“Complete the LHC Phase 1 Upgrades….” is how the first project-specific and concrete recommendation (Recommendation 10) of the 2014 Report of the Particle Physics Project Prioritization Panel (P5), “Building for Discovery,” starts. This short phrase has been the mission statement for U.S. CMS scientists from Fermilab and around 30 U.S. institutes for the last six years. On May 1, with the successful outcome of the Department of Energy Critical Decision 4 review, the project has been completed.

Cosmic rays are with us all the time, but they are a pain. This article outlines some of the techniques that are used at Fermilab to remove cosmic rays from experimental data.

Determining the response of the CMS detector to hadrons.

Note: The audio quality of this episode is bad: there are a lot of “dropped frames”.

Dark matter search with bubble chambers

Categories: Cosmic Frontier
Published on: July 17, 2016

This is an electronic image of a typical microscopic quartz particulate found during the investigation of the active mass of the PICO-2L detector after its first run. The image was taken using an EDS-SEM (scanning electron microscopy with X-ray microanalysis). Such particulate contamination was thought to be the cause for the anomalous background, and a profound effort went into its elimination (and suppression of its production) for the follow up PICO-2L WIMP-search run.

Presented here is a description of the PICO experiment, which has achieved one of the world’s best exclusions for the detection of Weakly-Interacting Massive Particles (WIMPs): the leading candidate for the Dark Matter particle.

This podcast is a little longer than usual: 8 minutes, 45 seconds.
