Pulsed Production of Antihydrogen in AEgIS
/ AEgIS Collaboration
Cold antihydrogen atoms are a powerful tool to probe the validity of fundamental physics laws, and it's clear that colder atoms, generally speaking, allow an increased level of precision.
After the first production of cold antihydrogen ($\bar{H}$) in 2002, experimental efforts have progressed continuously (trapping, beam formation, spectroscopy), with competitive results already achieved by adapting to cold antiatoms techniques previously well developed for ordinary atoms. Unfortunately, the number of $\bar{H}$ atoms that can be produced in dedicated experiments is many orders of magnitude smaller than available hydrogen atoms, which are at hand in large amount, so the development of novel techniques that allow the production of $\bar{H}$ with well defined conditions (and possibly control its formation time and energy levels) is essential to improve the sensitivity of the methods applied by the different experiments.
We present here the first experimental results concerning the production of $\bar{H}$ in a pulsed mode where the time when 90\% of
the atoms are produced is known with an uncertainty of around 250~ns. [...]

Cold atoms in space: community workshop summary and proposed road-map
/ Alonso, Iván (Balearic Islands U.) ; Alpigiani, Cristiano (Washington U., Seattle) ; Altschul, Brett (South Carolina U.) ; Araújo, Henrique (Imperial Coll., London) ; Arduini, Gianluigi (CERN) ; Arlt, Jan (Aarhus U.) ; Badurina, Leonardo (King's Coll. London) ; Balaž, Antun (Belgrade, Inst. Phys.) ; Bandarupally, Satvika (Florence U. ; INFN, Florence) ; Barish, Barry C. (LIGO Lab., Caltech) et al.
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. [...]

The validity of the Weak Equivalence Principle (WEP) as predicted by General Relativity has been tested up to astounding precision using ordinary matter. The lack hitherto of a stable source of a probe being at the same time electrically neutral, cold and stable enough to be measured has prevented highaccuracy testing of the WEP on anti-matter. [...]

Forming a pulsed beam of cold antihydrogen using charge-exchange with Rydberg positronium (Ps) is the goal of the AEḡIS collaboration, which aims to a first gravity measurement on neutral antimatter. Recently achieved results in Ps formation and laser spectroscopy in the main AEḡIS apparatus are summarized. [...]
