ECALweek, 06/5/99 P. Sempere R. EP-CMA Description of the quality control tools Based in M. Montecchis proposal: Bubble Viewer: used to check cualitatively (by eye) the quality of the gluing. Bubble Meter: used to check the improvement of the APD signal after and before gluing. Adapted to our needs: The amount of cx to glue requires massive techniques. Weve developed a setup where we can glue and check this gluing with BV & BM in an industrial way. Both tools have an improved acquisition system to satisfy our needs.
ECALweek, 06/5/99 P. Sempere R. EP-CMA Status of the gluing device We have 14 capsules to glue starting from yesterday. At the end of next week results will be available. Up to now, the situation is: Quality control tools: B.V: Tested many times before and succesfully tested in the new setup. B.M: Succesfully tested before (ratios after/before gluing of apd signal according to expected: 1.17) but not yet ready to work in the gluing device (Tests are giving now lower ratios ~1.1). Gluing tools: We still have to improve the contact apd/cx done when pushing the apd against the cx with the air controlled jacks.
