Publication Precise timing with the picosec-micromegas detector(Soc Italiana Fisica, 2020-01-01) Sampsonidis, D.; Bortfeldt, J.; Brunbauer, F.; David, C.; Desforge, D.; Fanourakis, G.; Franchi, J.; Gallinaro, M.; Garcia, F.; Giomataris, I; Gustavsson, T.; Guyot, C.; Iguaz, F. J.; Kebbiri, M.; Kordas, K.; Lampoudis, C.; Legou, P.; Liu, J.; Lupberger, M.; Maillard, O.; Maniatis, V; Manthos, I; Muller, H.; Oliveri, E.; Papaevangelou, T.; Paraschou, K.; Pomorski, M.; Resnati, F.; Ropelewski, L.; Schneider, T.; Schwemling, P.; Scorsone, E.; Sohl, L.; Van Stenis, M.; Thuiner, P.; Tsipolitis, Y.; Tzamarias, S. E.; Wang, X.; White, S.; Zhang, Z.; Zhou, Y.; Veenhof, R.; Bursa Uludağ Üniversitesi/Fen Edebiyat Fakültesi/Fizik Bölümü.; GJK-8031-2022This work presents the concept of the PICOSEC-Micromegas detector to achieve a time resolution below 30 ps. PICOSEC consists of a two-stage Micromegas detector coupled to a Cherenkov radiator and equipped with a photo-cathode. The results from single-channel prototypes as well as the understanding of the detector in terms of detailed simulations and preliminary results from a multichannel prototype are presented.Publication Progress on the PICOSEC-micromegas detector development: Towards a precise timing, radiation hard, large-scale particle detector with segmented readout(Elsevier, 2020-04-01) Kordas, K.; Bortfeldt, J.; Brunbauer, F.; David, C.; Desforge, D.; Fanourakis, G.; Franchi, J.; Gallinaro, M.; Garcia, F.; Giomataris, I.; Gonzalez-Diaz, D.; Gustavsson, T.; Guyot, C.; Iguaz, F. J.; Kebbiri, M.; Legou, P.; Liu, J.; Lupberger, M.; Maillard, O.; Maniatis, I.; Manthos, I.; Mueller, H.; Niaouris, V.; Oliveri, E.; Papaevangelou, T.; Paraschou, K.; Pomorski, M.; Qi, B.; Resnati, F.; Ropelewski, L.; Sampsonidis, D.; Schneider, T.; Schwemling, P.; Sohl, L.; van Stenis, M.; Thuiner, P.; Tsipolitis, Y.; Tzamarias, S. E.; Veenhof, R.; Wang, X.; White, S.; Zhang, Z.; Zhou, Y.; Veenhof, Rob; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Fizik Bölümü.; GJK-8031-2022This contribution describes the PICOSEC-Micromegas detector which achieves a time resolution below 25 ps. In this device the passage of a charged particle produces Cherenkov photons in a radiator, which then generate electrons in a photocathode and these photoelectrons enter a two-stage Micromegas with a reduced drift region and a typical anode region. The results from single-channel prototypes (demonstrating a time resolution of 24 ps for minimum ionizing particles, and 76 ps for single photoelectrons), the understanding of the detector in terms of detailed simulations and a phenomenological model, the issues of robustness and how they are tackled, and preliminary results from a multi-channel prototype are presented (demonstrating that a timing resolution similar to that of the single-channel device is feasible for all points across the area covered by a multi-channel device).
