1. Report’s topic: “Prospects for the development of experimental facilities for space radiobiology at the NICA complex”

   Speakers: G. N. Timoshenko, I. S. Gordeev (LRB JINR)

   Аннотация:
   
   – The structure of the radiobiological channel at the Nuclotron, the Laboratory of High Energy Physics (the SODIB Biological Station for Long-Range Ion Irradiation), and possibilities of carrying out radiobiological experiments with relativistic heavy ions there.
   – A simulator of the GCR-induced radiation field inside a spacecraft and prospects for its creation at the SODIB.
   – A proposal of providing a field of chronic irradiation of laboratory animals similar in composition to GCR based on a non-target gold ion beam from the NICA booster.




2. Report’s topic: “A single-photon emission computed tomography system with submillimeter resolution based on a timepix detector with an encoding collimator”

   Speaker: Vladislav Rozhkov (DLNP JINR)

   Abstract:
   
   A single-photon emission computed tomography (SPECT) system based on a Timepix detector with an encoding collimator is presented, developed at the Laboratory of Nuclear Problems. The use of a CdTe-based semiconductor matrix detector and a Timepix readout microcircuit as a recording device makes it possible to carry out research on laboratory animals using multinuclide radiopharmaceuticals with high energy and submillimeter spatial resolution. The system’s main performances are presented; examples of 2D and 3D images obtained with calibration phantoms are shown. Possible development of the system is discussed, including changing the field of view and spatial resolution, as well as the possibility of creating a scanner based on the SPECT facility. The facility’s performances are compared with those of commercial analogs.
