what did the 2010 early career award allow you to do dark matter makes up most of the mass of the universe it is believed to be made up of a yet-to-be-discovered stable heavy particle that interacts very weakly with ordinary matter there is an intense search worldwide to directly detect this particle using a variety of detector technologies due to the very weak nature of the interaction of dark matter with ordinary matter large and sensitive detectors are required for discovery the doe early career award funded my proposal to develop ton-scale highly-sensitive cryogenic semiconductor detectors leveraging infrastructure already in hand the award essentially changed the course and impact of my research work enabling my group to establish a high-performance cryogenic semiconductor detector fabrication and characterization facility this facility and the detector development efforts have allowed researchers working on the supercdms experiment to substantially improve the quality and cost of the next-generation detectors for the experiment in snolab these advances have allowed utilization of the detector technology to detect neutrinos from a reactor or the sun using a coherent interaction process similar to how dark matter interacts with ordinary matter this technology holds potential for many other applications such as nuclear non-proliferation through neutrino detection and medical imaging the award also allowed me to attract strong graduate students which has been instrumental in the success of the program scientists running these detectors hope to unravel the mysteries of the universe ranging from identifying the nature of the particles that make up dark matter to new physics in neutrino interactions about: rupak mahapatra is a professor in the department of physics and astronomy at texas a&m university supporting the doe sc mission: the early career award program provides financial support that is foundational to young scientists freeing them to focus on executing their research goals the development of outstanding scientists early in their careers is of paramount importance to the department of energy office of science by investing in the next generation of researchers the office of science champions lifelong careers in discovery science for more information please go to the early career research program the 2010 project abstract: ton scale germanium: beyond zeptobarn wimp cross‐section the currently favored explanation for the invisible dark matter that holds galaxies together is a new kind of fundamental particle: a weakly interacting massive particle (wimp) these particles may be produced and detected in high‐energy particle collisions at the fermilab tevatron or the cern large hadron collider but there are also many active searches underway to directly detect cosmic wimps interacting with normal matter the extremely weak nature of the wimp interaction dictates detectors that have extremely low naturally occurring radioactive background a large active volume (mass) of sensitive detector material to maximize statistics and a highly efficient rejection of any residual background to fully explore the possible wimp parameters we need to scale up from the current few-kilogram experiment to few-ton experiments this proposal is a three‐pronged phased approach to address all these issues through the research work of the principal investigator as a member of the cryogenic dark matter search (cdms) collaboration and the next generation proposals for 100kg‐scale supercdms and ton‐scale germanium observatory for dark matter (geodm) experiments resources: r agnese et al (supercdms collaboration) search for low-mass weakly interacting massive particles using voltage-assisted calorimetric ionization detection in the supercdms experiment physrevlett 112 041302 (2014) [doi: 101103/physrevlett112041302] ajastram hr harris r mahapatra j phillips m platt k prasad j sander jw suh and s upadhyayula cryogenic dark matter search (cdms) detector fabrication process and recent improvements nuclear instruments and methods in physics research a772 14 (2015) [doi: 101016/jnima201410043] n mirabolfathi hr harris r mahapatra k sundqvist a jastram b serfass d faiez and b sadoulet toward single electron resolution phonon mediated ionization detectors nuclear instruments and methods in physics research a855 88 (2017) [doi: 101016/jnima201702032] additional profiles of the 2010 early career award winners can be found at: https://wwwenergygov/science/listings/early-career-program the office of science is the single largest supporter of basic research in the physical sciences in the united states and is working to address some of the most pressing challenges of our time for more information please visit wwwenergygov/science sandra allen mclean is a communications specialist in the office of science sandramclean@sciencedoegov this post rupak mahapatra: then and now / 2010 early career award winner appeared first on office of science share:
