1 Position-sensitive gaseous detectors (PSD) Supervisor:Student: A.V.ChurakovL. Piterka University of West Bohemia Pilsen JINR, DUBNA

2 Fields of neutron application Nuclear physics – Properties of matter and elementary particles Solid state physics – Properties of modern materials – Magnetic properties Space science Technical and power systems Environmental science, etc.

3 Neutron detection n+ 3 He → 3 H+p+0,77 MeV n+ 6 Li → 3 H+α+4,79 MeV n+ 10 B→ 7 Li+α+γ(0,48 MeV)+2,3 MeV (93%) → 7 Li + α + 2,79 MeV (7%)

4 3 He filled counter measurements n+ 3 He → 3 H+p+0,77 MeV Pu-Be neutron source PE blocks for moderation Energetic resolution: 5,5 % FWHM

5 Types of position readout in PSD Position signal readout: IndividualResistive line Delay line

6 2D PSD measurements MWPC – 2 cathode planes 1 anode plane 1D count distribution Counting response Pu-Be neutron source PE blocks for moderation

7 Examples of IBR-2 measurements

8 Thank you for your attention Special thanks to: A.V. Churakov Tz. Panteleev
