Inelastic Profon - Proton Scattering at Very High Energy

A proposed very high energy electron–proton collider, VHEeP

The possibility of using plasma wakefield acceleration to build a very high energy electron–proton (VHEeP) collider at a centre-of-mass energy of 9 TeV was presented at the DIS2015 workshop. In this talk, the physics case was further developed and the idea has since been published as a journal paper. A brief summary is here given along with some details of the technical aspects not covered in t...

VHEeP: A very high energy electron–proton collider based on proton-driven plasma wakefield acceleration

Based on current CERN infrastructure, an electron–proton collider is proposed at a centre-ofmass energy of about 9 TeV. A 7 TeV LHC bunch is used as the proton driver to create a plasma wakefield which then accelerates electrons to 3 TeV, these then colliding with the other 7 TeV LHC proton beam. The basic parameters of the collider are presented, which although of very high energy, has integra...

A new model for Spread Out Bragg Peak in proton therapy of uveal melanoma

In this research, in order to improve our calculations in treatment planning for proton radiotherapy of ocular melanoma, we improved our human eye phantom planning system in GEANT4 toolkit. Different analytical models have investigated the creating of Spread Out Bragg Peak (SOBP) in the tumor area. Bortfeld’s model is one of the most important analytical methods. Using convolution method, a new...

Model-dependent high-energy neutrino flux from gamma-ray bursts.

The IceCube Collaboration recently reported a stringent upper limit on the high energy neutrino flux from gamma-ray bursts (GRBs), which provides a meaningful constraint on the standard internal shock model. Recent broadband electromagnetic observations of GRBs also challenge the internal shock paradigm for GRBs, and some competing models for γ-ray prompt emission have been proposed. We describ...
