LaBr3 detector modules for Next Generation PET scanners

On the left is a schematic of adjacent modules with overlapping photomultiplier tubes while the right is a photograph of a single module with PMT's and 8-mm thick light guide.  Improvements in timing resolution for time-of-flight PET is the research of Adjunct Prof. Joel Karp in Penn Radiology.

Outreach Effort for Penn Physics and Astronomy

At the Penn Summer Science Academy (PSSA) students listen to a lecture, delivered from CERN by Professor Elliot Lipeles, on the discovery of a Higgs-like particle the day after the international announcement.

 

Science Verification Images from DES

High resolution color image of area SPT-CL J2332-5358 from the Dark Energy Survey Science Verification stage of testing of the telescope and DECam.

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.

Dark Energy Survey

The Dark Energy Survey (DES) uses a 570-Megapixel digital camera at the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in the Chilean Andes to probe the origin of the accelerating universe. Penn scientists are among the 120 scientists from 23 institutions in the US, UK, Brazil, and Germany working on the project slated for first light in Fall 2012.
