“…The insertion depth refers to the height of the optical fiber embedded into the scintillator. The scintillating photons produced by irradiation will propagate through the optical fiber to the other end only if their incidence angle with respect to the optical fiber axis is less than the acceptance angle 𝜃, which is given as: [38]…”

An active filter stack spectrometer based on the scintillator and optical fiber is proposed and characterized for measuring the ultrashort X-ray spectrum. The active filter stack spectrometer consists of multiple detection modules, each of which has three components: a scintillator, an optical fiber, and a PMT. After simulation optimization of the detection module for better coupling efficiency, a detection module was fabricated and assembled for subsequent coupling efficiency measurements. Two proof-of-principle experiments using an X-ray source were conducted to validate the feasibility of this active filter stack spectrometer.

With the development of laser technologies, nuclear reactions can happen in high-temperature plasma environments induced by lasers and have attracted a lot of attention from different physical disciplines. However, studies on nuclear reactions in plasma are still limited by detecting technologies. This is mainly due to the fact that extremely high electromagnetic pulses (EMPs) can also be induced when high-intensity lasers hit targets to induce plasma, and then cause dysfunction of many types of traditional detectors. Therefore, new particle detecting technologies are highly needed. In this paper, we report a recently developed gated fiber detector which can be used in harsh EMP environments. In this prototype detector, scintillating photons are coupled by fiber and then transferred to a gated photomultiplier tube which is located far away from the EMP source and shielded well. With those measures, the EMPs can be avoided which may result that the device has the capability to identify a single event of nuclear reaction products generated in laser-induced plasma from noise EMP backgrounds. This new type of detector can be widely used as a time-of-flight (TOF) detector in high-intensity laser nuclear physics experiments for detecting neutrons, photons, and other charged particles.
