Test Beam Studies Of Silicon Timing for Use in Calorimetry

7 The high luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN is ex8 pected to provide instantaneous luminosities of 5×10 cm−2 s−1. The high luminosities 9 expected at the HL-LHC will be accompanied by a factor of 5 to 10 more pileup compared 10 with LHC conditions in 2015, further increasing the challenge for particle identification 11 and event reconstruction. Precision timing a...

Gravitational Calorimetry

I generalize the quasilocal formulation of thermodynamics of Brown and York to include dilaton theories of gravity as well as Abelian and Yang-Mills gauge matter fields with possible dilaton couplings. The resulting formulation is applicable to a large class of theories including two-dimensional toy models and the low energy limit of string theory as well as to many types of matter such as mass...

High-speed optical sampling using a silicon-chip temporal magnifier.

We demonstrate a single-shot technique for optical sampling based on temporal magnification using a silicon-chip time lens. We demonstrate the largest reported temporal magnification factor yet achieved (>500) and apply this technique to perform 1.3 TS/s single-shot sampling of ultrafast waveforms and to 80-Gb/s performance monitoring. This scheme offers the potential of developing a device tha...
