CMS Testbeam at Fermilab: Status and Planso Testbeam Setup Status

– Big pieces are now in place: telescope, Si, ROC, chiller, electronics, etc.– ORC paperwork remains to be done (no beam yet)– Some issues with cabling and power supplies to be cleand up– Much of the initial testing of Si, ROC still to be done (will need help)– Regularly updated to-do list at

http://rutpc7.fnal.gov/~worm/CMS_Pixel_Testbeam.htmlo Problems with the PSI43 in the testbeam

– At Rutgers “Data Challenge” we uncovered some problems with the PSI43

– Dongwook will discuss…o Testbeam Goals

– Finish setting up, do basic checkout of telescope, trigger, ROC– Primary goal of getting system up and reading out pixels we can still do!– More advanced goals include measuring hit efficiencies, looking for

broken bonds, bad channels, rotating and studying charge sharing, etc.
