What is it for?

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.
Let’s see some examples
Juan A. Garzón: 2nd. Workshop on the Trasgo Project. S. Compostela Feb. 5th-6th. 2010
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.
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.
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.
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.

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

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:

34.
Trasgo project
- Cells development
The groups of LIP-Coimbra and LabCAF-USC have started the
R&D of sealed timing RPCs (Talks of P. Fonte & M. F.
Morales)
- A poster has been accepted in the RPC2010 conference
- 12 cells from Hades available to built the 1st. prototype
- First steps done in order to open a collaboration with Dept. of
Electronics (Prof. J. Bruguera) and the GSI (Dr. M. Traxler) to
implement the tracking and the reconstruction software in a TRB
