ATLAS Transition Radiation Tracker

The Penn HEP group played a major role in the design, construction, and commissioning of electronics to read the electrical signals on each wire of the TRT. This includes both analog electronics (ASDBLR) to discriminate and shape the analog signal from each wire, and digital electronics (DTMROC) to record the signal every 3.125ns and interface with the detector read-out.

Singh Center for Nanotechnology

The newly-opened (Oct. 4, 2013) 78,000 square-foot Krishna P. Singh Center for Nanotechnology serves as Penn's focal point for nanoscience research and technology-development.  P&A's Prof. Jay Kikkawa was instrumental in the planning and provision of vital services for the new facility.

Dark Energy Studies

Professor Masao Sako uses Type Ia supernovae to study the expansion history of the universe.  The graphs show (left and middle) Hubble diagrams from a simulated 5-year Type Ia sample from the Dark Energy Survey.  The right graph shows the 95% confidence limits on dark energy parameters.

Neuroscience

Prof. Vijay Balasubramanian's research includes studies of structural and functional organization of the retina with multi-electrode arrays that record retinal ganglion cells. He also studies computational principles that underlie the organization of circuits in the early visual system.
