In the CERN CMS experiment, CSC detectors are employed and operated with a gas mixture based on CF4. Since 2016, two Single Wire Proportional Chambers (SWPCs) have been installed along the gas line to monitor the quality of the gas. The first SWPC was positioned immediately after the gas mixer unit, while the second was placed within the gas loop. SWPCs exhibit a high sensitivity to the...
The expected limitations on the use of HFCs and other fluorinated gases motivated the opening of a new line of R&D in RPCs: sealed RPCs. This approach requires only very low amounts of gas and dispenses with the very complex and expensive recirculation and/or recycling gas systems.
At the moment it is not clear if this solution can cover all the fields of application of RPCs, but it seems...
At low energy frontier among the Standard Model testing methods and searches for new physics beyond it are precision spectrum shape and correlation coefficient measurements in nuclear and neutron beta decay. For identification and 3D-tracking of low-energy electrons a special type of gas-based detector was designed that minimizes scattering and energy loss. In the first approach the gas...
The ongoing work on the development and testing of a prototype of a Micromegas (MM) detector and its front end electronics will be presented. Presently a revision of the front-end electronics with a new discharge protection circuit is being tested and results will be discussed. Moreover, a first insight on the development of a new ASIC for the MM readout will be provided.
For the AMBER (NA66)...
The study of nuclear fission is integral to the fundamental understanding of nuclear physics and it has significant implications in many sectors, such as energy generation, space research, and radioisotope synthesis for medical uses. With the VAriable MOde Spectrometer (VAMOS++) facility, at Grand Accélérateur National d'Ions Lourds (GANIL), we are exploring the nature of nuclear fission...
Thanks to a tool specially developed for that, we measured Paschen curves with real resistive Micromegas electrodes, both real mesh and real resistive anode layer. The resistive Micromegas structure and geometry studied correspond to those of the New Small Wheel (NSW) detector upgrade project of the ATLAS experiment at CERN.
Also these Paschen curves have been obtained for different gas...
Resistive Plate Chamber (RPC) detectors in the Compact Muon Solenoid (CMS) experiment operate with a gas mixture comprised of 95.2% of C2H2F4, that provides a high number of ion-electron pairs, 4.5% of iC4H10, that ensures the suppression of photon-feedback effects and 0.3% of SF6, used as an electron quencher to further operate the detector in streamer-free mode. C2H2F4 is known to be a...
The advancement of accelerator technologies helps the High Energy Physics (HEP) community to reach higher collision rates to measure rare physical observables with unprecedented precessions. This imposes a great challenge to the rate handling capabilities of the detectors. In the HEP experiments, gas-filled detectors are commonly used for tracking, triggering, and timing measurements. Gas...
Yttrium oxide thin films are deposited using indigenously developed metal organic precursor (2,2,6,6-tetra methyl-3,5-hepitane dionate) yttrium, commonly known as Y(thd)3 (synthesized by ultrasound method). Microwave electron cyclotron resonance plasma assisted metal organic chemical vapor deposition process was used for these depositions. Depositions were carried out at a substrate...
In the context of climate change, one of the main contributors to global warming is the greenhouse effect. Regulations have been implemented in different areas of society to reduce or ban the use of greenhouse gases, such as freon. Despite the fact that large-scale experiments (such as the ones held at CERN) have been excluded from these restrictions, as a scientific community we have the duty...
