New Pixel Telescope in the Meson Test Beam

New Pixel Telescope in the Meson Test Beam David Christian 4/13/09

MTest Telescope • Constructed using “BTe. V pixels” • Goals: • System test of detectors • Creation of useful test beam infrastructure • Pixel size = 50 m x 400 m (600 m) • 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 BTe. V 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 m resolution).
