EISCAT_3D Skibotn – July 2019 update

The EISCAT_3D site itself will only occupy 120x120 meters but extensive works need to be done to secure the area from land-slide risks. For that work, we need to build a temporary construction road to be used to transport material from higher grounds down. We needed also to clear a larger area from trees. The temporary construction road will later be removed and the unused land will be returned to nature.  ...

Also in EISCAT_3D – Preparing for first article tests

Preparing for first article tests The first article of the Antenna Unit (AU) will arrive at the Production Engineering and Test (PET) test site, located at EISCAT in Kiruna, in July. After installation by the vendor, ECRIEE, the initial AU tests will verify dimensions, cabling, electrical installations and the environmental control system (cooling, heat, etc). For the RF tests, the AU will be equipped with Solid State Power Amplifiers (SSPA) – from Japan which are controlled by the in-house developed Pulse and Steering Control Unit (PSCU) system. In preparation for those tests, the project staff, here represented by Robert Juhlin and Assar Westman, have setup parts of the transmitter system at our offices for pre-tests. For synchronisation of the individual channels, a white-rabbit system has been deployed.  The control system is GUI based. The PSCU logic and amplifiers used here will not be the ones used in the final system. Both the PSCU and the transmitter system are sourced via external contracts....

HPC System Expert

HPC System Expert

Status at 2019-07-04: The terms and conditions for this position will be changed and the vacancy will be re-advertised in autumn HPC System Expert EISCAT Scientific Association is recruiting an HPC System Expert for EISCAT3D. Job Description EISCAT3D is a major scientific research instrument and infrastructure composed of three large phased-array antennas, a powerful transmitter, and complex computation/processing hardware and software (see e.g. https://www.eiscat.se/about/eiscat3d7/). The implementation phase started 1 September 2017 and the system will be ready for use in 2021. EISCAT3D will have three operating sites and each site will have it's own 10's of TFLOPS compute cluster for signal processing and data analysis. The main focus of this role is to maximise system performance for both the realtime signal processing tasks and batch data analysis tasks. The input data rate for the system is up to 4 Tbps, so experience with I/O limited rather than compute limited systems would be beneficial. Main Duties System development and performance optimization of the E3D clusters for both real...

Status at 2019-07-04: Position filled Applications Developer EISCAT Scientific Association is recruiting an Applications Developer for EISCAT3D. Job Description EISCAT3D is a major scientific research instrument and infrastructure composed of three large phased-array antennas, a powerful transmitter, and complex computation/processing hardware and software (see e.g. https://www.eiscat.se/about/eiscat3d7/). The implementation phase started 1 September 2017 and the system will be ready for use in 2021. This will be a varied role primarily concerned with the development and maintenance of the web interface to EISCAT3D which will be used for all day to day operations by both the users and the system operators. As the EISCAT3D system will be remotely operated this role also covers the development and maintenance of PC or tablet applications to allow remote system maintenance tasks such as powering on and off the system and calibration. EISCAT3D will operate for decades so the role would suit someone familiar with balancing features and dependencies against maintenance costs. EISCAT3D will be operational in 2021 and...

Each EISCAT3D site will have its own 10's of TFLOPS compute cluster for signal processing and data analysis and each cluster node will be GPU accelerated. The focus of this role is to design and implement algorithms for both signal processing and data analysis that will run on the on-site clusters. Initial tasks will include beam forming of the input data and re-implementing existing analysis algorithms for the new hardware. The role will then grow with analysis requirements once the system is operational in 2021. Main Duties Implementation of high performance software for signal processing and data analysis.

Antenna Unit Factory Visit

Antenna Unit Factory Visit

Antenna Unit Factory Visit in China Some of the E3D project team members visited the Antenna Unit manufacturer, East China Research Institute of Electronic Engineering (ECRIEE), last week. The purpose was to inspect the first antenna unit (the First Article) made. This unit will, after further testing and specification validation, be shipped to EISCAT for field testing. ECRIEE is located in Hefei, P. R. of China.   The container will come equipped with climate control and seven empty standard 19” equipment racks. The transmitters, receivers and supplemental equipment (networks, etc) come from other vendors and will be mounted at the sites after the antenna units have been installed by ECRIEE. Also in the photo, our E3D System Integration Engineer, Harri Hellgren.   For easier inspection and further measurements, the antennas and its ground plane were lifted off the support structure and was moved outside. Note: the color of the antenna units will not be white – as shown in the photos, rather industry grey. 109 antenna units plus...

EISCAT_3D Data Management Plan

EISCAT_3D Data Management Plan The EISCAT_3D system represents a significant upgrade to EISCAT’s incoherent scatter radar (ISR) capabilities. The system is designed with a great deal more flexibility than the present EISCAT ISRs can provide, largely through the use of signal digitization very early in the processing chain and the use of a very large number of smaller antennas. Internally, this represents an extremely large amount of data bandwidth, on the order of a few terabytes per second. The data streams from the individual antennas are, however, of little use unless they are combined and this combination can be accomplished at various stages in the system, thus greatly affecting the load on the data processing and communication subsystems. Data management and data processing management are, as a result, important considerations in the system architecture and operation. Read the full report here. ...
