Spectroscopy of nuclei far from stability and astrophysics studies are of major interests in a number of nuclear physics laboratories. In view of limiting beam intensities and the low energy multi-particle emission, (examples: n+12C = 3a (Ref 1), 14N(paaa) Ref 2 or 20Mg(βpα) Ref 3), the instrumentation calls for gas detection medium with a 4p solid angular cover and precise tracking...

32. Status and Future Developments of Micro-pattern Gas Detectors for low-energy nuclear physics applications at FRIB

Dr Marco Cortesi (Facility for Rare Isotope Beams)

Rare isotope (RI) beam facilities are now important tools for nuclear physics. The Facility for Rare Isotope Beams (FRIB), located on the campus of the Michigan State University, is a new world-leading user facility for the study of RIs using the in-flight fragmentation method. The unprecedented potential discovery of a modern rare isotope beam facility, such as FRIB, can only be realized by...

33. TMM: A Triple Micro-Mesh gaseous structure with ultra-low ion backflow for gaseous photon detectors sensitive to visible light

Kunyu Liang (University of Science and Technology of China (CN))

Gas photomultiplier tubes (gas-PMT) for visible light detection using micro-pattern gas detectors have been widely studied owing to their potential advantages, such as large detection area with low cost, high spatial and time resolutions, and resistance to magnetic field. But photocathodes sensitive to visible light exhibit a significant aging effect when subjected to excessive ions...

34. A large area 100 channel PICOSEC Micromegas detector with sub 20 ps time resolution

Antonija Utrobicic (Rudjer Boskovic Institute (HR))

The PICOSEC Micromegas precise timing detector is based on a Cherenkov radiator coupled to a semi-transparent photocathode and a Micromegas amplification structure. The first proof of concept single-channel small area prototype was able to achieve time resolution below 25 ps. One of the crucial aspects in the development of the precise timing gaseous detectors applicable in high-energy physics...

35. Towards robust PICOSEC Micromegas precise timing detectors

Ms Marta Lisowska (European Organization for Nuclear Research (CERN))

13/12/2022, 12:50

The PICOSEC Micromegas detector is a precise timing gaseous detector based on a Cherenkov radiator coupled to a semi-transparent photocathode and a Micromegas amplifying structure. First single-pad prototypes, equipped with a non-resistive Micromegas and a Cesium Iodide (CsI) photocathode, demonstrated a time resolution below 𝜎 = 25 ps. However, to make the concept appropriate to physics...
