Học bổng thực tập tại Hàn Quốc và Đài Loan

1. GNSS and ionosphere:

Description:

This program aims to provide a comprehensive introduction to the Global Navigation Satellite System (GNSS) and its application to ionospheric research.

Topics to be covered:

◦ Principles of GNSS and its applications (e.g., coordinate and time system, satellite orbits, GNSS observables, estimation procedure)

◦ Monitoring the ionosphere using GNSS (e.g., basics of the ionosphere, analysis of GNSS TEC, and comparison with global model results)

◦ GNSS data processing using Bernese 5.0 Software (Basic run and estimation of TEC)

A student will work on these research topics with professional scientists at KASI and engage in interactive tutorials and project-based activities. A student will also have the opportunity to visit KASI observational facilities in which they can improve their understanding of the research.

At the end of this program, students may give a short oral presentation of their results and write up a summary of their activities.

2. Space-based magnetometer

Description:

The aim of this program is two-fold:

◦ Comprehensive introduction to the space-based magnetometer: based on interactive lectures and workshops

◦ Spacecraft control practice: at a ground station for a KASI CubeSat mission, ‘SNIPE’

A student will work on these research topics with professional scientists and engineers at KASI and engages in a series of interactive tutorials and practices with KASI facilities. At the end of this program, students will be encouraged to give a short oral presentation and document a summary of their activities.

3. Characteristics of Superconductor Nanowire Single Photon Detectors

Description:

The superconductor nanowire single photon detector (SNSPD) is the new development project in ASIAA. The goal of this project is to develop SNSPD systems in 5 years for quantum communication systems. We plan to use the in house NbN superconductor technology to develop the SNSPDs. We have just set up the testing system for the SNSPDs and the student joins this project will join the testing of SNSPDs and learn the methodology for the characterization and design of the SNSPDs.

4. BURSTT front end testing and deployment

Description:

To search for FRBs, ASIAA plans to set up a 256 element array in the Fushan Botanical Garden as the main array for the BURSTT (https://www.asiaa.sinica.edu.tw/project/burstt.php) project. It’s a good opportunity for students to get involved in front end (antennas, LNAs, etc) testing and deployment. Students would learn how to assemble and test various front end components in lab and then deploy them in the field. Thereby they would also get a sense of how radio receivers work.

5. Performance verification of FP2 wheels mechanism

Description:

METIS, named after the Greek goddess of wisdom, will be one of the first-generation ELT instruments. It will cover the infrared wavelength range and make full use of the giant, 39-metre main mirror of the telescope to study a wide range of science topics, from objects in our Solar System to distant active galaxies. To achieve diffraction-limited performance, METIS will use a single-conjugate adaptive-optics (AO) system to compensate for atmospheric turbulence. The instrument consists of two separate units, one for the imager and another one for the spectrograph. It is entirely encased in a cryostat to maintain the stable low temperatures required for good performance at mid-infrared wavelengths. The wavelength coverage ranges from 3 − 13 μm for the imager and 3 − 5 μm for the IFU spectroscopy. The expected field of view is ~10” for the imager and <1” for high resolution IFU spectroscopy. The spectral resolution has several modes. The low-resolution mode for a long-slit spectroscopic observations with R~400 at N-band, R~1500 at L-band, and R~1900 at M-band. The high-resolution mode is for IFU observations with R~100,000 at L, M bands.

One major participation of ASIAA is the development of the Cold Front Optics (CFO). More specifically, ASIAA involves in the design and fabrication of the Pupil plane 1 (PP1) and Focal Plane 2 (FP2) filter wheels inside CFO…

The potential summer project contains the following works:

– Help setting up the test equipment, including the integration of FP2 wheels, the preparation of cryogenic chamber, and the calibration of the laser probing system, etc.

– Operating the test equipment and conducting practical measurements. If possible the student can participate the data analysis.
