“…For the evaluation of the light output and PSD performance, double time-of-flight measurements were made at the nELBE facility in Dresden, Germany [38,49,50]. The neutron beamline at the ELBE Center for High Power Radiation Sources produces a pulsed beam, with each pulse consisting a prompt flash of Bremsstrahlung radiation followed by a neutron spectrum ranging from tens of keV up to approximately 20 MeV.…”

“…The nELBE facility mimics the pulsed structure and multi-particle nature of a proton therapy treatment scenario, but with lower mean and maximum neutron energies (by a factor of approximately 5), reduced repetition rates (by 1-3 orders of magnitude, depending on the ELBE repetition rate), and integral count rates (by a factor of approximately 2, based on PHITS simulations of a typical proton therapy treatment) when compared to the clinical proton therapy facility at OncoRay [38,50,51]. However, this situation is ideal for characterization of OGS in a more controlled environment than can be produced in a clinical proton therapy facility.…”

For accurate and simultaneous imaging of fast neutrons (FNs) and prompt gamma rays (PGs) produced during proton therapy, the selection of a highly performant detector material is crucial. In this work, a promising candidate material known as organic glass scintillator (OGS) is characterized for this task. To this end, a precisely-timed source of neutrons and Bremsstrahlung radiation produced by the nELBE facility was used to study the light output and neutron/gamma ray pulse shape discrimination (PSD) properties of a 1 × 1 × 20 cm3 OGS bar with double-sided readout. Furthermore, the energy, timing, and depth-of-interaction (DOI) resolutions of 1 × 1 × 10 cm3 and 1 × 1 × 20 cm3 OGS and EJ-200 bars were characterized with radioactive sources. For electron-equivalent energies above 0.5 MeVee, OGS was found to have excellent PSD capabilities (figure-of-merit above 1.27), energy resolution (below 12%), coincident time resolution (below 500 ps), and DOI resolution (below 10 mm). This work establishes the data analysis methods required for hybrid FN/PG imaging using OGS, and demonstrates the materials' excellent performance for this application.

“…Research into relativistic plasmas was initiated at HZDR in the mid-2000s. Laser systems were installed for synergy reasons as additions to the existing accelerator-driven photon and particle source called ELBE [46] , sharing structural shielding and building infrastructure, as well as the radiation monitoring and interlock system of ELBE. Further control systems are complete additions due to the higher flexibility of a laser-plasma experimental arrangement compared to a fixed accelerator machine.…”

The next generation of high-power lasers enables repetition of experiments at orders of magnitude higher frequency than what was possible using the prior generation. Facilities requiring human intervention between laser repetitions need to adapt in order to keep pace with the new laser technology. A distributed networked control system can enable laboratory-wide automation and feedback control loops. These higher-repetition-rate experiments will create enormous quantities of data. A consistent approach to managing data can increase data accessibility, reduce repetitive data-software development and mitigate poorly organized metadata. An opportunity arises to share knowledge of improvements to control and data infrastructure currently being undertaken. We compare platforms and approaches to state-of-the-art control systems and data management at high-power laser facilities, and we illustrate these topics with case studies from our community.
