<p>

excellent description of Linac Coherent Light Source = LCLS. &nbsp;from 2009</p>

<p>

began in 2009... &nbsp;pron lynn ack... &nbsp;&nbsp;first &nbsp;hard xray. &nbsp;adds another 1/2 mile onto orig accel 2 mile long.</p>

<p>

starts with drive laser... &nbsp;strikes copper cathode plate to release electrons.</p>

<p>

Chick- canes &nbsp;chicanes. &nbsp;(a beam jog)... &nbsp;&nbsp;enables slow electrons to catch up with fastest.</p>

<p>

then 2nd chicane.</p>

<p>

12 B ev = Gev...</p>

<p>

undulator hall: &nbsp;long array of 1000s of dipoles...</p>

<p>

electrons give off xrays &nbsp;=> &nbsp;so &nbsp;electrons &nbsp;arrange into parallel sheets

which reson with xrays...</p>

<p>

need electron beam dump</p>

<p>

xrays... unaffected by magnet.</p>

<p>

120X per second...</p>

<p>

then to 6 expt stations.</p>

<p>

images of single molecules... &nbsp;&nbsp;get images &nbsp;before molecule is disintegrated.</p>

<p>
