Proton beam dosimetry by CR-39 track-etched detector
Background: High and intermediate energy protons are not able to form a track in a solid state nuclear track detector (SSNTD) directly. However, such tracks can be formed through secondary particles created during primary radiation nuclear reactions in a SSNTD. Materials and Methods: The protons with primary energies of 9.6 and 30 MeV available at the cyclotron accelerator with corresponding lo...
متن کاملSimulation of a Neutron Detector for Real Time Imaging Applications
Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
متن کاملLow-voltage electroosmotic pumps fabricated from track-etched polymer membranes.
Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...
متن کاملIncorporating Amphoteric Groups in Ion Track-etched Single Conical Nanochannels
Here, we report a facile and straight-forward approach to incorporate amphoteric groups inside the single conical nanochannels. This was realized by direct chemical modification of the surface carboxyl groups with L-lysine chains whose positive and negative charges are very sensitive to the external pH. The chemically functionalised channels were characterized both theoretically and experimenta...
متن کاملFission Fragments Track- Etched Pores in Borate Glass
A study has been made to investigate the detection sensitivity of Borate Glass for the heavily ionizing fission fragment tracks. The latent damage tracks produced by fission fragments in Borate Glass, with and without Aluminium Oxide as an additive, have been studied under a high resolution scanning electron microscope. Tracks have been found and studied only in the Borate Glass samples with no...
