(co-chair of ALAFNA)

Meeting NuPECC, Sevilla 08/18/2012



The “Association of Latin American Nuclear Physics and

Objectives of ALAFNA

To strengthen ties among the Latin American Communities doing nuclear research and applications to foster collaborations and promotion of activities,

To educate the scientific community and the general public through the promotion of nuclear physics and the peaceful uses of nuclear technology,

To do periodic overall assessments of nuclear science in Latin America in the context of world wide activities, and

To discuss at a multi-national level future planning of nuclear science activities in Latin America


Role of the Steering Committee:

-establishment of ALAFNA governance rules

-divulgation of ALAFNA in the scientific community

-divulgation of ALAFNA within governments of Latin America with interest in nuclear science and applications

ALAFNA homepage was installed on the website of the IX Latin American Symposium on Nuclear Physics and Applications” (LASNPA) july 18-22,2011, Quito, Ecuador


07/22/2011: ALAFNA meeting after IX Latin American

  • Symposium on Nuclear Physics and Applications (LASNPA).
  • Agenda: Bylaws of ALAFNA
  • The bylaws of the Association were discussed by all presents.
  • Some conclusions:
  • The association should be open to all nuclear scientists
  • of the region (different from ANPHA or NUPECC)
  • The executive board should have 1 representative of
  • each member country.
  • Proposal of Chile and Venezuela: Alafna should promote
  • education for general public and schools on all levels,
  • to compensate the negative effect on the general publics
  • perception on nuclear science due to the Fukushima accident.
  • Agenda: ANDES project
  • Construction of an underground laboratory with international visibility in the tunel Agua Negra, between Argentina and Chile, below the Andes. Situated between 3.5-5km on Argentinian side, Thickness of the rock >1500 m.

Situated between 3.5-5km on Argentinian side, Thickness of the rock >1500 m.

  • The present members have discussed the project and those of the steering commiteevoted in favour of an endorsement.
  • However there is a worry about the cost of the project and the maintenance of the present funding of existing projects.
  • Also it was stated that the project should benefit the local and regional technological developement. Accelerator developement-Tandar

Física nuclear y aplicaciones en el Perú

El Instituto Peruano de Energía Nuclear (IPEN)

cuenta con un reactor de investigación de 10 MW,

en el cual se produce radioisótopos para medicina y

se realiza análisis químicos por activación neutrónica.

Se tiene también una facilidad de neutrografía.

El IPEN en colaboración con la Universidad Nacional

de Ingeniería se realiza simulación de experimentos

de fisión y experimentos de física de reactores.

Un grupo de la Pontifica Universidad Católica del Perú

trabaja en el experimento ALICE con el grupo de

México en el CERN.



Most countries in the region have small activity in basic Nuclear Physics research. Mostly radiation and medical applications. Very small number of scientists (each country <20).

Exceptions: Argentina (130), Brazil (400), Mexico(100), including graduate students.

Region has no large scale facilities in NP, but intense activity around smaller facilities, large number of students.

Small support from funding agencies even for maintenance of existing facilities.
