Timelapse of the ALPHA-g addition to the ALPHA Experiment
In 2018 the ALPHA Experiment was expanded with the addition of ALPHA-g. To deliver antiparticles to both ALPHA-g and ALPHA 2 (Spectroscopy trap) a beamline to transport both antiprotons and positrons was also installed. The timelapse videos below show the massive changes, from installation of the beamline, to the addition of new equipment platforms (in

Canadian Members of ALPHA win NSERC John C. Polanyi Award
Members of the ALPHA Collaboration from Canada were recently awarded the NSERC John C. Polanyi Award for their contributions to ALPHA’s sucesses in trapping and measuring antihydrogen atoms. The award honours an individual or team whose Canadian-based research has led to a recent outstanding advance in the natural sciences or engineering. The Canadian group contributes

ALPHA 2 arrives at CERN
Right now everyone at ALPHA is busy assembly the ALPHA 2 apparatus, the sucessor to ALPHA. The most recent parts to arrive have been the atom-trap cryostat built in TRIUMF in Vancouver, and the new superconducting solenoid, built by Oxford Instruments in the UK and financed by the Danish Carlsberg Foundation. They join the catching

First Antiprotons caught in ALPHA 2
The first antiprotons were caught last night in the new ALPHA 2 catching trap, the first component of the next generation of the ALPHA experiment to be installed. This is the representation of the first 'hot dump' — where we release the captured antiprotons, allowing them to annihilate on the surrounding apparatus. The annihilation converts

New ALPHA Octupole being wound at BNL
Our new octupole is being made at Brookhaven National Laboratory – here’s a video that they’ve sent us of the work in progress. The superconducting wire is laid down by a machine-controlled head, and bonded in place as it goes. The new octupole will be welded into the ALPHA 2 cryostat and commissioned at CERN

Carlsberg supports ALPHA
The Carlsberg Foundation of Denmark has awarded a large research grant to ALPHA Spokesperson Professor Jeffrey Hangst of Aarhus University. The award, of 3.3 million Danish kroner, will be used to purchase a new superconducting solenoid magnet for our next generation antihydrogen trapping device, known as ALPHA-2. In 2012, the ALPHA 2 machine will replace

APS Prize awarded to ALPHA Members
The American Physical Society Division of Plasma Physics awarded its John Dawson award for excellence in plasma physics research to several ALPHA members. Will Bertsche, Paul Bowe, Mike Charlton, Joel Fajans, Makoto Fujiwara, Jeffrey Hangst, Niels Madsen, Francis Robicheaux, Daniel Silveira, Dirk Van der Werf and Jonathan Wurtele were cited “For the introduction and use

Beam!
The first beam of the 2011 season was delivered to ALPHA from the AD (Antiproton Decelerator) on the night of May 9th. The image here shows some of the first antiprotons captured in the trap. It's produced by dumping the particles onto an MCP/phosphor – the bright circular shape is the electron plasma used to
