New Pixel Telescope in the Meson Test Beam
David Christian4/13/09
MTest Telescope
• Constructed using “BTeV pixels”• Goals:
• System test of detectors• Creation of useful test beam infrastructure
• Pixel size = 50 x 400 (600)• Oriented to provide “precision-x” or “precision-y”
measurements.• Will provide ~6 micron resolution for “device
under test”• Can easily handle MTest rates
Collaboration
• Multi-year R&D effort for BTeV including a large group from FNAL, Syracuse, Iowa, Frascati, Milano, New Mexico State, Tennessee, Wayne State, & Wisconsin.
• Test beam telescope by FNAL, Syracuse, & Columbia U w/sensors donated by LANL.
• Key contributions by Bert Gonzalez, Tom Zimmerman, Mike Matulik, CM Lei, Paula Lippert, Tammy Hawke, & Michelle Jonas

Plans
• Test of irradiated LHCb “VELO” silicon strip detectors starts on Wednesday.
• Hope also to test prototype “edgeless” ILC sensor before the summer shutdown.
• Plan to add one high precision tracking station next fall (probably MAPS w/~2 resolution).
