This sector will be dedicated to crystallographic structure determination of proteins and other macromolecules and is the result of a cooperation between the National Institute of General Medical Science and the National Cancer Institute.<br> The GM/CA sector conceptual design aims at maximizing the solved protein structures output by making use of two canted undulators (beam sepa- </font></td> <td WIDTH="10" VALIGN="top" height="145" align="left"> </td> <td WIDTH="320" VALIGN="top" height="145" align="left"> <font FACE="Arial" SIZE="2">ration: 1 mrad) in the same straight section. This feature allows construction of two independent undulator beamlines in the same sector, thus doubling the potential output. The sector design includes a bending magnet beamline that will be also dedicated to protein crystallography.<br> The optical design of the three beamlines is optimised for the MAD technique and aims at maximizing the photon flux at the sample while keeping beamline operation as simple as possible over the full energy range. The main characteristics of the three beamlines are summarized hereafter: </font></td> </tr> </table> <font FACE="Arial" SIZE="4"> <div align="left"> <table border="0" width="650" height="235" cellspacing="0" cellpadding="0"> <tr> <td width="37" height="190" align="left" bgcolor="#FFFFFF" bordercolor="#FFFFFF" valign="middle"> <p align="center"> </p> </td> <td width="613" height="190" align="left" bgcolor="#FFFFFF" bordercolor="#FFFFFF" valign="middle"> <font FACE="Arial" SIZE="4"> <img border="0" src="../images/bamline_cad.gif" WIDTH="524" HEIGHT="166"> </font> </td> </tr> <tr> <td width="37" height="45" align="left" bgcolor="#FFFFFF" bordercolor="#FFFFFF" valign="middle">  </td> <td width="613" height="45" align="left" bgcolor="#FFFFFF" bordercolor="#FFFFFF" valign="middle"><font face="Arial" size="2"><b>BAM<i>line</i></b><i> </i><br> Layout of the X-Ray Beamline </font> </td> </tr> </table> </div> <div align="left"> <table border="0" width="650" height="195"> <tr> <td width="640" height="195" valign="top" align="center"> <font FACE="Arial" SIZE="4"> <p> <img border="0" src="../images/beamline_section.jpg" alt="Beamline Section with Second Slot System B2" WIDTH="329" HEIGHT="360"> </font> </td> </tr> </table> </div> <div align="left"> <table border="0" width="650" height="19"> <tr> <td width="640" height="27" valign="top" align="left"> <p align="center"><font face="Arial" size="2">Beamline </font> </font> <font face="Arial" size="2"> Section with Second Slit System B2</font></td> </tr> </table> </div> <font FACE="Arial" SIZE="4"> <table border="0" width="650" cellspacing="0" cellpadding="0" bgcolor="#FFFFFF"> <tr> <td width="650" height="24"><br> <font face="Arial" size="2"><strong>For further information please contact</strong>:<br> Wolfgang Diete - ACCEL Instruments GmbH - Friedrich-Ebert-Straße 1 - D-51429 Bergisch Gladbach<br> Telefon +49 (22 04) 84-25 12 - Telefax +49 (22 04) 84-25 01 - E-Mail <a href="mailto:diete@accel.de">diete@accel.de</a></font></td> </tr> </table> </font> </body>
