ICARUS-Q: Integrated control and readout unit for scalable quantum processors / Park, Kun Hee (Singapore Natl. U.) ; Yap, Yung Szen (Singapore Natl. U.) ; Tan, Yuanzheng Paul (Singapore Natl. U.) ; Hufnagel, Christoph (Singapore Natl. U.) ; Nguyen, Long Hoang (Nanyang Technol. U.) ; Lau, Karn Hwa (Unlisted, SG) ; Bore, Patrick (Singapore Natl. U.) ; Efthymiou, Stavros (Technol. Innovation Inst., UAE) ; Carrazza, Stefano (Technol. Innovation Inst., UAE ; Milan U. ; INFN, Milan ; CERN) ; Budoyo, Rangga P. (Singapore Natl. U.) et al.
We present a control and measurement setup for superconducting qubits based on Xilinx 16-channel radio-frequency system-on-chip (RFSoC) device. The proposed setup consists of four parts: multiple RFSoC boards, a setup to synchronise every digital to analog converter (DAC), and analog to digital converter (ADC) channel across multiple boards, a low-noise direct current (DC) supply for tuning the qubit frequency and cloud access for remotely performing experiments. [...]

A pulsed high-voltage decelerator system to deliver low-energy antiprotons / Husson, A (IJCLab, Orsay) ; Kim, B H (Seoul Natl. U., Dept. Phys. Astron.) ; Welker, A (CERN) ; Charlton, M (Swansea U.) ; Choi, J J (Seoul Natl. U., Dept. Phys. Astron.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crépin, P -P (Paris, Lab. Kastler Brossel) ; Crivelli, P (Zurich, ETH-CSCS/SCSC) et al.
The GBAR (Gravitational Behavior of Antihydrogen at Rest) experiment at CERN requires efficient deceleration of 100 keV antiprotons provided by the new ELENA synchrotron ring to synthesize antihydrogen. This is accomplished using electrostatic deceleration optics and a drift tube that is designed to switch from -99 kV to ground when the antiproton bunch is inside – essentially a charged particle “elevator” – producing a 1 keV pulse. [...]

Accumulation of Positrons from a LINAC Based Source / GBAR Collaboration
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H. It will use H + ions formed by the interaction of antiprotons with a dense positronium cloud, which will require about $10^{10}$ positrons to produce one H + [...]

Development of a PbWO$_4$ Detector for Single-Shot Positron Annihilation Lifetime Spectroscopy at the GBAR Experiment / Kim, B H (Seoul Natl. U.) ; Choi, J J (Seoul Natl. U.) ; Chung, M (UNIST, Ulsan) ; Cladé, P (Paris, Lab. Kastler Brossel) ; Comini, P (IRFU, Saclay) ; Crivelli, P (Zurich, ETH) ; Crépin, P-P (Paris, Lab. Kastler Brossel) ; Dalkarov, O (Lebedev Inst.) ; Debu, P (IRFU, Saclay) ; Dodd, L (Swansea U.) et al.
We have developed a PbWO$_{4}$ (PWO) detector with a large dynamic range to measure the intensity of a positron beam and the absolute density of the ortho-positronium ($\mathrm{o-Ps}$) cloud it creates. A simulation study shows that a setup based on such detectors may be used to determine the angular distribution of the emission and reflection of $\mathrm{o-Ps}$ to reduce part of the uncertainties of the measurement.

Positron production using a 9 MeV electron linac for the GBAR experiment / Charlton, M. (Swansea U.) ; Choi, J.J. (Seoul Natl. U., Dept. Phys. Astron.) ; Chung, M. (UNIST, Ulsan) ; Cladé, P. (Paris, Lab. Kastler Brossel) ; Comini, P. (IRFU, Saclay) ; Crépin, P.P. (Paris, Lab. Kastler Brossel) ; Crivelli, P. (Zurich, ETH) ; Dalkarov, O. (Lebedev Inst.) ; Debu, P. (IRFU, Saclay) ; Dodd, L. (Swansea U.) et al.
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. [...]

Study of the interactions of pions in the CALICE silicon-tungsten calorimeter prototype / CALICE Collaboration
A prototype silicon-tungsten electromagnetic calorimeter for an ILC detector was tested in 2007 at the CERN SPS test beam. Data were collected with electron and hadron beams in the energy range 8 to 80 GeV. [...]

Construction and Commissioning of the CALICE Analog Hadron Calorimeter Prototype / CALICE Collaboration
An analog hadron calorimeter (AHCAL) prototype of 5.3 nuclear interaction lengths thickness has been constructed by members of the CALICE Collaboration. The AHCAL prototype consists of a 38-layer sandwich structure of steel plates and highly-segmented scintillator tiles that are read out by wavelength-shifting fibers coupled to SiPMs. [...]
