Evaluation of a method for time-of-flight, wavelength and distance calibration for neutron scattering instruments by means of a mini-chopper and standard neutron monitors
L. Vergara, M. Arai, R. Woracek +9
Accurate conversion of neutron time-of-flight (TOF) to wavelength, and its uncertainty, is of fundamental importance to neutron scattering measurements. Especially in cases where i…
Time- and energy-resolved effects in the boron-10 based Multi-Grid and helium-3 based thermal neutron detectors
A. Backis, A. Khaplanov, R. Al Jebali +33
The boron-10 based Multi-Grid detector is being developed as an alternative to helium-3 based neutron detectors. At the European Spallation Source, the detector will be used for ti…
Tomographic Reconstruction of Two-Dimensional Residual Strain Fields from Bragg-Edge Neutron Imaging
Alexander Gregg, Johannes Hendriks, Christopher Wensrich +7
Bragg-edge strain imaging from energy-resolved neutron transmission measurements poses an interesting tomography problem. The solution to this problem will allow the reconstruction…
Cost Optimisation of an Instrument Suite at an Accelerator-Driven Spallation Source
P. M. Bentley, C. S. Zendler, O. Kirstein
This artcile presents an optimisation of performance and cost of neutron scattering instrumentation at the European Spallation Source. This is done by trading detailed cost functio…
Hardware Aspects, Modularity and Integration of an Event Mode Data Acquisition and Instrument Control for the European Spallation Source (ESS)
Thomas Gahl, Mark Hagen, Richard Hall-Wilton +7
The European Spallation Source (ESS) in Lund, Sweden is just entering the construction phase with 3 neutron instruments having started in its design concept phase in 2014. As a col…
Overcoming High Energy Backgrounds at Pulsed Spallation Sources
Nataliia Cherkashyna, Richard J. Hall-Wilton, Douglas D. DiJulio +18
Instrument backgrounds at neutron scattering facilities directly affect the quality and the efficiency of the scientific measurements that users perform. Part of the background at…
Neutron Position Sensitive Detectors for the ESS
Oliver Kirstein, Richard Hall-Wilton, Irina Stefanescu +17
The European Spallation Source (ESS) in Lund, Sweden will become the world's leading neutron source for the study of materials. The instruments are being selected from conceptual p…
Multi-Grid Boron-10 detector for large area applications in neutron scattering science
Ken Andersen, Thierry Bigault, Jens Birch +12
The present supply of 3He can no longer meet the detector demands of the upcoming ESS facility and continued detector upgrades at current neutron sources. Therefore viable alternat…
TeV Gamma-ray Observations of the Crab and Mkn 501 during Moonshine and Twilight
D. Kranich, R. Mirzoyan, D. Petry +1
TeV Gamma-ray signals from the Crab Nebula and Mkn 501 were detected with the HEGRA CT1 imaging Cerenkov telescope during periods when the moon was shining and during twilight. Thi…
The Cosmic Ray Proton Spectrum determined with the Imaging Atmospheric Cherenkov-Technique
F. Aharonian
The HEGRA system of 4 Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to determine the flux and the spectrum of cosmic ray protons over a limited energy range around…
The time structure of Cherenkov images generated by TeV gamma-rays and by cosmic rays
HEGRA Collaboration, M. Hess et al
The time profiles of Cherenkov images of cosmic-ray showers and of gamma-ray showers are investigated, using data gathered with the HEGRA system of imaging atmospheric Cherenkov te…
Detection of VHE Gamma-rays from Mkn 421 with the HEGRA Cherenkov Telescopes
D. Petry, S. M. Bradbury, A. Konopelko +1
A detection of Gamma-rays from Mkn 421 at energies above 1 TeV is reported, based on observations made in December 1994 - May 1995 with the first two HEGRA Cherenkov telescopes. >F…
