No full textWe report here the growth and characterization of non linear single crystals β BaB2O4 (BBO) which is an interesting material for second harmonic generation. Single crystals were grown from Na2O-B2O3 solutions using the top seeded solution growth method. The experimental set up included a Nd:YAG, Q switched, focalised with a cylindrical lens on the samples. Efficiency up to 40 % were obtained using 6 mm long crystal
Characterisation of LSO:Tb scintillator films for high resolution X-ray imaging applications
No full textWithin the framework of an FP6 project (SCINTAX)1 we developed a new thin film single crystal scintillator for high resolution X-ray imaging based on a layer of modified LSO (Lu2SiO5) grown by liquid phase epitaxy (LPE) on a dedicated substrate. In this work we present the characterisation of the scintillating LSO films in terms of optical and scintillation properties as well as spatial resolution performances. The obtained results are discussed and compared with the performances of the thin scintillating films commonly used in synchrotron-based micro-imaging applications
