A study of the radiation tolerance of poly-crystalline and single-crystalline CVD diamond to 800 MeV and 24 GeV protons
(2019)Journal of Physics D: Applied PhysicsWe have measured the radiation tolerance of poly-crystalline and single-crystalline diamonds grown by the chemical vapor deposition (CVD) process by measuring the charge collected before and after irradiation in a 50 μm pitch strip detector fabricated on each diamond sample. We irradiated one group of sensors with 800 MeV protons, and a second group of sensors with 24 GeV protons, in steps, to (1.34 ± 0.08 × 1016) protons cm-2 and (1.80 ...Journal Article -
The DAQ and control system for the CMS Phase-1 pixel detector upgrade
(2019)Journal of InstrumentationIn 2017 a new pixel detector was installed in the CMS detector. This so-called Phase-1pixel detector features four barrel layers in the central region and three disks per end in the forwardregions. The upgraded pixel detector requires an upgraded data acquisition (DAQ) system to accepta new data format and larger event sizes. A new DAQ and control system has been developedbased on a combination of custom and commercial microTCA parts. ...Journal Article -
Search for neutral-current induced single photon production at the ND280 near detector in T2K
(2019)Journal of Physics G: Nuclear and Particle PhysicsNeutrino neutral-current induced single photon production is a sub-leading order process for accelerator-based neutrino beam experiments including T2K. It is, however, an important process to understand because it is a background for electron (anti)neutrino appearance oscillation experiments. Here, we performed the first search of this process below 1 GeV using the fine-grained detector at the T2K ND280 off-axis near detector. By ...Journal Article -
Performance of missing transverse momentum reconstruction in proton-proton collisions at root s=13 TeV using the CMS detector
(2019)Journal of InstrumentationThe performance of missing transverse momentum (vec pTmiss) reconstruction algorithms for the CMS experiment is presented, using proton-proton collisions at a center-of-mass energy of 13 TeV, collected at the CERN LHC in 2016. The data sample corresponds to an integrated luminosity of 35.9 fb-1. The results include measurements of the scale and resolution of vec pTmiss, and detailed studies of events identified with anomalous vec pTmiss. ...Journal Article -
The experimental facility for the Search for Hidden Particles at the CERN SPS
(2019)Journal of InstrumentationThe Search for Hidden Particles (SHiP) Collaboration has shown that the CERN SPS accelerator with its 400 GeV/c proton beam offers a unique opportunity to explore the Hidden Sector [1–3]. The proposed experiment is an intensity frontier experiment which is capable of searching for hidden particles through both visible decays and through scattering signatures from recoil of electrons or nuclei. The high-intensity experimental facility ...Journal Article
