Simulation of STIRAP from the 1S to the 2S states of the Hydrogen/Antihydrogen atoms

AbdAlGhaffar K. Amer, A. Capra, T. Friesen +4

Achieving a high population of antihydrogen/hydrogen atoms in the 2S level is essential for spectroscopy measurements testing similarities between matter and antimatter. We propose…

Electron Cyclotron Resonance (ECR) Magnetometry with a Plasma Reservoir

E. D. Hunter, A. Christensen, J. Fajans +3

The local magnetic field in a Penning-Malmberg trap is found by measuring the temperatures that result when electron plasmas are illuminated by microwaves pulses. Multiple heating…

Status and Prospects for CPT Tests with the ALPHA Experiment

T. Friesen

A primary goal of the ALPHA experiment at CERN is to perform precise tests of CPT symmetry. Here, we report on the significant progress made in recent years on antihydrogen spectro…

In situ electromagnetic field diagnostics with an electron plasma in a Penning-Malmberg trap

C. Amole, M. D. Ashkezari, M. Baquero-Ruiz +37

We demonstrate a novel detection method for the cyclotron resonance frequency of an electron plasma in a Penning-Malmberg trap. With this technique, the electron plasma is used as…
