The meson target stations and the high power spallation

The Paul Scherrer Institut operates two meson graphite targets, Target M and Target E, for creating the world's most intense pion and muon beams by using 590 MeV protons and c.w. beam currents of up to 2.4 mA (=1.4 MW). The energy deposit on Target E is 20 kW mA−1. The proton beam feeds also the spallation neutron source SINQ, which operates in DC mode and produces thermal and cold

In situ observation of graphene sublimation and multi

The sublimation of few-layer graphene, such as a 10-layer stack, is particularly interesting compared with the sublimation of monolayer graphene. In few-layer graphene, different layers often spontaneously fuse together, forming nanostructures in situ, on top of 1

NASA asked university students around the country to help solve the pesky problem of lunar dust as the agency plans for sustainable human exploration of the Moon. Through the 2021 competitive Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge and the Space Grant project, NASA has awarded nearly $1 million to seven university teams to develop their innovative lunar dust

Graphite Sublimation Tests for Target Development for the

Graphite sublimation tests have been conducted in a high-temperature oven, which is operated either in high vacuum or in an 1-atm cover gas of helium (or argon). Preliminary data of the sublimation rate of graphite foils at ~2400 K in vacuum are consistent with theoretical prediction. Additional tests of graphite rods (15 mm in diameter and 300 mm long) have been conducted in high vacuum and

Journal of Instrumentation, Volume 15, November 2020

The Muon g−2 experiment at Fermilab (E989) aims to measure the anomalous magnetic moment, a μ, of the muon with a precision of 140 parts-per-billion. This requires a precise measurement of both the anomalous spin precession frequency, ω a, of muons stored in a magnetic field of 1.45 T, and a precise measurement of that magnetic field in terms of the shielded proton Larmor frequency, ω' p .
