Understanding of the new horizontal instability at the PS Booster after LIU / Antuono, Chiara (Sapienza Universita e INFN, Roma I (IT)) ; Zannini, Carlo (CERN) ; Rumolo, Giovanni (CERN) ; Asvesta, Foteini (CERN) ; Migliorati, Mauro (Sapienza Universita e INFN, Roma I (IT))
Following the LHC Injectors Upgrade (LIU) project at CERN, the Proton Synchrotron Booster (PSB) has been upgraded to operate with a new injection kinetic energy of 160 MeV and an extraction energy of 2 GeV. To understand the performance of the accelerator in this new energy range, a series of measurements have been conducted, especially devoted to the beam stability to ensure the optimal operation of the machine.

Performance Improvement Studies of the Fixed Target Beams along the CERN Injector Chain / Prebibaj, Tirsi (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Damerau, Heiko (CERN) ; Fraser, Matthew Alexander (CERN) ; Di Giovanni, Gian Piero (CERN) ; Huschauer, Alexander (CERN) ; Li, Kevin Shing Bruce (CERN) ; Schenk, Michael (CERN) ; Velotti, Francesco Maria (CERN)
Within the LHC Injectors Upgrade (LIU) project, LHC injectors received major upgrades that resulted in an unprecedented beam brightness. In the framework of the Physics Beyond Colliders (PBC) study, the full potential of the upgraded injectors is being explored for the improvement of the Fixed Target (FT) beams as well. [...]

A 60 μW front-end for 10 ps resolution monolithic pixel sensors in a 130nm SiGe BiCMOS process / Picardi, Antonio (CERN ; Geneva U.) ; Cardella, Roberto (Geneva U.) ; Iacobucci, Giuseppe (Geneva U.) ; Kugathasan, Thanushan (Geneva U.) ; Paolozzi, Lorenzo (Geneva U.)
This paper presents the development and optimization of a front-end circuit and the design of a monolithic sensor demonstrator with a high spatial resolution (hexagonal pixels with 50 μ m pitch) and sub-10 picosecond timing capability for the detection of ionizing radiation. The system combines a monolithic sensor in a SiGe BiCMOS process with a front-end architecture based on a SiGe Heterojunction Bipolar Transistor (HBT). [...]

A Fast Timing Layer Concept for a Compton-TOF-PET Module / Cala’, Roberto (CERN ; Milan Bicocca U.) ; Kratochwil, Nicolaus (CERN ; U. Vienna (main)) ; Gundacker, Stefan (RWTH Aachen U.) ; Polesel, Andrea (CERN ; Milan Bicocca U.) ; Paganoni, Marco (Milan Bicocca U.) ; Auffray, Etiennette (CERN) ; Pizzichemi, Marco (CERN)
The possibility to improve depth of interaction (DOI) resolution and coincidence time resolution (CTR) of a pixellated PET module by enabling light re-circulation inside it with a light guide is well known. Typically the light guide consists of a non-scintillating material of about 1 mm thickness. [...]
