Research


Mu2e Collaboral Project

Jun 2010 - Present

We design and test a Time-to-Digital Converter (TDC) with a FPGA for the muon tracker in the mu2e project. The FPGA will record the time of hits left by charged particles as they traverse the detector, and it needs to do it with a precision of about 1 nanosecond. Our group also works on some software development for the experiment, including simulations and reconstruction code.

Over the summer, I worked with a couple electrical engineers and learned how to program the FPGA in VHDL. I also developed a data acquisition program (DAQ) on LabWindows in C and made some cables for our system. Recently we have finished prototyping a PCB for a scheduled radiation test. While waiting for the test, I am currently implementing additional features on DAQ such as error counter and exploring LabWindows in general.

 
 

Distributed Energy Resources

Feb 2010 - Sep 2010

In Distributed Energy Resources (DER) group, we study customer adoption patterns of microgrid technology through assessments and analysis with the Distributed Energy Resources Customer Adoption Model (DER-CAM). I helped with data collection and coding the data processing unit of DER-CAM. I also spent majority of my time there working on the website.

In addition to my participation in DER group, I also did some technology invesigation with the DC Power group and researched on existing DC standards for potential residential and commercial DC system development.
