1 Call 18203/2016 per il finanziamento di 6 progetti per giovani ricercatori High performance 3D CadmiumZinc-Telluride spectro-imager for X and gamma-ray applications 3CaTS Nicoletta Protti, National Institute of Nuclear Physics INFN, Pavia Unit

2 Specific Objective: real-time 10B dose measurement in BNCT (Boron Neutron Capture Therapy) BNCT is an experimental form of binary radiotherapy based on the exothermic (Q = 2.79 MeV) nuclear reaction of the stable isotope 10B Lethal damages in cancer cells are produced if enough 10B is selectively loaded by the tumour (secondary particle ranges < 10μm)

3 General problem in BNCT dosimetry BNCT celllevel selectivity and biological effectiveness thermal neutron flux distribution at tumour site B microscopic distribution at irradiation time 10 dd(x,y,z) nb10(x,y,z) (x,y,z) dv Monte Carlo-based Treatment Planning Systems (TPS) validated through TEphantom measurements PET 10 irradiation B infusion blood samples and ICPS

5 3CaTS goal To develop and build an innovative fully functional highly segmented prototype of a CdZnTe (CZT) solid state photon detector to prove and evaluate its perfromance as room temperature spectrometer with 3D spatial resolution capabilities suitable for different spectroscopic imaging applications in the range from few tens of kev up to 1 MeV medical imaging fine spectroscopy for fundamental physics hard-x and soft- rays astronomy

10 Compound semiconductor detectors By selecting the physical properties (band gap, atomic number, density, etc...) through the material growth process it is possible to tailor and customize the compound semiconductor to the specific application of interest. Presently, Cadmium-Zinc-Telluride (CZT) is receiving increasing attention for the development of X and gamma ray detectors operating in the energy range from few tents of kev up to 1 MeV high Z high detection efficiency, favored photoelectric effect over Compton one wide band gap leakage current < na, room temperature operation charge carriers trapping, 2-3 o.m. difference in between electrons and holes degradation of energy resolution and operative limits at high count rates

11 Compound semiconductor detectors Main drawback of CZT as radiation detection material: (1) challenging growth technology to deliver big (1-2 inches diameter) detector-grade crystals and (2) low carrier mobility (in comparison with traditional Si and Ge semiconductor detectors) (1) Boron oxide encapsulated vertical Bridgman technique (state of art) to prevent crystal-crucible contact Zone 3 TC3 TC2 Zone 2 TC1 Zone 1 detector-grade large single grain crystals up to 3 inches very low dislocation density (< 104 cm-2; minimum value of cm-2)

12 3CaTS proposed detector 3D-CZT sensor: 20x20x5 mm3, Limited number of read-out channels (30) but still high segmentation. planar transversal field (PTF), orthogonal strip electrodes ( ), contact pitches of 2 mm (cathode) and 1 mm (anode, 1 central read-out strip + 4 drift strips/side) Bottom face face(*) (*) Bottom Top face face Top -rays (*) drift strips not reported -rays PPF PTF

13 3CaTS proposed detector 3D-CZT sensor: 20x20x5 mm3, planar transversal field (PTF), orthogonal strip electrodes ( ), contact pitches of 2 mm (cathode) and 1 mm (anode, 1 central read-out strip + 4 drift Bottom face face(*) (*) Bottom Top face face Top -rays (*) drift strips not reported -rays photon irradiation strips/side)

14 3D position sensing CZT spectrometers CZT spectrometer with spatial resolution in three dimensions (3D CZT) are a new frontier. The advantage offered by 3D reconstruction of both the photon interaction position and the single energy deposition are fundamental for applications requiring high detection efficiency even in the Compton regime (> 100 kev) and a uniform and fine spectroscopic response throughout the sensitive volume (correction for signal variations due to charge trapping and material non-uniformity).

15 Imagin reconstruction software Proposed energy range: few tens kev up to 1 MeV, with special emphasis around 500 kev Compton interaction probability in CZT crystal 4 times that of photoelectric effect Development of a software for image reconstruction able to take advantage of the Compton events inside the 3D spectrometric sensor: - co-registration of interaction position and deposited energy per hit => - imaging reconstructed by analysing the distribution of the intersections of the incidence cones of Compton kinematic and through the use of statistical methods (e.g. maximum likelyhood) and the results of Monte Carlo simulations (GEANT4) Through this tool we could drastically improve the detection efficiency and the wide angle response of the detector at high energy, allowing the implementation of reliable and effective reduction of noise.

16 3CaTS proposed detector 3D-CZT sensor: 20x20x5 mm3, planar transversal field (PTF), orthogonal strip electrodes ( ), The 3D spatial detection capability requires fast electronics able to perform pulse detection and trigger time tagging with high resolution (< 1ns), allowing time coincidence measurements in short time coincidence windows. contact pitches of 2 mm (cathode) and 1 mm (anode, 1 central read-out strip + 4 drift strips/side) Bottom face face(*) (*) Bottom Top face face Top -rays (*) drift strips not reported -rays Digital approach: detector output signal from CSP directly fed into fast digitizers and processed by digital algorithms Other advantages: - customable filters and procedures - stability and reproducibility - off-line and real-time analysis - PSA to minimize incomplete charge collection distortions, pile-up, recovery signal through DOI information and charge sharing - reduction and control of dead time effects

By combining the effect of the hole trapping with the single polarity charge sensing ability, we can obtain information on the radiation interaction depth through the Ratio R between the collected charges Qcathode and Qstrip. The depth information (R) can be used to correct the anode strip signal fluctuation caused by the electron trapping and the non ideal weighting potential effect
