  1. IFCA Activities in R&D for ILC Instituto de Física de Cantabria [CSIC-UC] Spain

  2. Outlook: • An alignment feasibility Study for SiLC (Eudet funding: ~180k€) • Software development: • Patter recognition in Silicon (?) Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  3. An alignment proposal for SiLC • Usage of collimated laser beams (IR spectrum) going through silicon detector modules. The laser beams would be detected directly in the Si-modules. • Factors limiting the accuracy of a position on optomechanical monitoring system are: • mechanical transfers • non-straight propagation of the reference laser lines. Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  4. Embedded straightness monitor - Conceptual Design • Main advantages: • Particle tracks and laser beam share the same sensors removing the need of any mechanical transfer. • Minimum interference with Silicon support structures • No precise positioning of the aiming of the collimators. The number of measurements has to be redundant enough Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  5. Hybrid approach – AMS I experience • Based on previous AMS-1 experience we can project that few microns (<2 um) resolutions would be achieved. Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  6. Imaging/Power detector Embedded straightness monitor - Initial R&D • Silicon module surface requires special treatement to improved its optical quality/transmitance • From and optical point of view the silicon wafer will behave as a multilayer medium. • Dedicated ultra-stable test stand for “optical” caracterization of the modified silicon modules: reflectivity, transmitance, absortion, polarization sensitivity, wedge effect, response uniformity... Optically treated silicon modules IR Laser assembly Ultra-stable Survey network Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  7. Embedded straightness monitor - Initial R&D • Start up plan: • Study the feasibility of optical treatment of the Si wafer. • Study/selection of the precise laser wavelength(s)* adequate to the Si module sensibility. • Small laser test stand for Si-mod readout: determine position resolution achievable. (*) Using more than one wavelengths may allow us to correct for “atmospheric” effects that will deflect the laser beams. Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC

  8. Involved people • Iván Vila (CT CSIC) • Celso Martínez Rivero(CT CSIC) • Isidro González Caballero (CSIC Postdoc) • Javier Fernández (EU Postdoc contract) • New EUDET Postdoc Celso Martínez Rivero - Instituto de Física de Cantabria CSIC-UC
