The physics programme and the design are described of a new collider for particle nuclear physics, Large Hadron Electron Collider (LHeC), in which newly built electron beam 60 GeV, up to possibly 140 energy collides with intense hadron beams LHC. Compared HERA, kinematic range covered is extended by factor twenty negative four-momentum squared, $Q^2$, inverse Bjorken $x$, while luminosity $10^{33}$ cm$^{-2}$s$^{-1}$ LHeC projected exceed integrated HERA two orders magnitude. devoted an...

Beam Delivery Simulation (BDSIM) is a program that simulates the passage of particles in particle accelerator. It uses suite standard high energy physics codes (Geant4, ROOT and CLHEP) to create computational model accelerator combines accurate tracking routines with all processes Geant4. This unique combination permits radiation detector background simulations accelerators where both required over long range or many revolutions circular machine, as well interaction material
The TOTEM experiment at the LHC has performed first measurement $\sqrt{s} = 13$ TeV of $ρ$ parameter, real to imaginary ratio nuclear elastic scattering amplitude $t=0$, obtaining following results: $ρ= 0.09 \pm 0.01$ and 0.10 0.01$, depending on different physics assumptions mathematical modelling. unprecedented precision measurement, combined with total cross-section measurements in an energy range larger than 10 (from 2.76 13 TeV), implied exclusion all models classified published by...
The High Luminosity Large Hadron Collider (HL–LHC) will require unprecedented orbit stability at the low-beta experiments, ATLAS and CMS. Because effect of seismic noise might become a relevant source luminosity loss, several studies have been conducted to characterise actual ground motion in LHC tunnel. In preparation for official groundbreaking civil engineering work high upgrade, that started on 15 June 2018 parallel beam operation, sensors were installed permanently monitor close these...
Beam collimation in high-energy colliders is customarily carried out by means of massive amorphous absorbers surrounding the circulating beam. Several studies were performed last decades to establish an innovative technique that relies on particle deflection channeling between crystalline planes a bent crystal. We report operational use crystal Large Hadron Collider was achieved during special high-${\ensuremath{\beta}}^{\ensuremath{\ast}}$ physics run with low-intensity beams, representing...
A hollow electron beam has been proposed as an active control tool to remove the halo from high-energy, high-current hadron or ion machines (such High-Luminosity Large Hadron Collider). To study removal rate and assess effect on core, one of two lenses in Relativistic Heavy Ion Collider was changed a Gaussian profile profile. We describe design verification parameters well methods minimize distortions, which can result emittance increase. The alignment with by using backscattered detector...
Simulations of final-focus performance for high-energy linear colliders, including realistic imperfections, demonstrating that an improved traditional modular system is much more robust than a compact system.

Accurate ultra-broadband measurements were obtained for the purpose of modeling two unique W-band flipchip Schottky diodes. Single-anode (SA) and zero bias detector (ZBD) Schottkys, available from Virginia Diodes Inc., characterized DC to 125GHz using on-wafer coplanar waveguide (CPW) test fixtures on a 10-mil Quartz substrate.

Interferometry is a high resolution technique that enables us to study physical processes at the smallest spatial scales we can probe with our telescopes. In infrared and in (sub-)millimetric Very-Long-Baseline Interferometry, restricted sparse arrays only few telescopes or antennas. While imaging would most intuitive way interpret interferometric data, recovering images from an ill-posed" problem Fourier inversion techniques are restricted. this work, explore novel scheme based on...
