Proton computed tomography (pCT) has the potential to improve accuracy of dose calculations for proton treatment planning, and will also be useful pretreatment verification patient positioning relative beam. A design study was performed define optimal approach a pCT system based on specifications applications in therapy. Conceptual detailed is presented; consists silicon-based particle tracking crystal calorimeter measure energy loss individual protons. We discuss formation images...
The ATLAS collaboration will upgrade its semiconductor pixel tracking detector with a new Insertable B-layer (IBL) between the existing and vacuum pipe of Large Hadron Collider. extreme operating conditions at this location have necessitated development radiation hard sensor technologies front-end readout chip, called FE-I4. Planar sensors 3D been investigated to equip layer, prototype modules using FE-I4A fabricated characterized 120 GeV pions CERN SPS 4 positrons DESY, before after module...
In this paper, we report on the radiation resistance of 50-micron thick LGAD detectors manufactured at Fondazione Bruno Kessler employing several different doping combinations gain layer. with layer Boron, Boron low-diffusion, Gallium, Carbonated and Gallium have been designed successfully produced. These sensors exposed to neutron fluences up $\phi_n \sim 3 \cdot 10^{16}\; n/cm^2$ proton $\phi_p 9\cdot10^{15}\; p/cm^2$ test their resistance. The experimental results show that Gallium-doped...
Several future high-energy physics facilities are currently being planned. The proposed projects include high energy $e^+ e^-$ circular and linear colliders, hadron colliders muon while the Electron-Ion Collider (EIC) has already been approved for construction at Brookhaven National Laboratory. Each proposal its own advantages disadvantages in term of readiness, cost, schedule reach, each requires design production specific new detectors. This paper first presents performances required to...
Low Gain Avalanche Diodes (LGADs) are thin (20-50 μm ) silicon diode sensors with modest internal gain (typically 5 to 50) and exceptional time resolution (17 ps 50 ). However, the granularity of such devices is limited millimeter scale due need include protection structures at boundaries readout pads avoid premature breakdown large local electric fields. Here, we present a new approach – Deep-Junction LGAD (DJ-LGAD) that decouples high-field region from plane. This expected improve...

Proton therapy, long regarded as a superior method of radiation is now becoming more cost effective and being used in number clinical centers around the world. In light this development use proton beam itself should be considered for most accurate treatment planning. X-ray computed tomography (XCT), which widely available, has been planning therapy. The basic interactions XCT matter are fundamentally different than those protons. Thus, resulting density map from only an approximation true...
The radiation damage resulting from the large particle fluences predicted at Superconducting Super Collider induces significant leakage currents in Si detectors. In order to limit these currents, detectors are operated reduced temperatures ( approximately 0 degrees C).

The properties of 50 um thick Low Gain Avalanche Diode (LGAD) detectors manufactured by Hamamatsu photonics (HPK) and Fondazione Bruno Kessler (FBK) were tested before after irradiation with 1 MeV neutrons. Their performance measured in charge collection studies using b-particles from a 90Sr source capacitance-voltage scans (C-V) to determine the bias deplete gain layer. Carbon infusion layer sensors was FBK UFSD3 production. HPK instead produced LGADs very thin, highly doped deep...
The branching ratios and supercollider cross sections of the two $\mathrm{CP}$-even Higgs scalars ${h}^{0}$ ${H}^{0}$ minimal supersymmetric model (MSSM) are computed (including effects leading log radiative corrections).
