ALL the 2022 Summer Events in Taiwan are Suspended due to Constraints from COVID-19 Pandemic. The Host Group plans to organize the Events again in Summer 2023. Refer to the PIRE-GEMADARC Home Page for Alternative Programs in 2022.

Undergrad Research Experience

Undergrad Research Experience

 
 

The PIRE-GEMADARC program includes research position of its members at another partner institutes. Students with non-physics and physics majors are expected to station for some time in summer 2022 at the Institute of Physics, Academia Sinica to participate in research projects supervised by its senior faculty researchers of the particle physics group, and coordinated by the TEXONO program.

Participating students are expected to arrive on or before May 19, 2022, and join the Summer School and Collaboration Meeting. Individual research projects will start on May 30 and last till at least July 12. The program can be extended depending on individuals’ plans, and to as further as August 31, 2022.

Coordinators for physics majors are Prof. Joel Sander (joel.sander@usd.edu),U South Dakota, USA and Prof. Mary Kidd (mkidd@tntech.edu),Tennessee Technological University, USA. Coordinator for non-physics major is Prof. Brianna Mount (brianna.mount@bhsu.edu),Black Hill State U, USA.

There activities are independent of the PG2022 Summer School and Collaboration Meeting. This page serves as a platform for effective information exchange. Information will be continuously added and updated.

      1. Characterization and Pulse Shape Analysis of Germanium Detectors with sub-keV Sensitivities

Faculty Supervisor:   Dr. Henry T. Wong

Germanium detectors with sub-keV sensitivities have been used in the studies of low energy neutrino physics as well as in dark matter and axion searches. We will perform characterization and test pulser calibration measurements with the latest upgrades of these detectors. We will also further advance pulse shape analysis techniques to differentiate between physics events located at the bulk or surface of these detectors, as well as electronic noise events near electronic pedestal threshold.    

 

       2. Searches of Beyond-Standard-Model physics with Germanium Detectors with sub-keV Sensitivities.

Faculty Supervisor:   Dr. Henry T. Wong

Low background data with germanium detectors with O(100 eV) threshold have been taken by the TEXONO experiment at the Kuo-Sheng Reactor Neutrino Laboratory, and by the CDEX experiment at the China Jinping Underground Laboratory. They are valuable to be used in searches for various scenarios of physics beyond Standard Model, especially those with signatures requiring good threshold and/or low threshold. We will perform simulation studies, data analysis and derivation of physics constraints on some of these models.

 

      3. Development of Resistive plate chambers

Faculty Supervisor:  Dr. Wen-Chen Chang

Resistive Plate Chambers (RPCs) are gaseous parallel-plate detectors with good spatial resolution and a superb time resolution comparable to that of scintillators. Since the cost of its manufacture is relatively low, RPCs have been the popular choice of the charged particle tracking and particle identification. We will develope a prototype of RPCs with the new features of adopting the plate soft glass and replacing the carbon sheet by the PCB copper strip. With the success of these new approaches, we look forward to significant improvement in the efficiency and reliability of detector assembly.

        

      4. Design of muon-identification detector

Faculty Supervisor: Dr. Wen-Chen Chang

To carry out the measurement of exclusive Drell-Yan processes in E50 experiment at J-PARC, Japan, we are going to build up a muon-identification (muID) detector. This detector is composed of tracking device for charged particles, and stopping materials for hadrons. The design is to be optimized in term of stopping power of hadrons, good rejection of decay-in-fly mesons, as well as the proper penetration of muon tracks. We will study the design of muID detector using the GEANT4 simulation package.

 

       5. Simulating collective flavor conversions of neutrinos

Faculty Supervisor: Dr. Meng-Ru Wu

Neutrinos play critical roles in explosive and neutrino-dense astrophysical environments such as core-collapse supernovae and binary neutron star mergers. Earlier studies revealed that certain collective oscillation phenomena should occur in the central regions of these events and may largely affect several related and important physical processes and the detection of supernova neutrinos. However, understanding of these collective phenomena remains elusive due to the nonlinear and anisotropic nature of the problem, and requires advanced computational modeling. In this project, we will aim to learn and improve the simulation code "Collective oscillation simulation engine for neutrinos (COSEnu)" which deals with the multidimensional transport of dense neutrinos gas, and explore how different physics inputs and assumptions affect the outcome of collective neutrino flavor oscillations.

 

       6. Radiation detectors for medical applications

Faculty Supervisor: Dr. Ming-lee Chu, Dr. Chih-hsun Lin

In high-energy experiments, several types of detectors are used to detect particle trajectories, energies and speeds. Those detectors also have many medical applications, including imaging in medical diagnosis and assurances in radiation therapy. In this summer research session, we will show you the principle of different types of detectors and their medical applications. We will also provide hand-on training to operate at least one type of detector to measure physics quantities.

 

       7. Application of GPU and Machine Learning for proton therapy and biomedical imaging analysis with Big Data

Faculty Supervisor:  Dr. Eric Yen, Dr. Chih-hsun Lin

Adopting technologies for nano-second time scale and micrometer spatial scale gamma-ray imaging over a large detection area developed in experimental particle physics to collect big data in real time during proton therapy and integrating with artificial intelligence analysis of on online and offline data with fast GPU computing, the therapy can be personalized to improve the efficiency and quality of treatments significantly. The study aims to accelerate the simulation by GPU computing based on Geant4. We also hope to build up a prototype to be able to learn from more test datasets progressively in considering the beam parameters as well as personal characteristics.

 

       8. Gravitational Physics - Systematic error study with synchronized gravity field calibrators

Faculty Supervisor: Dr. Yuki Inoue , National Central University & Academia Sinica

The systematic error of calibration instruments will determine the science limit of future gravitational wave observation. To improve the accuracy of measurement, we are developing the new type calibration system with dynamic gravity gradient, so call gravity field calibrator. Recently, we develop the large and small type detector. By synchronizing two systems, we can verify the systematic error of observation. In this course, we will develop the automatic synchronization system with digital feedback system and estimate the expected systematic error with measured data.

 

      9. Gravitational Physics - Thermal noise study for Cryogenic Gravitational Wave detector 

Faculty Supervisor: Dr. Yuki Inoue , National Central University& Academia Sinica

The improvement of the gravitational wave sensitivity is essential for exploring of fundamental physics. One of the serious noise of current gravitational wave observation is thermal noise with Brownian motion.To mitigate the thermal noise, we need to reduce the temperature and mechanical loss of optical system. In Academia Sinica, we have developed the cryogenic system. By using the cryogenic measurement system, we will measure these parameters. Based on the measured parameter, we will estimate the expected sensitivity of the gravitational wave strain. In this course, we will teach the basic measurement method and analysis for the next generation gravitational wave observation.
