in p + p and A + A collisions to study its capabilities, both as a level-0 trigger for the TOF as well as to serve as a beam-gas interaction veto and to locate the beam-beam interaction vertex.

“…Finally, we obtained the fit Gaussian distribution from the set of all mean values to obtain the σ parameter, which it represents the ITR. This technique has been compared with the experiment [1] and also is used to calculate the ITR for the MiniBeBe detector (described in the Section 6 in [2]).…”

“…One of the most important characteristic for a detector is the time resolution (TR), many works have been done to improve it [1]. For the case of the scintillator materials, the detection of optical photons is very important to give the signal, of which, photo-sensors are used, then, the detection area (Scorer ) of them is important, if it is bigger, it has better light collection.…”

The time resolution (TR) is one of the most important characteristic of a detector. For the case of a scintillator, the collection of light also is important, it depends of the effective area of the photo-sensor (Scorer ). The Photomultipliers Tubes (PMTs), normally, have an effective area greater than the Silicon Photomultipliers (SiPMs), however, due to its voltage of operation, their size and cost, in some cases it can be difficult to work with them. In which case, it is preferable to use SiPMs. The value of TR also depends of the size and geometry of the scintillator, number of photo-sensors and the electronic part.In this work, we study the mean optical photon arrival time distribution (AT) to a Scorer from a SiPM of 6×6 mm 2 . We define the variation of AT as the intrinsic time resolution (ITR). In Geant4, we simulated two different geometries: square and hexagonal, for a BC-404 plastic scintillator coupled to one Scorer. The sources simulated were Sr 90 , Co 60 , Cs 137 , Na 22 and µ − of 1 GeV. It is shown that AT and ITR depends of the geometry and size of the plastic scintillator, the location of the Scorer, the incident particle and its energy. Then, the ITR and therefore the TR is not a constant for a detector. Finally, we show the relation between AT and the deposited energy by the particle incident, which are related in the experiment to the response time event of the detector and the deposited charge by the incident particle, respectively.

“…These types of detectors are integrated with other detectors for the optimization in the identification of particles, in particles and ion collider projects such as LHC & JINR ("Large Hadron Collider" and "Joint Institute for Nuclear Research" respectively). The implementation of high resolution detectors not only transcends the field of research in particle physics, and high energies [1,2,17], they also stand out in some industrial security systems (dosimetry, spectrometry, X-rays) [7,15]; these detectors can also be found in hospitals, within some medical imaging equipment, such as X-Rays (XR), Fluoroscopy (RF), Computed Tomography (CT), Positron Emission Tomography (PET) and Scanning Microscopy [5,13,14].…”

The high time resolution detectors are relevant in those experiments or simulations were the particles to detect, have a very short time of flight (TOF), and due this it´s required that the detections times are ranged between ns. & ps.Using Geant4 software, it was made thirty simulations of coupled detectors to plastic scintillators with two silicon photomultipliers (SiPMs) located on the scintillator’s central sides. To characterize the time resolution, it was required to quantify the optical photons that reach the Score in a certain time, which are generated by muons on the surface of the plastic scintillator. Different configurations of muon beams were simulated at energy of 1 GeV, to interact with the configuration of the scintillator material of its corresponding arrangement. The simulations were made varying three parameters: the scintillator material “BC404 & BC422”, its size, and the location of the radiation source. Fifteen simulations correspond to BC404 material & fifteen simulations to BC422 material respectively. The first five simulations consisted in varying the scintillator’s volumetric size and collocate the muons beam guided randomly distributed over it, the next five simulations differentiate from setting up a directly centered beam, and the last five simulations for guide the beam on the left lower corner of each scintillator.The best time resolution achieved was σ= 8.67 +/− 0.26 ps., reported by the detector with BC422 scintillator material which has a volume of 20x20x3 mm3.
