Title: Reconstruction of Air Shower Parameters for the GRAPES-3 Experiment
Project Guide: Prof. Sunil K. Gupta
Dissertation Project towards partial fulfillment of Master’s degree.
Developed a ROOT based framework to extract, read and fit the data using the lateral NKG function.
Preliminary investigations showed that the program developed was found to be much more optimized than the present algorithms being used.
Obtained first-hand experience in handling data and implementing the codes off of remote high-performance computing clusters.
Developed a deeper understanding of how to classify and distinguish Hadronic and Îł-induced air shower arrays using a combination of Plastic Scintillators and Proportional Counters in specified configurations respectively.
ch6_7.pdfThe image on the left shows a snapshot of the GRAPES-3 Experimental array set up in Ooty. The Figure on the right summarizes the results obtained from the optimization code which showed that implementing the Minuit2 algorithm in our code for NKG Fitting is indeed advantageous due to it's speed improvements. Considering that the present data collection rate is around 3 million events a day, that equates to a reduction in the computation time of ~84 hours required for analysis of just a single day's worth of events!
NOTE: All computation was carried out on a high performance supercomputing cluster at TIFR.

Title: Impact of Charge Trapping on the Energy Resolution of HPGe detectors for Rare-Event Physics Searches
Project Guide: Prof. Dongming Mei
Main goal of the project was to study the effect of deep-level trapping within Ge-detectors which are caused due to the impurities that are present within the crystals used.
Co-developed a theoretical model to estimate various charge trapping parameters associated with planar HPGe detectors.
Using the above model and data available from 9 planar HPGe detectors which had been fabricated at the University of South Dakota(USD), calculated the associated parameters for each detector to assess their overall performance, and found an upper impurity level limit below which no deep-level trapping is observed.
Additionally, also had some hands-on experience with all the steps involved in the various stages of detector development, right from the initial zone refining and crystal growth processes all the way to the fabrication of the Planar HPGe detectors.
Studies presented in the PIRE-GEMADARC collaboration meeting held on August 2019 and are in the final stages of publication in the Journal of Physics G: Nuclear and Particle Physics.

Title: Simulations and Studies of Novel Detectors for the Detection of WIMPs
Project Guide: Prof. Venktesh Singh
Was involved in the development of 2 novel Detectors to detect rare physics events.
Carried out Field Simulations within a Point Contact Germanium detector and A Spherical Gas detector for different parameters of the respective detectors.
Optimised various parameters like size, shape and impurity concentrations so as to ensure optimal field variation in order to carry out internal amplification of signals generated by rare physics events.
Was involved in the initial setup of the electronic circuitry responsible for future operation of the spherical gas detector.
Studies presented by Lab mate in the PIRE-GEMADARC collaboration meeting held in July 2018.

Title: Automated Detection and analysis of Sunspots
Project Guide: Prof. K.M Hiremath
Created an automised Python routine for analysis of solar white light images from Kodaikanal Solar Observatory.
Learnt about the various advantages of measuring different parameters of the Sun and its applications in our everyday life.
Learnt about the various modules and processes involved during the course of writing the code in python.
Report 2017.pdfThe Main Goal of the Project was to write a phyton routine which would automatically scan the FITS Images of the Sun and calculate the ratio of the areas of the Umbra/Penumbra of numerous sunspots throughout the Sun and analyse it's variation over the years. The Figure on the left shows an example of the distinguishing factors between the 2; The corresponding summer report is attached on the right.
