|The 16th International Symposium on Very High Energy Cosmic Ray Interactions 2010 (ISVHECRI 2010) will be held at Fermilab, Batavia, Illinois, USA from June 28 - July 2 2010
The Commission on Cosmic Rays (C4) of the International Union of Pure and
Applied Physics (IUPAP) was established in 1947
with the mandate to promote
international collaboration in all areas of cosmic ray research. The
commission discharges its mandate mainly by overseeing the series of biennial
International Cosmic Ray Conferences, by making a report on
the field to each IUPAP general assembly and by the news bulletin CosNews.
The Particle and Nuclear Astrophysics and Gravitation International
reports to IUPAP through C4.

The O'Ceallaigh Medal was established by the estate of late Prof Cormac
O'Ceallaigh and the Dublin Institute for Advanced Studies to honour
'outstanding contributions to cosmic ray physics'. The medal is awarded by the
IUPAP Commission (C4) on Cosmic Rays. The Commission wishes to use this award
to recognize significant contributions to the field of cosmic ray physics over
an extended career.
Recipients of the O'Ceallaigh Medal were:

The Yodh Prize was endowed by Gaurang and Kanwal Yodh to the University of
California Irvine Foundation in 1998 to recognize a scientist whose research
career has made substantial contribution to the understanding in the field of
cosmic rays. The research should have had a major impact in the field. There
is no age restriction. The recipient is selected by an international committee
of distinguished scientists in the field of cosmic rays and astro-particle
Recipients of the Yodh Prize were:
- 2001: Reuven Ramaty
- 2003: B.V. Sreekantan
- 2005: Michael Hillas

Shakti P. Duggal Award
The Shakti P. Duggal Award was established by the Bartol Research Institute
at the University of Delaware in 1983 to recognize outstanding work by a young
scientist in the field of cosmic ray physics and to inspire young cosmic ray
scientists at an early stage of their careers. Selection of the prize winner
is made by an International Committee.
Recipients of the Duggal Award were :

Conferences related to Cosmic Ray research
Neutron Monitor Research
Having learned that numerous stations of the worldwide array of neutron
monitors are threatened with closure in the current funding environment, the
Commission on Cosmic Rays of the International Union of Pure and Applied
Physics affirms that neutron monitors remain a vital research tool in the
fields of Sun-Earth relations, space plasma physics, solar physics and space
weather. Accurate measurement of the anisotropy and energy spectrum of cosmic
ray primaries demands a sufficiently dense array of stations. The Commission
recommends that national funding agencies carefully weigh the negative impact
of individual station closures on the capabilities of this international
Listed below are principal motivations for maintaining the worldwide
neutron monitor array:
- Because of their long heritage, neutron monitors provide a key
observational resource for understanding solar and cosmic ray variations on
timescales of a solar cycle and longer.
- Neutron monitors continue to be the state-of-the-art tool for studying
directional and time variations of solar and galactic cosmic rays in the
energy range from 0.5 to 50 GeV. The ground-based data do not duplicate
spacecraft measurements, but rather are highly complementary to them.
- The primary cosmic rays measured by neutron monitors are the chief
source of natural radiation in Earth’s atmosphere. For this reason, neutron
monitor data find broad use in fields such as radiation physics,
climatology, and geochronology among others.
Changes since 1995
The ICRC series has proven remarkably long-lived and has served the
community well, but like all systems it must evolve to take account of
changing circumstances. Following a survey of views in the community, and a
long process of discussion within the commission, the following changes were
announced during the Rome conference in 1995.
- The official core of the conference will be shortened to seven working
days, from Wednesday noon to the Wednesday evening of the following week,
with a break on Sunday.
- Workshops and seminars may be organised by interested parties on the two
days before and the three days after the official core of the conference.
The responsibility of the organisers is limited to:
- Communicating the relevant information to potential participants.
- Supplying the physical facilities for the workshop.
- Arranging the accommodation.
- Poster sessions will form a more prominent and attractive part of the
- The commission is considering electronic publication in future.
- Official guidelines for future ICRC organizers are approved in 2003.
- Since 2005, presentations given at the conference will be published as
proceedings, on a CD and as hardcopies, after the conference.
