The LHCb detector at the LHC

A. A. Alves, +889 more
TL;DR: The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva).
Journal ArticleDOI

Metal and hybrid TimePix detectors imaging beams of particles

TL;DR: In this article, the uniformity of response of the pixel matrix with respect to ion mass, energy and detection position has been studied for imaging low energy ion beams and as candidates for building an electronic focal plane of a laser mass-spectrometer.
Journal ArticleDOI

Metal micro-detector TimePix imaging synchrotron radiation beams at the ESRF Bio-Medical Beamline ID17

TL;DR: The results obtained for high intensity synchrotron radiation minibeams illustrate an excellent performance of the TimePix providing in real time 2D image of the dose distribution over many beams in a 14×14 mm 2 area.
Journal ArticleDOI

“Stealth Scripts”: Ultrashort Pulse Laser Luminescent Microscale Encoding of Bulk Diamonds via Ultrafast Multi-Scale Atomistic Structural Transformations

TL;DR: In this paper , the authors enlighten nonlinear wavelength-, polarization-, intensity-, pulsewidth-, and focusing-dependent photoexcitation and energy deposition mechanisms in diamonds, coupled with the propagation of ultrashort laser pulses and ultrafast off-focus energy transport by electron-hole plasma, transient plasma- and hot-phononinduced stress generation and the resulting variety of diverse structural atomistic modifications in the diamond lattice.
Journal ArticleDOI

Shaping and monitoring of the mini-beam structures for the spatially fractionated hadron radiation therapy

TL;DR: In this paper, the design of collimators and their effectiveness for the purposes of the fractionated mini-beam radiation therapy were evaluated by Monte Carlo simulations by measuring charged particles intensity distribution in multi-beam structures shaped by slit or matrix collimator exploring low energy proton beam at the Tandem generator.
