Collaborative Study : Post growth processing of CdZnTe elements for gamma-detector applications

Please send an E-mail to: sgm@igcar.gov.in	Closing Date : 15.05.2024
Theme	CdZnTe based gamma-ray detectors are preferred in nuclear and medical industry owing to its room temperature operation and better efficiency compared to HPGe detectors which requires liquid nitrogen for its operation. The charge transport and the gamma detection efficiency depends not only on the purity of the grown crystal but also on the surface properties of the crystal which is mainly determined by the post processing procedures like cutting, dicing of ingot, mechanical or chemo-mechanical polishing, surface passivation and electrode preparation. In this work it is proposed to develop post growth processing techniques for production of CdZnTe elements with minimum leakage current for gamma-detector applications.
Scope of the Study	The main objective of the study is to develop a systematic methodology for the post processing of CdZnTe elements with better surface properties resulting in minimum leakage current which in turn would increase the gamma detection efficiency. Imaging of the polished crystal for mapping of segregation of Tellurium and dislocations using IR microscope Improving the crystalline quality by post-growth annealing processes under Cd/Zn/Te rich conditions and in a hydrogen atmosphere. Passivation of electrically active surface defects like dangling bonds, high conductive Te-rich layer, and impurities caused by chemo-mechanical polishing to decrease the surface leakage current. Deposition of gold chloride contact by electroless method to minimize the formation of oxides at the metal-semiconductor interface to produce better Ohmic behavior Studying the I-V characteristics of the detector material after each step to identify optimum characteristics.
Expected Expertise	Academic / Research Institutes with expertise in the field of IR imaging of polished surfaces, annealing, gold electroding, wire contact and measurement of I-V characteristics.

Collaborative Study : Development of neutron shielding material using borate and Gd₂O₃ nanoparticles.

Please send an E-mail to: vidya@igcar.gov.in	Closing Date : 17.05.2024
Theme	The shielding of neutron is a challenging task due to the nature of its interaction with matter. It can travel large distances through most materials without being scattered or absorbed. Concrete is of the most widely used shielding material in nuclear reactor. Radiation shielding concrete can be used to attenuate both neutron and gamma rays. High density concretes are largely used for shielding against ionizing radiation in nuclear installations, medical units or wherever radiation protection is needed. The shielding ability of concrete can be improved using cement based composite materials.
Scope of the Study	The study deals with development of neutron shielding material using borate and Gd₂O₃ nanoparticles. Following are the objectives of the study: To utilize salts of Boron and Gadolinium as additive mixtures in concrete for neutron shielding studies using Am-Be. Optimization of steel slag content in concrete as both fine and coarse aggregate as per Bureau Indian Standards (BIS) Code no: 10262-2009 To study the variations in neutron shielding properties of the concrete prepared over long term exposure of neutron shielding. Monte Carlo simulation for the neutron shielding studies. Cost benefit analysis of the proposed concrete mixes vis a vis conventional concretes used in nuclear industry To identify the end use/application of the developed concrete
Expected Expertise	Academic / Research Institutes with experience and expertise in new shielding material development towards shielding of gamma and neutron.

Collaborative Study : Development of Indian Standard Phantoms (Knee and Skull) for in-vivo monitoring

Please send an E-mail to: vidya@igcar.gov.in	Closing Date : 24.05.2024
Theme	In the case of undesirable radiation exposure, Internal exposure can be estimated by in-vivo monitoring and usually requires realistic calibration phantoms. Presently, available phantoms are of international standard and do not represent the Indian population, which results in dose estimation errors. Additionally, the unavailability of radionuclide-incorporated phantoms necessitates the development of Indian standard phantoms (ISP). ISP (Knee and skull) are required for bone surface-seeking radionuclides (Eu, Am, Pu) estimation and are fabricated using mould developed by rapid prototype method and bone tissue equivalent material.
Scope of the Study	The study deals with the Development of Indian Standard Phantoms (Knee and Skull) for in-vivo monitoring. The following are the objectives of the study: Fabrication of mould for knee (bones patella + femur, tibia, and fibula) using rapid prototype method and MRI images Fabrication of the midshaft of the human leg, including a polyurethane shell that simulates human muscle and removable bones patella + femur, tibia, and fibula Fabrication of skull mould by rapid prototype method Fabrication of radionuclides (Am²⁴¹ and Eu¹⁵²) incorporated skull and knee phantoms using knee and skull mould and in-house developed bone tissue equivalent material
Expected Expertise	Academic / Research Institutes with experience and expertise in the development of moulds using rapid prototype methods

Collaborative Study : Development of Automated Defect Recognition system for radiographic inspection of Castings

Please send an E-mail to: vidya@igcar.gov.in	Closing Date : 22.05.2024
Theme	Cast products of various complex geometries are being used in various components such as Master Slave Manipulator etc. in nuclear plants. All castings shall be 100 % radiographed to ascertain defects such as Gas holes, Shrinkage, Inclusions, Hot tear etc.,. Review of casting radiographs in comparison with ASTM std reference radiographs is quite laborious, time consuming and there is a possibility of missing flaws due to fatigue of the inspector.

Scope of the Study	This study deals with recognition of various flaws in casting radiographs, extracting the various features and comparing the same with ASTM reference casting radiographs for the acceptance limits ( Category & Severity of flaws) Following activities needs to be included : Collection of production casting radiographs with various flaws to train the AI. Digitization of production casting radiographs with different flaws. Development of an AI algorithm for recognizing various flaws from digitized radiographs, sizing and evaluating the flaws online with ASTM Reference casting radiographs. GUI for the display of output of the diagnosis (both online and offline) These algorithms should be loaded in AI processor and should be executable in a device. Storage of QA cases and easy retrievability of data
