A novel concept for ion blocking in gas-avalanche detectors was developed, comprising
cascaded micro-hole electron multipliers with patterned electrodes for ion defocusing. This …

We summarize the development of visible-sensitive gaseous photomultipliers, combining a
semitransparent bi-alkali photocathode with a state-of-the-art cascaded electron multiplier …

The extraction efficiency f for the photoelectrons emitted from a CsI photocathode into
gaseous Xe–CH 4 and Ne–CH 4 mixtures is investigated by Monte Carlo simulation. The …

Operation results are presented of a UV-sensitive gaseous photomultiplier (GPM) coupled
through a MgF 2 window to a liquid-xenon scintillator. It consisted of a reflective CsI …

Monte Carlo simulation is used to investigate the fluctuations in the Xe proportional

Experimental measurements of the extraction efficiency f of the UV-induced photoelectrons
emitted from a CsI photocathode into gas mixtures of Ne with CH 4, CF 4, CO 2 and N 2 are …

The knowledge of the electron transverse diffusion in detection media is mandatory to
assess the accuracy in systems that require precise event tracking. A new experimental …

In this work, a new device developed to measure the transverse diffusion of electrons in
gases is described. In this device, electrons are generated in a semitransparent cesium …
