Resources requested from CERN as a host lab:
RD51 does not request a direct financial contribution from CERN.
The collaboration would like to ask for the following resources and infrastructure at CERN:
• Access to irradiation and test beam facilities (including the possibility to keep “semi-permanent” setup) The collaboration foresees typically 2 annual test beam campaignspermanent setup). The collaboration foresees typically 2 annual test beam campaigns each of a few weeks duration.
• Privileged access to CERN EN-ICE-DEM Printed Circuit Workshop (similar to present availability level). Participation in investments for production infrastructure to stay in line with technology advances.
• Access to Silicon Bonding LaboratoryAccess to Silicon Bonding Laboratory

WP5 Micropattern Gas DetectorsWP5 Micropattern Gas DetectorsWithin this work package PH department will help initiating an R&D collaboration for MPGD in analogyWithin this work package PH department will help initiating an R&D collaboration for MPGD, in analogy to RD50. Its goal is to bundle and coordinate detector development and simulation work, which is currently being performed in numerous groups at universities and research institutes. The collaboration will allow to:- structure, coordinate and focus ongoing R&D efforts;
share knowledge experience and infrastructure agree on common test and quality standards;- share knowledge, experience and infrastructure, agree on common test and quality standards;- coordinate widespread simulation efforts towards setting-up a common maintainable software package for gas detector simulations; - share investment of common projects (e.g. larger mask sets for GEMs).
Besides the initiating task, specific development work on MPGD (mostly GEM) will be carried out. General performance properties like rate capability and radiation tolerance of detectors and materials used for construction will be evaluated. This will comprise measurements of the maximal gain, temporal and spatial t bilit t bilit ti l ti d di h b bilit Th f ill b d ithstability, rate capability, time resolution and discharge probability. The performance will be compared with
alternative gas detector technologies (Bulk Micromegas; Thick GEM).Main emphasis is put on the development of large size (~m2) planar detectors, including their full characterization and integration towards priority applications.
CERN-PH will also contribute towards the common maintainable software package.
