Since the discovery of the muon, particle physicists have carried out a series of experiments aimed at measuring flavor violation in charged-lepton interactions. To date, no such violation has been observed. The Mu2e experiment at Fermilab will search for the charged-lepton-flavor-violating process of coherent muon-to-electron conversion in the presence of a nucleus with a sensitivity four...

Extending the energy frontier beyond the LHC would be vital to elucidate the nature of electroweak symmetry breaking and whatever new physics that might be found at the LHC. We propose here a proton-proton (pp) collider in a 100 km ring, with center of mass (CM) energy of ~100 TeV which would have substantial discovery potential for new heavy
particles and new physics beyond the Standard...

Laser-plasma accelerators (LPAs) [1] have produced GeV electron beams (e-beams) from cm-scale devices, demonstrating that LPAs have great potential for reducing accelerator size and cost [2]. LPA experiments performed to date utilize a single laser that drives the wakefield for injection and acceleration. For applications such as high-energy accelerators, LPA designs will rely on sequencing...

The Muon Ionisation Cooling Experiment (MICE) will demonstrate ionisation cooling, an essential technology for a
Neutrino Factory and/or Muon Collider, by measuring a 10% reduction in emittance of a muon beam. A realistic
demonstration requires beams closely resembling those expected at the front-end of a Neutrino Factory, i.e. with large
transverse emittance and momentum spreads. The MICE...

Systems of detectors installed at the LHC operate in the radiation field produced by LHC beam collisions. To measure the radiation damage of the components of the detector systems, prototype devices are irradiated at test beam facilities that reproduce the radiation conditions expected at the LHC. The profile of the test beam and the fluence applied per time must then be known. Techniques...

The NOvA experiment has an 810 km long baseline and uses the upgraded NuMI neutrino beam from Fermi National Accelerator Laboratory to study neutrino oscillation parameters. The two fully active, functionally identical detectors are placed 14 milliradians off axis to access a narrow neutrino energy spectrum, due to the pion decay kinematics. The 300 ton near detector, located at Fermilab, is...

The LHCb experiment is a spectrometer dedicated to the study of heavy flavor at the LHC. The rate of proton-proton collisions at the LHC is 15 MHz, of which only 5 kHz can be written to storage for offline analysis. For this reason the LHCb data acquisition system -- trigger -- plays a key role in selecting signal events and rejecting background. In contrast to previous experiments at hadron...

When the LHC reaches beyond its current design luminosity, the load on the Level-2 trigger system will increase significantly due to both the need for more sophisticated
algorithms to suppress backgrounds and the larger event sizes. The Fast TracKer

The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The operation and the results obtained from the data collected in 2010 and 2011 demonstrate that the detector is robust and functioning very well. However, the limit of 1 fb–1 of data per nominal year cannot...

The Mu2e experiment will search for neutrinoless conversion of muons to electrons using an intense muon beam stopped in an aluminum target. The signature is an electron with energy nearly equal to the muon mass. Precise and robust measurement of the outgoing electron momentum is an essential element to the experiment. We describe the design of a low mass tracking system to meet this...

The silicon tracking system of CMS consists of 16588 modules, designed to precisely measure the trajectories of charged particles resulting from collisions at the LHC. The performance of the CMS tracker is dependent on the positional resolution of the modules with an accuracy on the order of microns, and thus requires that the alignment of the detector components be well measured. This is...

We are investigating the effects that LHC beam loss would have on silicon strip modules in ATLAS detector. The beam loss would cause a large flux of charged particles to go through modules, on the order of 10^7 MIP per strip. There are several areas of concern regarding vulnerability of sensors and readout ASICs to the large charges. We will report on three studies tailored to different key...

We are pursuing a “slim edge” technology which allows a drastic reduction of inactive region along the perimeter of silicon detectors. Such reduction would benefit construction of large-area tracker and imaging systems. Key components of this method are surface scribing, cleaving, and passivation of the resulting sidewall. We will give an overview of the project, describe the on-going studies...

Inter channel shortening due to electron accumulation layer near silicon surface is a problem for any segmented p-type and double-sided n-type detectors. The standard approach for inter-strip or inter-pixel isolation is an implanted p-type barrier, implemented as either p-stop or p-spray. We present an alternative approach to the isolation problem, which features alumina deposition as a top...
