CAST: Recent results & future outlook
Papaevangelou, Thomas H.; Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Yıldız, Süleyman Cenk; Borghi, Silvia; Brauninger, Heinrich W.; Cantatore, G.; Çetin, Serkant Ali; Ezer, Cemile; Yıldız, Süleyman Cenk (Verlag Deutsches Elektronen-Synchrotron, 2010-07)The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipes of an LHC dipole. The analysis of data taken so far has shown no signal above the ... -
CAST: Status and latest results
Dafni, Theopisti; Aune, Stephan; Barth, Kurt L.; Borghi, Silvia; Brauninger, Heinrich W.; Cantatore, G.; Carmona, J. M.; Çetin, Serkant Ali (Hamburg Verlag, 2011)In July 2011 CAST finished the data-taking of its nominal programme having scanned axion masses up to ∼ 1.18 eV/c2. Here we present the first results of the data taken in 2008 first year of the last data-taking campaign ... -
Latest results and prospects of the CERN Axion Solar Telescope
Irastorza, G.; Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Borghi, Silvia; Brauninger, Heinrich W.; Çetin, Serkant Ali (IOP Publishing, 2011)The CERN Axion Solar Telescope (CAST) experiment searches for axions from the Sun converted into few keV photons via the inverse Primakoff effect in the high magnetic field of a superconducting Large Hadron Collider (LHC) ... -
A new micromegas line for the CAST experiment
Andriamonje, Samuel; Aune, Stephan; Braeuninger, Heinrich; Dafni, Theopisti; Doğan, Berkol; Fanourakis, George (Elsevier, 2007-10-21)A low background Micromegas detector has been operating on the Cern Axion Solar Telescope (CAST) experiment at CERN for the search of solar axions during the first phase of the experiment. The detector operated efficiently ... -
The new micromegas X-ray detectors in CAST
Tomas, Antonio; Aune, Stephan; Dafni, Theopisti; Fanourakis, George K.; Ferrer-Ribas, Esther; Yıldız, Süleyman Cenk (John Wiley&Sons, 2011-07)The last generation of micromegas, called microbulk, are ahead of classical gas detectors (or even other kind of micro-pattern gas detectors) in gain stability, efficiency (by operation at high pressure), simplicity, ... -
Performance of micromegas detectors in the CAST Experiment
Yıldız, Şükrü C.; Aune, Stephan; Dafni, Theopisti; Davenport, M.; Fanourakis, George K.; Ferrer-Ribas, Esther (IOP Publishing, 2012)CERN Axion Solar Telescope (CAST) experiment is searching for axions coming from the Sun. Inside transverse magnetic fields, axions can be converted into X-rays, which can be detected by X-ray detectors. The expected energy ... -
Probing the eV-mass range for solar axions with CAST
Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Brauninger, Heinrich W.; Cantatore, G.; Carmona, J. M.; Çetin, Serkant Ali; Yıldız, Süleyman Cenk; CAST Collaboration (IEEE, 2010)The CERN Axion Solar Telescope (CAST) is searching for solar axions which could be produced in the core of the Sun via the so-called Primakoff effect. Not only would these hypothetical particles solve the strong CP problem, ... -
Rare event searches based on micromegas detectors: The T-REX project
Dafni, Theopisti; Aune, Stephan; Fanourakis, George K.; Ferrer-Ribas, Esther; Galan, J.; Garcia, J.A.; Yıldız, Süleyman Cenk (IOP Publishing, 2012)Micromegas readouts are an attractive option for many of the rare event searches, due to their performance regarding energy resolution, gain stability, homogeneity and material budget. The T-REX project aims at developing ... -

Status and perspectives of the CAST experiment
Lakic, Biljana; Arık, Metin; Aune, Stephan; Barth, Kurt L.; Belov, Alexander S.; Borghi, Silvia (IOP Publishing, 2012)The CERN Axion Solar Telescope (CAST) is currently the most sensitive axion helioscope designed to search for axions produced by the Primakoff process in the solar core. CAST is using a Large Hadron Collider (LHC) test ... -
The T-REX projec t: Micromegas for rare event searches
Dafni, Theopisti; Aune, Stephan; Fanourakis, George K.; Ferrer-Ribas, Esther; Yıldız, Şükrü C. (IOP Publishing, 2012)The T-REX project aims at developing novel readout techniques for Time Projection Chambers for experiments searching for Rare Events. The Micromegas detectors are a good option, because of their good performance regarding ... -
X-ray detection with Micromegas with background levels below 10-6keV-1cm-2s-1
Aune, Stephan; Aznar, Francisco; Calvet, David; Dafni, Theopisti; Diago, A.; Druillole, Frederic; Yıldız, Süleyman Cenk (IOP Publishing, 2013-12)Micromegas detectors are an optimum technological choice for the detection of low energy x-rays. The low background techniques applied to these detectors yielded remarkable background reductions over the years, being the ...
