An improved measurement of electron-ion recombination in high-pressure xenon gas

Serra, L.; Sorel, M.; Alvarez, V.; Borges, F. I. G.; Camargo, M.; Carcel, S.; Cebrian, S.; Cervera, A.; Conde, C. A. N.; Dafni, T.; Diaz, J.; Esteve Bosch, Raul; Marí Romero, Antonio Francisco; Mora Mas, Francisco José; Pérez Aparicio, José Luis; Querol Galve, Marcos; Toledo Alarcón, José Francisco; Webb, Rachel; Yahlali Haddou, Nadia (IOP Publishing, 2015-03)

We report on results obtained with the NEXT-DEMO prototype of the NEXT-100 high-pressure xenon gas time projection chamber (TPC), exposed to an alpha decay calibration source. Compared to our previous measurements with ...
Development and Performance Evaluation of High Resolution TOF-PET Detectors Suitable for Novel PET Scanners

Lamprou, Efthymios (Universitat Politècnica de València, 2021-03-04)

[ES] La Tomografía por Emisión de Positrones (PET) es una de las técnicas más importantes en la medicina de diagnóstico actual y la más representativa en el campo de la Imagen Molecular. Esta modalidad de imagen es capaz ...
Fast Timing in Medical Imaging

Lecoq, P.; González Martínez, Antonio Javier; Auffray, E.; Konstantinou, G.; Nuyts, J.; Prior, J. O.; Turtos, R. M.; Varela, J. (Institute of Electrical and Electronics Engineers, 2023-05)

[EN] We report in this article on the Fast Timing in Medical Imaging workshop, (Valencia, 2 June 2022). The workshop gathered 104 attendees from all over the world, with representatives from the academic and industrial ...
Metascintillators: New Results for TOF-PET Applications

Lecoq, Paul; Konstantinou, Georgios; Latella, Riccardo; Moliner Martínez, Laura; Nuyts, Johan; Zhang, Lei; Barrio, John; Benlloch Baviera, Jose María; González Martínez, Antonio Javier (Institute of Electrical and Electronics Engineers, 2022-05)

[EN] We report on the progress on a first generation of realistic size metascintillators for time-of-flight PET. These heterostructures combine dense LYSO or BGO plates, interleaved with fast scintillator layers producing ...
Mitigation of backgrounds from cosmogenic Xe-137 in xenon gas experiments using He-3 neutron capture

Rogers, L.; Jones, B. J. P.; Laing, A.; Pingulkar, S.; Smithers, B.; Woodruff, K.; Adams, C.; Álvarez-Puerta, Vicente; Arazi, L.; Arnquist, I. J.; Azevedo, C. D. R.; Bailey, K.; Ballester Merelo, Francisco José; Benlloch-Rodríguez, J. M.; Borges, F. I. G. M.; Esteve Bosch, Raul; Herrero Bosch, Vicente; Mora Mas, Francisco José; Rodriguez-Samaniego, Javier; Toledo Alarcón, José Francisco (IOP Publishing, 2020-07)

[EN] Xe-136 is used as the target medium for many experiments searching for 0 nu beta beta. Despite underground operation, cosmic muons that reach the laboratory can produce spallation neutrons causing activation of detector ...
Performance study of a wide area SiPM array, ASICs controlled

González Martínez, Antonio Javier; Majewski, Stanislaw; Barbera, J.; Conde Castellanos, Pablo Eloy; Correcher, C.; Hernández Hernández, Liczandro; Morera, C.; Vidal San Sebastián, Luis Fernando; Sánchez Martínez, Filomeno; Stolin, A.; Benlloch Baviera, Jose María (Institute of Electrical and Electronics Engineers (IEEE), 2015-02)

In this paper, the capabilities of a wide-area gamma ray photosensor based on a SiPM array are investigated. For this purpose, we have mounted an array of 144 SiPMs with individual active area of mm and a pitch of mm, thus ...
PMT calibration of a scintillation detector using primary scintillation

Freitas, E. D. C.; Fernandes, L. M. P.; Yahlali, N.; Perez, J.; Alvarez, V.; Borges, F. I. G.; Camargo, M.; Carcel, S.; Cebrian, S.; Esteve Bosch, Raul; Marí Romero, Antonio Francisco; Mora Mas, Francisco José; Pérez Aparicio, José Luis; Rodríguez Samaniego, Javier; Toledo Alarcón, José Francisco (IOP Publishing, 2015-02)

We have studied the calibration of PMTs in scintillation detectors, inducing single electron response on the PMT from primary scintillation produced by x-ray interaction. The results agree with those obtained by the commonly ...
Semi-Monolithic Meta-Scintillator Simulation Proof-of-Concept, Combining Accurate DOI and TOF

Konstantinou, Georgios; Zhang, Lei; Bonifacio, Daniel; Latella, Riccardo; Benlloch Baviera, Jose María; González Martínez, Antonio Javier; Lecoq, Paul (Institute of Electrical and Electronics Engineers, 2024-05)

[EN] In this study, we propose and examine a unique semimonolithic metascintillator (SMMS) detector design, where slow scintillators (BGO or LYSO) are split into thin slabs and read by an array of SiPM, offering ...
