Abstract

Multiwire Proportional Counter (MWPC), a particle studied under this project is an indispensable part of all nuclear physics experiments involving the study of compound nucleus and fission fragments. The work done under this project involves the fabrication, assembly and testing of a MWPC. The experimental work has been done at Inter University Accelerator Center (IUAC), New Delhi. The MWPC fabricated at IUAC had an active area of 16x11 cm2. Timing resolution and gain of the fabricated MWPC was made to improve over that of already available MWPCs at IUAC by reducing the anode wire pitch and using a ten micrometer diameter wire for anode frame. The fabricated MWPC was thoroughly tested with an alpha source and it was observed that the detector could handle heavy count rate exceeding 20 KHz without any breakdown. Fabricated MWPC was also used in a nuclear physics experiment in the NAND experimental set up of IUAC to extract information about mass, kinetic energy and angular distribution of fission fragments. All the detailed investigations done with the detector were part of the M.Sc. Dissertation work of the first two authors. During under graduation and post-graduation, students study about proportional counters with emphasis on their construction and basic principle of operation. However, this project work provided the first two authors with a unique opportunity of getting a practical experience on how these proportional counters are fabricated and their importance in the field of nuclear physics. Thus, project based learning leaves a larger impact on the mind of the students as far as understanding of concepts of science is concerned Introduction A multi wire proportional counter is simply a gas filled wire chamber consisting of a large number of anode wires stretched in a plane for position measurement. The original motivation of developing such detectors came from the need to track particles in high energy physics experiments. The wire chambers, thus developed worked amazingly well and helped scientists make grea discoveries at particle accelerators. Although these chambers are still used in some laboratories, but since the advent ofhigh resolution silicon detectors their utility has somewhat diminished. Fig.1 shows the sketch of a typical multi wire proportional chamber [1]. The closely spaced thin anode wires are stretched in a plane that is midway between two cathode planes. The cathodes are kept at negative potential with respect to anode wires that are kept at ground potential. Each of the anode wires acts as an independent proportional counter and must therefore be read out independently [2]. For full article .... Visit Site ...www.ijsrd.com

IJSRD Conference: (Information and Communication Technologies) & IoT (Internet of Things)

“NATIONAL CONFERENCE ON ICT”

Transforming ICT to IoT

In association with

IJSRD– International Journal for Scientific Research & Development

SAL Institute of Technology & Engineering Research, affiliated to the Gujarat Technological University, Ahmedabad., is organizing 1-day event named “National Conference on ICT”  on 20th January 2016 in association with IJSRD.
The conference aims to provide an opportunity to teachers/mentors/ educators and students to acknowledge, celebrate and showcase research being carried out by students by enabling them to engage with the wider communities to exchange ideas and share intellectual activity through paper presentations sessions. The event shall feature research papers presentations by eminent educators and students from all over India in the field of ICT (Information and Communication Technologies) & IoT (Internet of Things).
