nedit AMS Days at La Palma - Introduction

Introduction

Dear Colleagues,

This is to invite you to the AMS Days at La Palma conference. As you recall, three years ago, in April 2015, the DG of CERN organized a very successful AMS Days at CERN meeting.

AMS has now collected more than 115 billion cosmic rays. The vast increase of statistics provides a deeper and clearer picture of charged cosmic rays. In the meantime, there are many outstanding and complementary experiments in space (Fermi, CALET, DAMPE, ISS-CREAM, EUSO-SPB, POEMMA, …) and on Earth (ICE-Cube, Pierre Auger, TA, HESS, …) which have provided extremely important results. In the last seven years, AMS has results, published and to be published, on the following topics in charged cosmic ray physics:

  1. The positron spectrum and positron fraction
  2. The antiproton spectrum and the antiproton-to-proton ratio
  3. The electron spectrum
  4. The (electron + positron) spectrum
  5. The anisotropy of cosmic rays
  6. The unexpected properties of positrons, antiprotons, electrons, and protons as functions of rigidity
  7. The observation of the identical properties with rigidity of primary cosmic rays to multi-TV
  8. The observation of the identical properties with rigidity of secondary cosmic rays to multi-TV
  9. The ratios of secondary to primary fluxes as functions of rigidity
  10. Cosmic anti-deuterons (we have collected 100 million deuterons)
  11. Cosmic heavy antimatter – progress report on the properties of the observed anti-3He and anti-4He
  12. The precision measurement of the nitrogen spectrum and its implications
  13. Complex time structures in the electron and positron fluxes
  14. Fine time structures of the proton and helium fluxes
  15. Physics of cosmic ray isotopes

To share our new data with the community and the data from a few other experiments, and to discuss these topics with the leading theoretical physicists, we are organizing a five-day AMS Days at La Palma, Spain meeting from 9-13 April 2018 hosted by the Instituto de Astrofísica de Canarias. I look forward to your presence and participation in these physics discussions.

With best regards,

Samuel Ting
