Query: Latest R\&D news and beam test performance of the highly granular
  SiW-ECAL technological prototype for the ILC   High precision physics at future colliders as the International Linear
Collider (ILC) require unprecedented high precision in the determination of the
energy of final state particles. The needed precision will be achieved thanks
to the Particle Flow algorithms (PF) which require highly granular and hermetic
calorimeters systems.The physical proof of concept of the PF was performed in
the previous campaign of beam tests of physic prototypes within the CALICE
collaboration. One of these prototypes was the physics prototype of the
Silicon-Tungsten Electromagnetic Calorimeter (SiW-ECAL) for the ILC. In this
document we present the latest news on R\&D of the next generation prototype,
the technological prototype with fully embedded very front-end (VFE)
electronics, of the SiW-ECAL. Special emphasis is given to the presentation and
discussion of the first results from the beam test done at DESY in June 2017.
The physics program for such beam test consisted in the calibration and
commissioning of the current set of available SiW ECAL modules; the test of
performance of individual slabs under 1T magnetic fields; and the study of
electromagnetic showers events.
