Juno is a neutrino detector under construction 750m below Jiangmen in China. A collaboration between 17 countries, 730 scientists from 74 universities and national laboratories have worked on it. At its heart will be a 34.5m diameter acrylic sphere filled with 20,000 tons of liquid scintillator, which will emit photons if neutrinos interact with it – neutrinos sourced from eight ...

SmallSat 2024: Hyperspectral imager
At the Small Satellite Conference in Utah, Imec announced a hyperspectral sensor with an on-chip line-based filter covering 450 – 900nm in 96 bands. It had equidistantly divided spectral bands and, compared with its previous generation, double the TDI (time-delayed-integration) capacity – to 10 line per band. Underneath the filter is a ‘2/3inch’ 2,048pixel image sensor from AMS – the ...
Long thin pixels boost spectrometer sensor sensitivity
Hamamatsu Photonics has launched a pair of linear CMOS image sensors with long thin pixels to increase sensitivity in spectrometers, without hampering resolution. “The elongated vertical pixel enables efficient light collection, even with shorter integration times,” according to the company. “Surpassing conventional CMOS in the VUV [vacuum ultra-violet, see graph] region, both sensors exhibit remarkable sensitivity from 140 to 1,000nm.” ...
Eight channels of data acquisition at 10Gsample/s
Spectrum Instrumentation has introduced a way to parallel its 12bit 10Gsample/s data acquisition cards up to eight channels, that can also produce 16 12bit channels at 5Gsample/s. Called Star-Hub, it works with the company’s recently introduced M5i.33xx series of PCIe digitisers. “The Star-Hub option is installed by mounting a single piggyback module onto any of the M5i series cards in ...
Lasers measure wind velocity at long distance to improve mathematical models
Danish company Vind-Vind is developing a turbulence model for the effect of wind on structures in complex environments. It will eventually include the atmosphere high above the volume of interest with wind gusts from different directions. As such, said Vind-Vind CEO Per Jørgensen, wind-tunnel measurements are not good enough and he needed real-world measurements throughout a large volume of atmosphere ...
Spectrum adds GPU-based digital down-conversion to digitiser fleet
Spectrum Instrumentation has added a GPU-based digital down-conversion (DDC) option to its PC-based ‘SCAPP’ software, used with its PCIe signal digitiser cards – effectively ADCs for PCs. Working with sufficiently-powerful Cuda-based GPUs, the DDC option allows on-the-fly baseband signal extraction, and is offered as an alternative to FPGA-based DDC and its associated programming. “The GPU, which can have thousands of ...
Holographic grating spectrometer for sub-nm resolution across 810 to 965nm
Thorlabs has announced a holographic grating spectrometer that spans 810 to 965 nm with sub-nanometre resolution. HG10 is fibre-based acquires at up to 130,000 scan/s, enabled by the USB 3.0 interface. External synchronisation is via a TTL-level trigger input. Inside, the spectrometer is based on the company’s Ganymede series of optical coherence tomography imagers. “The development of the HG10 was ...
12bit dual-channel PCIe card samples at 2x 3.2Gsample/s
German digitiser company Spectrum has introduced a dual-channel sampler board – an ADC board – that takes 12bit samples on both channels simultaneously at 3.2Gsample/s. Called M5i.3321-x16, it has 1GHz bandwidth front-end amplifiers with programmable full-scale ranges from ±200mV to ±2.5V, plus variable offset. Other models in the M5i family offer 2GHz bandwidth. The full input capacity can be streamed continuously ...
Spectrum adds support for Nvidia Clara AGX
Spectrum Instrumentation has added driver support for the Nvidia Clara AGX computing architecture for AI medical instruments. This means that Spectrum’s digitiser boards (ADCs), arbitrary waveform generators (AWGs) and digital IO cards can be used with Clara AGX (right) for electronic signal acquisition and the generation of analogue and digital signals. “The Nvidia Clara AGX developer kit provides a platform ...
Rack mount spectrum monitors reach 43.5GHz
Anritsu has created the MS27201A remote spectrum monitor series, that includes a 43.5GHz version for new satellite downlink bands. A 110MHz measurement bandwidth supports common satellite downlink spans, DANL (displayed average noise level) is -164dBm and the typical TOI (third-order intercept point) is +20dBm. Other MS27201A versions work up to 9GHz or 20GHz. All work down to 9kHz. “Combining RF performance ...
