First ICCUB Numerical Relativity Waveform Catalog of Eccentric Black Hole Binaries

We release the first Numerical Relativity catalog of Institut de Ciencies del Cosmos at University of Barcelona (ICCUB) consisting of 128 simulations for black hole binaries. All simulations in this first release correspond to highly eccentric binaries with eccentricity $e = (0.62,0.79)$ which develop zoom-whirls up to three close passages before merger. We consider aligned, equal spin configurations in the range $\chi = (-0.5, 0.5)$ and equal mass ratios. For each simulation, we provide the modes $(\ell, m)$ of Weyl scalar $\psi_4^{(\ell,m)}$ extrapolated to $r = \infty$, with $\ell \leq 4$. In addition, we provide the corresponding strain modes obtained by computing a double time integral of the Weyl scalar modes. Moreover, we provide metadata and the parameter files required to reproduce our results using the open-source code Einstein Toolkit. A Python code that facilitates the access to the data is available on Git-Hub.

CLIC Background Studies and optimization of the innermost tracker elements

The harsh machine background at the Compact Linear Collider (CLIC) forms a strong constraint on the design of the innermost part of the tracker. For the CLIC Conceptual Design Report, the detector concepts developed for the International Linear Collider (ILC) were adapted to the CLIC environment. We present the new layout for the Vertex Detector and the Forward Tracking Disks of the CLIC detector concepts, as well as the background levels in these detectors. We also study the dependence of the background rates on technology parameters like thickness of the active layer and detection threshold.

Geiger-Mode Avalanche Photodiodes in Particle Detection

It is well known that avalanche photodiodes operated in the Geiger mode above the breakdown voltage offer a virtually infinite sensitivity and time accuracy in the picosecond range that can be used for single photon detection. However, their performance in particle detection remains still unexplored. In this contribution, we are going to expose the different steps that we have taken in order to prove the efficiency of Geiger mode avalanche photodiodes in the aforementioned field. In particular, we will present an array of pixels of 1mmx1mm fabricated with a standard CMOS technology for characterization in a test beam.
