Research Article on WIMPS and other Dark Matter

Research Article

1) It is set up as any other scientific experiment data would be: an abstract, an introduction, then the method, then the data/results, then any conclusions that were drawn.
2) The abstract is sort of a preview of what the experiment covers, providing background information of the subject and a very general overview.
3) Data collected included amounts of WIMPS detected in the underground contraption that detects them, the DRIFT-I detector. The DRIFT-I is a vacuum that is specifically designed to detect neutrinos and other WIMPS, with customized settings for different particles, even detecting the direction from which the neutrinos are coming using electron avalanches to amplify the movement of them.
4) These amounts of "events" (times neutrinos were detected) averaged out to a very scattered "less than one event per kg of target" per day. The conclusion? The DRIFT-I detector was a success at directional sensitivity, their original goal.
5) At first, the scientists thought that it would be possible to construct such a machine to detect even the direction of a neutrino, so they calculated various factors such as the earth/sun rotation and their relation to neutrino motion, and then discovered a method to amplify that movement. This led to a hypothesis- then the implementation of the ideas into the machine. Tests were made, data was collected, and the experiment was proven a success.

REFLECTION: This pertains to the class because it's talking about dark matter and the sensitivity of some devices meant to detect what is thought to be dark matter, like neutrinos. The article was kind of hard to understand because of all the lingo, but looking some stuff up and trying to extrapolate helped a little. XD
