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.

CNT Transistor with Antibodies

Prof. Charlie Johnson's lab has produced new experiments demonstrating that carbon nanotube transistors (CNT) can detect minute quantities of biomarkers of diseases in less time than conventional methods.  Antibodies attached to 
CNT on a silicon chip change the electrical properties of the chip upon antibody-antigen binding hence detecting disease biomarkers.

Euclid Mission to Explore Dark Energy

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures.  Penn researchers are part of the Euclid science team.


Large Hadron Collider - ATLAS Higgs candidate event

An event captured by the ATLAS detector in the search for a Higgs boson decaying into two Z bosons, one of which goes into a pair of electrons and two muons (the two tracks shown in red). There is no way to tell if this particular event comes from a Higgs decay or simply from a background event such as one containing two Z bosons.


SDSS Galaxy Survey

The UPenn Fit Catalog provides 2-d galaxy profile fits in several visible bands using SDSS data.  Additional data collected from other sources is provided to facilitate analysis. The catalog is constructed and maintained by Professor Mariangela Bernardi and her group.
