Three high altitude drop tests of a 33.5 m Ringsail Canopy were conducted in the Fall of 2004 from Ft. Sumner, New Mexico. The deployment conditions were consistent with those expected on Mars when using this parachute in conjunction with the Viking 16.1 m supersonic parachute as part of a two-stage system. A 0.34 million cubic meter helium balloon was used to hoist the test article to 36 km altitude. When the instrumented test article was released, a drogue parachute was static-line deployed. The main deployment was triggered 21 seconds later at Mach 0.54 and 148 Pa. This test series was the first in a program of three test series designed to develop this new parachute system for Mars exploration. This paper describes one method by which an Earth qualification test program for a Mars parachute can be conducted.
One of the goals of the PXIE program at Fermilab [1] is to demonstrate the capability to form an arbitrary bunch pattern from an initially CW 162.5 MHz H-bunch train coming out of an RFQ. The bunch-by-bunch selection will take place in the 2.1 MeV Medium Energy Beam Transport (MEBT) [2] by directing the undesired bunches onto an absorber that needs to withstand a beam power of up to 21 kW, focused onto a spot with a ~2 mm rms radius. A prototype of the absorber was manufactured from molybdenum alloy TZM, and tested with an electron beam up to the peak surface power density required for PXIE, 17W/mm 2 . Temperatures and flow parameters were measured and compared to analysis. This paper describes the absorber prototype and key testing results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
