National Science Day celebration at RRCAT on 24th and 25th February 2024

National Science Day is celebrated in India on 28th February of each year to commemorate the discovery of the Raman Effect by Prof. C. V. Raman who was awarded Nobel Prize in Physics in the year 1930 and Bharat Ratna in 1954. RRCAT celebrated the National Science Day on last Saturday and Sunday of February i.e. on 24th and 25th February by holding an open house for the school and college students, teachers, family members and guests of RRCAT staff and invitees from public. The theme of this year’s National Science Day was “Indigenous Technologies for Viksit Bharat”. .

On Saturday, February 24, 2024, students of Class XI and teachers from schools in and around Indore, were invited for a full day visit. More than 1000 students and teachers invited from 70 schools of Indore and nearby places visited RRCAT. The program started with an address by Shri Purushottam Shrivastava, Officiating Director, RRCAT on the basics of Raman Effect and working principles of accelerators and lasers, which are the main areas of research and development at RRCAT. His lucid explanation in simple Hindi language was very much appreciated by the students and the teachers. A few small movies depicting importance of hygiene and cleanliness were also shown to students and teachers under “Swachcha Bharat Abhiyaan”.

Special arrangements were made for the Hearing and Speech impaired students invited from special schools to participate in the celebrations accompanied by interpreter-teachers. Officiating Director, RRCAT, along with senior members of organizing committee, interacted with about 50 special students in a separated interactive session and tried to address their queries with the help of interpreter-teachers. The students participated actively and enjoyably in this interaction session.

After the address, all the students were taken to exhibit places at laboratories and RRCAT Convention Centre, in organized groups, under the guidance of RRCAT volunteers. There were working exhibits on lasers like use of light and lasers for biomedical applications, demonstrations on applications of lasers like: laser cutting and marking, laser additive manufacturing and Nd:YAG and fibers lasers etc. To explain some basic science concepts, special experiments had been set up like Raman effect, Michelson interferometer, Schilieren imaging, total internal reflection, experiments with liquid Nitrogen, artificial cloud formation, laws of motion, gas laws, conservation of momentum, change in physical properties of materials at low temperature, etc. To explain some technology applications, live demonstration with models of meglev train based on linear induction principle, Agni Rakshak, CNC machining, induction heating, glass blowing techniques etc. were shown. Videos on Indus Synchrotrons and their uses, development of SCRF cavities, indigenous 10 MeV linear accelerator, thin film coated optics, optical diagnosis of cancer, laser additive manufacturing, laser cutting, detection of RF and Microwave signals, demonstration of human height measurement system using parallel plate capacitor etc. were shown.

About 37 exhibits related to technologies of accelerators, lasers, cryogenics, superconductivity, RF and Microwave, magnets, along with demonstration of Fire & Safety aspects were set up at RRCAT Convention Centre and in different laboratories to explain the scientific and technical activities of RRCAT as well as to demonstrate a few concepts in basic sciences and engineering.

Important scientific achievements and in-house technology developments were showcased, with emphasis on “Make in India”, with the help of illustrated posters, working models, and actual components. These included instruments like TuBerculoScope, Raman Probe Oncodiagnoscope, Agni Rakshak, laser micro welding machine for brachytherapy sources and development of laser technologies related with maintenance of Indian PHWRs, diode pumped laser marker, technology for LN2 based REEFER, SCRF cavity, superconducting corrector magnets, solid state RF amplifier, high stability power converters, crystal growth, Fiber Bragg Grating (FBG) sensor, UV-NIR laser beam visualizer etc. which greatly enthused the young visitors.

The overall response of the students and teachers was very enthusiastic showing keen interest in the exhibits and had lively discussions with the RRCAT officials. Exhibits like demonstration of laser cutting, magnetic levitated train, shaping glass using glass blowing technique, artificial cloud creation by liquid nitrogen and live demonstration of fire-fighting created a vivid impact on young minds and earned applause from students, teachers, family members of staff and guests.

An “Ask-a-Question” event was organized for the students with an aim to create an opportunity for free discussion between these young minds and the working scientists. Several RRCAT scientists interacted with the students encouraging them to ask questions. The discussions ranged from questions arising out of the exhibits at RRCAT for science day to basic scientific concepts. The event also encouraged the accompanying teachers to discuss their problems in teaching particular concepts of science. Participation prizes were also given to curious students. The specially-abled students also visited various laboratories and took part enjoyably in “Ask a Question” event with great enthusiasm.

All the students and accompanying teachers were offered refreshments and lunch in the morning and noon respectively. Souvenir caps were also distributed to all the students and teachers. Buses were arranged for movement of the students to various exhibits and labs. The overall response of the students was extremely enthusiastic as demonstrated by the number of queries they put in during the visits to the exhibits and at the “Ask-a-Question” event. They went back full of admiration for the scientific activities being pursued by DAE in general, and RRCAT in particular. They were also impressed by the cleanliness, greenery and lakes in the RRCAT picturesque campus.

On Sunday, February 25, 2024, family members and guests of RRCAT staff, college students, and invitees were given opportunity to visit RRCAT laboratories. More than 2800 persons including about 500 college students and teachers visited the laboratories and expressed their happiness on getting an opportunity to learn about the important R & D activities being carried out at the Centre.

This year more than 200 schools and 30 colleges were sent invitation through a website specifically developed for this purpose. The website served as a single source point for broadcasting information like important dates, reporting time, food availability and also received date like name. ID details and photos of the students and teachers etc. to and all the schools and colleges.

The whole event was managed by Public Outreach Committee, RRCAT under keen supervision of Dr. S.V. Nakhe, Director RRCAT with Shri Rajesh Arya as the Convener and Dr. S.K. Majumder as Co-convener for the event. The committee had made quite elaborate arrangements for the event with the help and enthusiastic cooperation of a large team of volunteers, exhibitors, administrative staff, and security personnel. The event was covered by different major national and state level newspapers.
