========================================================================= "Solar Wind Charge eXchange and the DXL mission" Prof. Massimiliano Galeazzi Department of Physics, University of Miami, USA When: Wednesday, 19 October 2016 at 2:00pm Where: 2nd Floor Seminar Room Solar Wind interacts with the interstellar neutrals via charge exchange mechanism to produce spatially and temporally varying x-rays making it difficult to separate from other diffuse sources. The Diffuse X-rays from the Local Galaxy (DXL) mission is a NASA sounding rocket mission to measure the spatial signature of Solar Wind Charge eXchange (SWCX) and separate it from other sources of diffuse X-ray emission. The mission uses large area proportional counters and was able to separate the SWCX contribution from Local Hot Bubble emission, measuring the SWCX compound cross section with He. So far the DXL payload has been successfully launched twice from White Sands Missile Range in New Mexico and a third launch is scheduled for 2018 from Poker Flat, Alaska, to measure the compound cross section with H. In this talk I will first introduce Solar Wind Charge eXchange, then discuss the DXL mission and results from flights #1 and #2. =========================================================================
