2. [P01] Investigation of nitrogen enriched silicon detectors

Jan Cedric Honig (Albert Ludwigs Universitaet Freiburg (DE))

Poster (short oral)

A promising approach to increase the radiation hardness of existing detector designs are defect engineering and the dedicated and controlled enrichment of the silicon bulk with foreign atoms. NitroStrip is a RD50 project with the goal of understanding the effect of nitrogen enrichment on the radiation hardness of high resistivity float zone silicon.
Previous works suggest an increased...

40. [P02] A Study for Hit-time Reconstruction of Belle II Silicon Vertex Detector

Poster (short oral)

The Belle II experiment, with a vertex detector installed, started operation in the spring of 2019. The experiment aims to probe new physics beyond the Standard Model by analyzing a large number of generated $\mathrm{B}\bar{\mathrm{B}}$-pairs in high-luminosity ${\mathrm{e}}^{+}{\mathrm{e}}^{-}$ collisions at SuperKEKB (KEK, Japan). The Silicon Vertex Detector (SVD) is a part of the vertex detector and is composed...

74. [P03] Particle identification in Belle II silicon vertex detector

Poster (short oral)

Particle identification plays an important role in the physics program of the Belle II experiment at the SuperKEKB asymmetric-energy e+e− collider. We have developed a particle identification (PID) framework based on energy loss information in the silicon-strip vertex detector (SVD) for charged pions, kaons, and protons using D∗0→D0[→K−π+]π+ and Λ→pπ− decay samples. The study is based on...

46. [P04] The CLICTD monolithic CMOS sensor

Katharina Dort (Justus-Liebig-Universitaet Giessen (DE))

Poster (short oral)

CLICTD is a monolithic pixel sensor fabricated in a modified 180 nm CMOS imaging process with a small collection electrode design and a high-resistivity epitaxial layer. It features an innovative sub-pixel segmentation scheme and is optimised for fast charge collection and high spatial resolution. The chip was developed to target the requirements for the tracking detector of the proposed...

54. [P05] Development of the thin and fine-pitch silicon strip detector aiming for the Belle II upgrade

Katsuro Nakamura (KEK)

Poster (short oral)

The Belle II experiment has started to consider a possible upgrade leading a higher luminosity than the current design value. Due to a larger beam background and a higher trigger rate expected at the upgraded luminosity, the Belle II silicon strip detector, which measures the vertex position together with the Belle II pixel detector, has to be upgraded as well. Aiming for this upgrade, we are...
