The VMM3a is an Application Specific Integrated Circuit (ASIC), specifically developed for the readout of gaseous detectors. Originally within ATLAS New Small Wheel (NSW) upgrade, it has been successfully integrated into Scalable Readout System (SRS) RD51 collaboration. This allows, to use also in small laboratory set-ups and mid-scale experiments, which make Micro-Pattern Gaseous Detectors (MPGDs). As part integration SRS, data transfer scheme was optimised reach a high rate-capability...
The European Spallation Source (ESS) will provide long neutron pulses for experiments on a suite of different instruments. Most these perform data acquisition in event mode, i.e. each detected be characterised by one absolute timestamp and pixel identifier pair. Slow controls metadata from EPICS, such as sample environment measurements motor positions, also timestamped at their source, so that all are streamed list events instead histograms. A flexible aggregation streaming system is being...
Abstract The RD51 collaboration developed the Scalable Readout System (SRS) as part of its R&D activities on Micro-Pattern Gaseous Detectors. This common multi-purpose readout system allows to read out small detectors (0.2k channels) up mid-sized experiments with multiple (2.5k 5k channels). To cope increased demands detectors, electronics and speed, a new front-end ASIC—the VMM3a—was integrated into SRS. led development scalable, self-triggered high-rate that provides energy, space time...
The response of a position-sensitive Li-glass scintillator detector being developed for thermal-neutron detection with 6 mm position resolution has been investigated using collimated beams thermal neutrons. was moved perpendicularly through the neutron in 0.5 to 1.0 horizontal and vertical steps. Scintillation detected an 8 × pixel multi-anode photomultiplier tube on event-by-event basis. In general, several pixels registered large signals at each neutron-beam location. number registering...
Abstract The Multi-Blade (MB) Boron-10-based neutron detector is the chosen technology for three instruments at European Spallation Source (ESS): two ESS reflectometers, ESTIA and FREIA, Test Beam Line. A fourth MB has been built, installed commissioned user operation of reflectometer Amor PSI (Switzerland). can be considered a downscaled version ESTIA. They are based on same Selene guide concept, optimized performing focusing reflectometry small samples. experience gained invaluable future...
User Datagram Protocol (UDP) is a commonly used protocol for data transmission in small embedded systems. UDP as such unreliable and packet losses can occur. The achievable rates suffer if optimal sizes are not used. alternative, Transmission Control (TCP) guarantees the ordered delivery of automatically adjusts to match capability link. Nevertheless often favored over TCP due its simplicity, memory instruction footprints. Both implemented all larger operating systems commercial frameworks....
