Missions of the laboratory
THE UNIVERSITY OF SANTIAGO DE COMPOSTELA IS A HIGH EDUCATION INSTITUTION OFFERING 63 OFFICIAL DEGREES TO MORE THAN 2300 STUDENTS, AND DEVELOPING RESEARCH ACTIVITIES IN ALMOST ALL AREAS OF KNOWLEDGE. THE PARTICLE PHYSICS DEPARTMENT HAS A LONG EXPERIENCE IN BASIC RESEARCH IN NUCLEAR AND PARTICLE PHYSICS USING THE MOST OUTSTANDING EUROPEAN INFRASTRUCTURIES IN THE FIRLD (CERN, GSI OR GANIL). WE ALSO MAKE USE OF TWO LOCAL FACILITIES FOR APPLIED RESEARCH, THE LASER LABORATORY FOR ACCELERATION AND APPLICATIONS (L2A2) AND THE LABORATORY FOR RADIATION ANALYSIS (LAR).

Laser Laboratory for Acceleration and Applications (L2A2):
New facility at the University of Santiago de Compostela for the investigation of laserplasma particle acceleration and the use of this new technology in several fields of application. In particular, L2A2 will focus its research program in developing alternative technologies for the production of medical
radiotracers using laserplasma accelerated beams of protons and ions. Another field of interest is advanced tomographic techniques using laser-plasma generated X-rays. Decentralized production
centers of radiotracers may open new possibilities, in particular for the use of PET molecular imaging in diseases diagnostics or in drug discovery.
Laser-plasma acceleration could be the enabling technology to produce ondemand doses of PET probesof interest at low cost, in an automated, user-friendly device. The compact size of laser-plasma accelerators would reduce the capital cost of the accelerator and the required infrastructures.
Further cost reduction would be brought by kit-based radiochemistry systems that are presently developed by the progress in microfluidics.
Technologies to be developed:
- High-power laser pulse focusing and characterization systems
- Multi-shot plasma-laser acceleration targets
- Diagnostics of plasma laser accelerated beams of protons and ions
The core of the L2A2 infrastructure is a compact ultra-short pulse laser system built by Thales (Alpha 10/ XS) with two beam lines (1.4 J, 10Hz and 1mJ, 1 kHz).
Moreover, L2A2 is equipped with a laser laboratory, a clean room hosting the laser system, a radio-protected experimental hall and alaboratory for acceleration targets and beam diagnostics developments.
Laboratory for Radiation Analysis (LAR)
Laboratory equipped with low background detection devices for gamma ray, beta and alpha radioactivity withcomplete infrastructure for radiochemical separation procedures that is used for
environmental radiation measurements. Because of the large impact in our region, LAR mostly focuses on the measurement of radon concentrations on air and water, and in developing new technologies to reduceits impact. The main developments are:
- indoor radon foci localization
- new silicon-based detection systems to be integrated in house automation systems
- certifi cation of ra don-proof building materials
