“…That means that to a large extent bursts with two or more electrons were excluded. For triggering and selecting in the analysis stage a plastic scintillator and Lead-Glass (PbGl) calorimeter were placed downstream and included into the data acquisition via a DRS4 chip-based readout system [16]. Signals from these devices were used to identify and reject spills with other than one electron incident on the RICH.…”

Cerenkov technology is often the optimal choice for particle identification in high energy particle collision applications. Typically, the most challenging regime is at high pseudorapidity (forward) where particle identification must perform well at high high laboratory momenta. For the upcoming Electron Ion Collider (EIC), the physics goals require hadron ($\pi$, K, p) identification up to $\sim$~50 GeV/c. In this region Cerenkov Ring-Imaging is the most viable solution.\newline The speed of light in a radiator medium is inversely proportional to the refractive index. Hence, for PID reaching out to high momenta a small index of refraction is required. Unfortunately, the lowest indices of refraction also result in the lowest light yield ($\frac{dN_\gamma}{dx} \propto \sin^2{\left(\theta_C \right)}$) driving up the radiator length and thereby the overall detector cost. In this paper we report on a successful test of a compact RICH detector (1 meter radiator) capable of delivering in excess of 10 photoelectrons per ring with a low index radiator gas ($CF_4$). The detector concept is a natural extension of the PHENIX HBD detector achieved by adding focusing capability at low wavelength and adequate gain for high efficiency detection of single-electron induced avalanches. Our results indicate that this technology is indeed a viable choice in the forward direction of the EIC. The setup and results are described within.Comment: 10 pages, 15 figure

“…We rejected most of the background e − that either arrived in the particle beam or were produced by μ − decays by removing events with small energy depositions. The waveforms [43][44][45][46][47] of the signals from the scintillation counters were recorded using some data acquisition electronics developed by us. A prototype was used earlier in an experiment to determine the limits on the annihilation cross sections σ A of antiprotons of kinetic energy E ≈ 125 keV in thin target foils [46,48,49].…”

“…Complete details are presented in Ref. [42]. In this manner, excellent time resolution (provided by the 1 GSPS sampling and nanosecond time stamping also between different detectors) was achieved at 10-bit resolution over the 3.5 µs duration of the stored event.…”

He NE-213 Scintillation Gamma-rays Fast neutrons Pulse-shape discrimination a b s t r a c t A first comparison has been made between the pulse-shape discrimination characteristics of a novel 4 He-based pressurized scintillation detector and a NE-213 liquid-scintillator reference detector using an Am/Be mixed-field neutron and gamma-ray source and a high-resolution scintillation-pulse digitizer. In particular, the capabilities of the two fast neutron detectors to discriminate between neutrons and gamma-rays were investigated. The NE-213 liquid-scintillator reference cell produced a wide range of scintillation-light yields in response to the gamma-ray field of the source. In stark contrast, due to the size and pressure of the 4 He gas volume, the 4 He-based detector registered a maximum scintillationlight yield of 750 keV ee to the same gamma-ray field. Pulse-shape discrimination for particles with scintillation-light yields of more than 750 keV ee was excellent in the case of the 4 He-based detector. Above 750 keV ee its signal was unambiguously neutron, enabling particle identification based entirely upon the amount of scintillation light produced.
