DESCRIPTION:Speakers: Dr. CASOLINO\, Marco (INFN ROma2)\nPAMELA  was launc
 hed   on June $15^{th}$ 2006 in a pressurized container on board the\nRuss
 ian Resurs-DK1 satellite.  The satellite is flying  in high inclination ($
 70^o$)\,\nlow Earth Orbit (350-600 km)\,  performing  measurements in diff
 erent points and\nconditions of the geomagnetosphere.  The device is a mul
 ti-purpose apparatus \ncomposed of a permanent magnet spectrometer to prov
 ide particle charge\,  rigidity and\nincoming angle. A  series of  six \ns
 cintillator  counters arranged at its  extremities provide redundant Time-
 of-Flight\nand  charge data.   Lepton/hadron identification is performed  
 by a\nSilicon-Tungsten calorimeter and a Neutron detector placed at the\nb
 ottom of the device. An Anticounter system is used offline to\nreject fals
 e triggers coming from the satellite. \nPAMELA  is capable of detecting pr
 otons (80 MeV- 700 GeV)\, antiprotons (80 MeV-190\nGeV)\, electrons (50 Me
 V -  400 GeV)\, positrons  (50 MeV - 270 Gev) and nuclei\n($\\simeq 100 Me
 V/n 200GeV/nuc). In addition a tecnhique employing  scintillator\ncounting
  rate and range energy methods allows  to lower the minimum  detectable\ne
 nergy range of the apparatus to 36 MeV and 3.5 MeV for protons and electro
 ns\nrespectively.  \nThe orbit of the satellite and the characteristics of
  the magnet tracker allows\nPAMELA to perform  a very detailed measurement
  of the nature and spectra of primary\n(above cutoff) and secondary partic
 les (sub-cutoff: trapped\, reentrant albedo\, etc.).\nThe precise measurem
 ents of   particle distribution in different regions of the orbit\n  provi
 des information on the processess of  production\, propagation and interac
 tion\nof particles in Earth’s magnetosphere.  In this work we will also 
  discuss different\nmethods of calculation of geomagnetic coordinates and 
  particle cutoff comparing them\nwith expected  and measured fluxes.\n\nht
