Silicon vertex detector upgrade in the ALPHA experiment / Amole, C (York U., Canada) ; Andresen, G.B (Aarhus U.) ; Ashkezari, M.D (Simon Fraser U.) ; Baquero-Ruiz, M (UC, Berkeley) ; Bertsche, W (Manchester U ; Cockcroft Inst. Accel. Sci. Tech.) ; Burrows, C (Swansea U.) ; Butler, E (CERN) ; Capra, A (York U., Canada) ; Cesar, C.L (Rio de Janeiro Federal U.) ; Chapman, S (UC, Berkeley) et al.
The Silicon Vertex Detector (SVD) is the main diagnostic tool in the ALPHA-experiment. It provides precise spatial and timing information of antiproton (antihydrogen) annihilation events (vertices), and most importantly, the SVD is capable of directly identifying and analysing single annihilation events, thereby forming the basis of ALPHA ' s analysis.

Antihydrogen annihilation reconstruction with the ALPHA silicon detector / Andresen, G B (Aarhus U.) ; Ashkezari, M D (Simon Fraser U.) ; Bertsche, W (Swansea U.) ; Bowe, P D (Aarhus U.) ; Butler, E (CERN) ; Cesar, C L (Rio de Janeiro Federal U.) ; Chapman, S (UC, Berkeley) ; Charlton, M (Swansea U.) ; Deller, A (Swansea U.) ; Eriksson, S (Swansea U.) et al.
The ALPHA experiment has succeeded in trapping antihydrogen, a major milestone on the road to spectroscopic comparisons of antihydrogen with hydrogen. An annihilation vertex detector, which determines the time and position of antiproton annihilations, has been central to this achievement. [...]

4.
Antiproton compression and radial measurements / Alpha Collaboration
Control of the radial profile of trapped antiproton clouds is critical to trapping antihydrogen. We report detailed measurements of the radial manipulation of antiproton clouds, including areal density compressions by factors as large as ten, achieved by manipulating spatially overlapped electron plasmas. [...]

First Attempts at Antihydrogen Trapping in ALPHA / Andresen, G B (Aarhus U.) ; Bertsche, W (Swansea U.) ; Bowe, P D (Aarhus U.) ; Bray, C C (UC, Berkeley) ; Butler, E (Swansea U.) ; Cesar, C L (Rio de Janeiro Federal U.) ; Chapman, S (UC, Berkeley) ; Charlton, M (Swansea U.) ; Fajans, J (UC, Berkeley) ; Funakoshi, R (Tokyo U.) et al.
We discuss aspects of antihydrogen studies, that relate to particle physics ideas and techniques, within the context of the ALPHA experiment at CERN's Antiproton Decelerator facility. We review the fundamental physics motivations for antihydrogen studies, and their potential physics reach. [...]

Evaporative cooling of antiprotons and efforts to trap antihydrogen / Andresen, Gorm Bruun
Evaporative cooling has proven to be an invaluable technique in atomic physics, allowing for the study of effects such as Bose-Einstein condensation [...]

Trapped antihydrogen / ALPHA Collaboration
Precision spectroscopic comparison of hydrogen and antihydrogen holds the promise of a sensitive test of the Charge-Parity-Time theorem and matter-antimatter equivalence. The clearest path towards realising this goal is to hold a sample of antihydrogen in an atomic trap for interrogation by electromagnetic radiation. [...]

Progress towards microwave spectroscopy of trapped antihydrogen / ALPHA Collaboration
Precision comparisons of hyperfine intervals in atomic hydrogen and antihydrogen are expected to yield experimental tests of the CPT theorem. The CERN-based ALPHA collaboration has initiated a program of study focused on microwave spectroscopy of trapped ground-state antihydrogen atoms. [...]
