A Study of Heavy Higgs Properties at a Multi-TeV e+e- Collider

The precise determination of the masses of the neutral and charged heavy Higgs bosons is a crucial input for the study of Supersymmetry and its relation with cosmology through dark matter. This paper presents a study of e+e- -> HA and H+H- production at sqrts=3 TeV. The analysis is performed with full simulation and reconstruction accounting for beamstrahlung effects and the overlay of gamma gamma -> hadrons events. Results are presented in terms of the accuracy on the determination of the masses and widths of the heavy Higgs bosons in two benchmark scenarios.

Characterisation of a Pixel Sensor in 0.20 micron SOI Technology for Charged Particle Tracking

This paper presents the results of the characterisation of a pixel sensor manufactured in OKI 0.2 micron SOI technology integrated on a high-resistivity substrate, and featuring several pixel cell layouts for charge collection optimisation. The sensor is tested with short IR laser pulses, X-rays and 200 GeV pions. We report results on charge collection, particle detection efficiency and single point resolution.

A Rad-hard CMOS Active Pixel Sensor for Electron Microscopy

Monolithic CMOS pixel sensors offer unprecedented opportunities for fast nano-imaging through direct electron detection in transmission electron microscopy. We present the design and a full characterisation of a CMOS pixel test structure able to withstand doses in excess of 1 MRad. Data collected with electron beams at various energies of interest in electron microscopy are compared to predictions of simulation and to 1.5 GeV electron data to disentagle the effect of multiple scattering. The point spread function measured with 300 keV electrons is (8.1 +/- 1.6) micron for 10 micron pixel and (10.9 +/- 2.3) micron for 20 micron pixels, respectively, which agrees well with the values of 8.4 micron and 10.5 micron predicted by our simulation.
