If the dispersion or slop of the dispersion is not zero at the collision point, beamstrahlung will also affect the transverse emittance. EffectTowards a monochoromatizaition scheme for direct Higgs productions: Direct Higgs production in e+e- collisions at the FCC is of interest if the centre-of-mass energy spread can be reduced by at least an order of magnitude. A mono- chromatization scheme, to accomplish this, can be realized with horizontal dispersion of opposite sign for the two colliding beams at the interaction point (IP). Working topic:

Study of adsorption sites due to the beam induced Synchrotron Radiation (SR) By using montecarlo tools it is possible to simulate SR photons along an accelerator and it is possible to track these photongs along the vacuum chamber and check for reflections and adsorption sites. The code Synrad3D, developped at Cornell University by D. Sagan in collaboration with G. Dugan is being employed to map the SR distribuation a long the LHC and future colliders.

Name: Humberto Maury Cuna Degree: Doctor

Affiliations: University of Guanajuato/CERN Mapping of the beam-induced synchrotron radiation at the LHC: The EM radiation due to the beam in the LHC is a key ingredient to electron cloud build-up codes. Employing codes as SYNRAD3D can help to map the distribution of the SR photons along the LHC. Particle Accelerator Group at UG: Currently, I am coordinating the particle accelerator group at Universidad de Guanajuato: 2 Full time researchers, 2 PhD studens, 3 master students and 2 undergrads students: israel.maury@ugto.mx Electron cloud effects in the LHC and FCC: An electron cloud is an important issue for the LHC performance and beam quality. I am woking on studies to mitigate this effect. In addition, how EC will affect the future accelerators like FCC is being investigated. Areas of interest: collective effects, synchrotron radiation, cyclotrons, accelerators for industrial applications and organization development

Linac Project

  • The first project under development for the CMAP is an

electron Linac.

  • CMAP is designing the accelerator complex.
  • However, it is necessary the collaboration of several

institutes and the SR Users Community to achieve this goal.

  • By building the LINAC in mexico the cost can be

considerably reduced.

  • Not a black box system.

Summary

  • There are outgoings collaborations related to accelerator physics

between international institutes and the two Mexican Accelerator Groups

  • U. Sinaloa - CERN – JLAB - ININ - UNAM - LNLS
  • U. Guanajuato – CERN – JLAB – UADY
  • CINVESTAV - CERN
  • With the acquired knowledge, so far, it is possible to start small

projects.

  • To collaborate with the industry is necessary to own the technology

before start the transfer of technology.

  • First projects starting with national funding at UAS and UG.
  • Training of the CMAP accelerator engineers already began.
