PULSE SHAPE DISCRIMINATION CHARACTERISTICS OF STILBENE CRYSTAL, EJ-299-33 AND Li LOADED PLASTIC SCINTILLATORS FOR A HIGH RESOLUTION CODED-APERTURE NEUTRON IMAGER

چکیده
Pulse shape discrimination performances of single stilbene crystal, EJ-299-33 plastic and Li loaded plastic scintillators have been compared. Pulse Gradient Analysis pulse shape discrimination algorithm has been tested for each scintillator sample, assessing their neutron/gamma separation. In this study each scintillator sample was irradiated with a Cf neutron source and, a real-time fast digitiser was used to collect the data. The figure-of-merit was utilised to compare the discrimination quality of the tested scintillator samples.

متن کاملSynthetic aperture imaging using a Lagrange based filtering technique.
Synthetic aperture imaging using a catheter based, circular phased array providing high resolution, dynamic focusing has been explored. Due to the high input impedance and low signal-to-noise ratio (SNR) of a classic single element synthetic aperture system, multi-element synthetic aperture processing has been proposed with SNR improvement of about 8 dB for a 33 element aperture. Reconstruction...

An immunofluorescence assay was used to detect E-cadherin and N-cadherin expression in infiltrative bladder cancer tissues, and immunofluorescence and western blot analysis were used to detect E-cadherin and N-cadherin expression in hu...
متن کاملFrom modeling to hardware: an experimental evaluation of image plane and Fourier plane coded compressive optical imaging
Computational imaging based on compressed sensing (CS) has shown potential for outperforming conventional techniques in many applications, but challenges arise when translating CS theory to practical imaging systems. Here we examine such challenges in two physical architectures under coherent and incoherent illumination. We describe hardware alignment protocols that can be used to optimize syst...
