| Research Abstract |
One of the aims of the project is to port a code, Cosmos, developed on a main frame to the UNIX environment, to enhance the reliability and to facilitate its use to researchers in a wide area.
It is generally difficult to get high performance of Monte-Carlo simulations of cascade phenomena by using vector processors. It is also our aim to perform high speed computation not with a dedicated parallel processor but with distributed processing by ordinary workstations.
Cosmos is a versatile code for simulating and investigating the propagation of cosmic rays in the atmosphere such as the anomaly observed in atmospheric neutrinos by the Kamioka group as well as air showers in the Greisen-Zatsepin-Kuzmin cutoff region. To be able to get reliable results in such high energies, we incorporated the Landau-Pomeranchuk-Migdal effect, magnetic bremstrahlung and pair creation accurately.
The Cosmos code has been accepted by many researchers including Japan, China, USA,Canada, Brazil, India, a few countries in Europa. Cosmos has been applied to the above mentioned neutrino observation, observation of anti-protons, primary electrons, air showers at mountains such as in Tibet, Cerenkov light, Telescope Array project, etc.
