Stable and unstable isotopes of the heavy noble gas xenon find use in various medical
applications. However, apart from $^{133}$Xe, used for Single Photon Emission Computed Tomography,
radioactive isotopes of xenon are currently complicated to obtain in small quantities. [...]

/ Chojnacki, M (CERN ; Geneva U.) ; Kulesz, K (CERN ; Geneva U.) ; Michelon, I (CERN ; INFN, Padua) ; Azaryan, N (CERN ; Mickiewicz U., Poznan) ; Barbero, E (CERN) ; Crepieux, B (CERN) ; Lica, R (CERN ; Bucharest, IFIN-HH) ; Murawski, Ł (NCBJ, Swierk) ; Ziemba, M (NCBJ, Swierk) ; Piersa-Siłkowska, M (CERN) et al.
The long-lived xenon isomers $^{{129} \textrm{m}}$Xe and $^{{131} \textrm{m}}$Xe are of interest for the GAMMA-MRI project, which aims at developing a novel imaging modality based on magnetic resonance of polarized unstable tracers. Here, we present the steps leading to and following the production of these two isomers via neutron irradiation of highly-enriched $^{128}$Xe and $^{130}$Xe gas samples at two high-flux reactors, the High-Flux Reactor (Réacteur à haut flux, RHF) at the Institut Laue-Langevin (ILL) and the MARIA reactor at the National Centre for Nuclear Research (NCBJ).

Time resolution and power consumption of a monolithic silicon pixel prototype in SiGe BiCMOS technology
/ Paolozzi, L. (Geneva U.) ; Cardarelli, R. (INFN, Rome2) ; Débieux, S. (Geneva U.) ; Favre, Y. (Geneva U.) ; Ferrère, D. (Geneva U.) ; Gonzalez-Sevilla, S. (Geneva U.) ; Iacobucci, G. (Geneva U.) ; Kaynak, M. (IHP, Frankfurt) ; Martinelli, F. (CERN ; Ecole Polytechnique, Lausanne) ; Nessi, M. (CERN) et al.
SiGe BiCMOS technology can be used to produce ultra-fast, low-power silicon pixel sensors that provide state-of-the-art time resolution even without an internal gain mechanism. The development of such sensors requires the identification of the main factors that may degrade the timing performance and the characterisation of the dependance of the sensor time resolution on the amplifier power consumption. [...]

This paper presents a small-area monolithic pixel detector ASIC designed in 130 nm SiGe BiCMOS technology for the upgrade of the pre-shower detector of the FASER experiment at CERN. The purpose of this prototype is to study the integration of fast front-end electronics inside the sensitive area of the pixels and to identify the configuration that could satisfy at best the specifications of the experiment.

A group of Early-Career Researchers (ECRs) has been given a mandate from the European Committee for Future Accelerators (ECFA) to debate the topics of the current European Strategy Update (ESU) for Particle Physics and to summarise the outcome in a brief document [1]. A full-day debate with 180 delegates was held at CERN, followed by a survey collecting quantitative input. [...]

The proof-of-concept prototype of the Picosecond Avalanche Detector, a multi-PN junction monolithic silicon detector with continuous gain layer deep in the sensor depleted region, was tested with a beam of 180 GeV pions at the CERN SPS. The prototype features low noise and fast SiGe BiCMOS frontend electronics and hexagonal pixels with 100 μm pitch. [...]

Picosecond Avalanche Detector — working principle and gain measurement with a proof-of-concept prototype
/ Paolozzi, L. (Geneva U. ; CERN) ; Munker, M. (Geneva U.) ; Cardella, R. (Geneva U.) ; Milanesio, M. (Geneva U.) ; Gurimskaya, Y. (Geneva U.) ; Martinelli, F. (Geneva U.) ; Picardi, A. (Geneva U. ; CERN) ; Rücker, H. (IHP, Frankfurt) ; Trusch, A. (IHP, Frankfurt) ; Valerio, P. (Geneva U.) et al.
The Picosecond Avalanche Detector is a multi-junction silicon pixel detector based on a $\mathrm{(NP)_{drift}(NP)_{gain}}$ structure, devised to enable charged-particle tracking with high spatial resolution and picosecond time-stamp capability. It uses a continuous junction deep inside the sensor volume to amplify the primary charge produced by ionizing radiation in a thin absorption layer. [...]
