Rare isotope (RI) beams facilities are now critical tools for nuclear physics. The Facility for Rare Isotope Beams (FRIB), located on the campus of Michigan State University, is a world-class 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 implementing state-of-the-art experimental equipment capable of studying these isotopes at a high beam rate and high performance.
Originally developed for high-energy physics (HEP), implementation of Micro-pattern Gas Detector (MPGD) technology as gas avalanche readouts has expanded to other fields, including nuclear physics, astrophysics, neutrino physics, material science, neutron detection, and medical imaging. MPGDs offer great flexibility and allow geometry and performance to be tailored to specific working conditions and requirements. The requirements of a typical low-energy nuclear physics experiment (LENP) with RI beam are generally very different from HEP fixed-target experiments, so that substantial efforts and resources are necessary to develop MPGD architectures optimized for LENP environments.
In this work, we describe our latest results and progress obtained with novel gas avalanche concepts designed to target applications at the Facility for Rare Isotope Beam (FRIB). In particular, we will describe recent progress in the development of Multi-layer Thick Gas Electron Multiplier (M-THGEM) structures as readouts for the tracking detector system of the focal-plane of the FRIB S800 spectrometer. I will also report on the implementation of the RD51 Scalable Readout System (SRS) as a data acquisition system (DAQ) for the tracking detectors, which required the development of an external synchronization process to integrate the SRS into the FRIBDAQ framework.
Finally, we will discuss the latest advances in the development of a low-pressure, heavy-ion 2D imaging system based on the novel Multi-Mesh THGEM (MM-THGEM) readout for fission and fission-like reactions study. We will described operational principle and performance in terms of time (< 1 ns σ) and spatial resolution (< 1 mm σ), ion-feedback suppression, and stability. Perspective and future plans will be also described.
