The third-generation instrument era is approaching, and the Einstein Telescope (ET) giant interferometer becoming a reality, with potential to be installed at an underground site where seismic noise about 100 times lower than surface. Moreover, new available technologies experience acquired from operating advanced detectors are key further extending detection bandwidth down 2–3 Hz, possibility of suspending cryogenic payload.

Monolayer graphene was grown via chemical vapor deposition and transferred onto electron microscopy (TEM) grids. A monochromatic gun has been employed to perform the in 30 – 900 eV range ultra-high vacuum. The transparency is obtained from absolute measurement direct beam current transmitted one, by means a Faraday cup. We observed going ∼20 ∼80% for within experimental energy...

M. Derrick D. Krakauer S. Magill B. Musgrave J. Repond and 95 more

Energy flows in deep inelastic electron-proton scattering are investigated at a centre-of-mass energy of 269 GeV for the range Q2 ≥ 10 GeV2 using ZEUS detector. A comparison is made between events with and without large rapidity gap hadronic system proton direction. The flows, corrected detector acceptance resolution, shown these two classes both HERA laboratory frame Breit frame. From differences shapes we conclude that QCD radiation suppressed large-rapidity-gap eents compared to gap.
