  18. 18. A TRASGO What is it for? Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  19. 19. Cosmic ray detection is useful not only for research in cosmic rays! - Dosimetry in airplanes, computing and telecomunication equipments, high energy particle physics accelerators environments… - Interplanetary magnetic field measurements - Solar activity - Correlation studies between cosmic rays and climate changes - Ultra High energy nuclear physics models - Ultra High energy physics radiation with mater interaction - and other secondary uses: - Calibration of detectors - Search of hidden chambers in pyramids - Earth subsoil “radiography” -… A detector with outstanding performances like the Trasgo may be very useful for some of these and other tasks, either working alone, in pure trasgos arrays or in hybrid arrays Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  20. 20. Let’s see some examples Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  21. 21. Cosmic Rays Astroparticle Physics High energy cosmic rays interact in the highest layers of the atmosphere producing showers of billions of secondary cosmic rays that are detected at the earth surface Primary cosmic ray properties (direction, mass, energy) are estimated from the information measured at the Earth surface Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  22. 22. But… showers lose many information about their birth and to estimate the properties of the primary cosmic ray has many unaccuracies: CCOU02 The scatter of points on a plot of the average logarithm of the nuclear mass number of the primary cosmic rays versus energy clearly shows the need for more input from accelerators. … and some estimations have to be done with the help of MonteCarlos Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  23. 23. Just a few tracking detectors with enough accuracy and size may provide very significative information about the shower properties: - Density of particles - Width of the shower front - Curvature - Mean values, dispersion, asymmetries of the arrival angles - Some electrons/muons separation Hypothesis: The increasing of measured information, its redundancy and its accuracy (with Trasgos) may allow to improve the estimation of the primary cosmic ray. Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  24. 24. A very nice exercise: It could be very interesting to repeat the pioneering experiment done by Bassi, Clark and Rossi in the fifties to determine the properties of the atmospheric showers with the time, position and angular resolution provided by the Trasgos. Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  25. 25. [Bassi, Clarck and Rossi: 1953] Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  26. 26. Other uses: As complementary detectors for underground cosmic ray experiments Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  27. 27. Other uses: For improving muon resolution in big spectrometers Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  28. 28. Other uses: Calibration of hugh observatories For example: Antares/Km3 Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  29. 29. Other uses: Cosmic rays and Climate Helada en Londres en 1684 Correlations between climate and solar activity Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  30. 30. GCR: Galactic Cosmic Rays Juan A. Garzón: 2nd. Workshop on the Trasgo Project. Santiago de Compostela Feb. 5th-6th. 2010 Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010 [http://en.wikipedia.org/wiki/Image:Structure_of_the_magnetosphere_mod.svg]
  31. 31. Other uses: Analysis of the correlation between high energy cosmic rays and the climate changes Correlations have been observed between the themperature of the stratosphere and the flux of muons at ½ mile underground (high energy muons):High energy (narrow) showers could be measured with the help of Trasgos Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  32. 32. A TRASGO Where we are? Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
  33. 33. 2009 was a very hard yea for the Trasgo project: - Any support from the Spanish funding Agency - Any support from the Galician funding Agency - A lot of work with the commissioning of the HADES tRPC wall But, however, we had a few significatives advances: Juan A.
