Single-electron beam observed in IOTA for the first time

From left: Aleksandr Romanov, Giulio Stancari, Vladimir Shiltsev and Chip Edstrom, seen here in the Electrical Service Building, where some of the IOTA apparatuses and control reside, stand by screens that display IOTA activity. The photo was taken on Oct. 31, 10:15 p.m., when three electrons were circulating in the machine. Romanov points to the computer screen on the left, where a camera image of the beam was visible. The screen on the right shows one of the first plots of the discrete steps. Photo: Giulio Stancari

One of the most interesting scientific topics at IOTA will be studies of beams made of a single electron.

Superconducting film technology leads to record performance for low-frequency SRF cavity

An SRF team at Fermilab has demonstrated record performance from an accelerating cavity using a technique that could lead to significant cost savings for future accelerators.

MicroBooNE demonstrates use of convolutional neural networks on liquid-argon TPC data for first time

Recently, the MicroBooNE experiment published a paper describing how they used convolutional neural networks — a particular type of deep neural network — to sort individual pixels coming from images made by a particular type of detector.

Beautiful Higgs decays

A Fermilab accelerator team has designed a device that chops accelerator-generated ion beams under highly demanding conditions.

Extracting signals of elusive particles from giant chambers filled with liquefied argon

A Brookhaven team working on the MicroBooNE neutrino experiment use software to develop images that trace neutrinos’ interactions in a bath of minus 303-degree Fahrenheit liquid argon.

Breaking the symmetry between fundamental forces

Measuring a certain parameter of particles emerging from Tevatron collisions helps us better understand how the unified electromagnetic and weak forces broke into separate distinct entities in the universe’s early moments.

The secret to measuring the energy of an antineutrino

Fermilab’s MINERvA experiment gives a boost to the particle physics field by sharpening a model of a frequent, pesky phenomenon.

MicroBooNE measures charged-particle multiplicity in first neutrino-beam-based result

This plot shows the observed multiplicity of charged particles emerging from the neutrino interaction point in MicroBooNE data (points with error bars) and three models (histograms). Data favors lower multiplicity compared to all the models.

The path to extracting deeper science from neutrinos starts with understanding the details of their interactions — the manner in which they scatter from protons and neutrons and the effects of the argon nuclear volume on this scattering.

Neutrino experiment at Fermilab delivers an unprecedented measurement

MiniBooNE scientists discover a way to eliminate a major source of uncertainty in subatomic measurements with muon neutrinos.
