The Best View in Philadelphia

The University of Pennsylvania recently finished their newest addition to the campus, Penn Park, which adds a brilliant contrast to the Philadelphia skyline and gives multiple sports teams a new place to practice and engage in athletics.

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.

The SNO+ Experiment

SNO-plus is a multi-purpose neutrino experiment, located 2km underground in an active nickel mine in Sudbury, Ontario. It is a large liquid scintillator experiment, currently under construction, inheriting most of the detector hardware from the successful SNO experiment.  The Penn SNO-plus group is led by Professor Josh Klein.


Air-fluidized grains

Spatiotemporal heterogenous dynamics in air-fluidized grains near jamming. The colors represent the average speed over a time interval large enough for grain-sized rms displacement. The most mobile grains are in red, the least are in blue, across the rainbow. Note the stringy correlations of the mobile grains in red. From the lab of Prof. Doug Durian.

DES First Light

One of the first images from the DECam (the half-gigapixel camera of the Dark Energy Survey) showing the barred spiral galaxy NGC 1365. Penn faculty and staff play a prominent role in leading the DES effort.
