The third of our largest Xspress 3 systems to date is in final tests at Daresbury Laboratory this week. These Xspress 3 systems with 32 channels each (four 8 channel units interconnected) have timing jitter between units of approx. 12 ns, keeping the whole detector readout in sync. There is no limit on the maximum number of […]

Medipix3 readout systems have until now only been available to members of the consortium. This has given these organisations the advantage of having access to this fast, colour, photon counting ASIC well before other facilities. Quantum Detectors have this week formally agreed a license with CERN for Merlin, a readout system designed by Diamond Light Source […]

/ By QD

Graham Dennis at the Diamond Light Source has used data they have on the Quantum Detectors V2F along with data from Ricardo Hino’s (ESRF) data on the V2F100 to compile a comparison of the uncertainty of measurement against the integration time used in an experiment. The two devices have similar performance down to 0.3 seconds, […]

Often the first experiment we perform with scientists who are using Xspress 3 for the first time is to reproduce the FWHM curve from the datasheet. However at both the LNLS and ANKA, the scientists involved also went on to test the system against their existing readouts performing standard experiments as shown below. Cu Foil […]
