The new CDFII detector incorporates a Time-of-Flight detector = (TOF), employing plastic scintillator bars and fine-mesh = photomultipliers. Since August 2001 the TOF system has been fully = instrumented and integrated into the CDFII data acquisition system. = With a design goal of 100 ps resolution the TOF system will provide at = least two standard deviations separation between K+/- and pi+/- for = momenta p < 1.6 GeV/c, complementing low momentum particle = identification by means of the specific ionization energy loss measured = in the drift chamber. We describe the design of the TOF detector and = discuss the current status of its calibration and initial performances. = Finally we review the expected impact of the TOF detector in the flavor = tagging of neutral B_S meson. ------=_NextPart_000_000F_01C28CAD.68BAD220 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 6.00.2800.1106" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>Note:&nbsp; 6113</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT>&nbsp;</DIV> <DIV><FONT face=3DArial size=3D2>Date:&nbsp; 11/2002</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT>&nbsp;</DIV> <DIV><FONT face=3DArial size=3D2>Title:&nbsp; The CDFII Time-of-Flight = Detector and=20 Impact on Beauty Flavor Tagging</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT>&nbsp;</DIV> <DIV><FONT face=3DArial size=3D2>Reference:&nbsp; G.
