Alpha Calibration Runs (need to check settings in logbook)

0-63: dE detector and 32-47 is n+n;&nbsp; 64-127 E detector and 96-111 is n+n; 128-191 HI detector

Run 13:&nbsp; alpha source in fromt of dE detector (0-63). All detectors connected.

<ul>
	<li>0-15 OK</li>
	<li>16-31 OK</li>
	<li>32-47 pulser appears at higher amplitude, alphas in a similar spot</li>
	<li>48-63 OK</li>
	<li>64-79 ch64 low gain but only for pulser (alphas look fine)</li>
	<li>80-95 ch83 low gain, ch88 bad resolution. some strips show alphas</li>
	<li>96-111 ch102 no alphas, ch103 low gain</li>
	<li>112-127 pulser OK</li>
	<li>128-191 (HI detector) looks ok</li>
	<li>&nbsp;</li>
	<li>&nbsp;</li>
</ul>

dE Layer is Removed

Run 15:&nbsp; alpha source in front of E detector, no dE

<ul>
	<li>0-15 OFF</li>
	<li>16-31 OFF</li>
	<li>32-47 OFF</li>
	<li>48-63 OFF</li>
	<li>64-79 ch64 low gain but only for pulser (alphas look fine)</li>
	<li>80-95 ch83 low gain, ch88 bad resolution.</li>
	<li>96-111 ch102 no alphas, ch103 low gain</li>
	<li>112-127 OK</li>
</ul>

Run 16: alpha source in front of E detector, no dE

<ul>
	<li>0-15 OFF</li>
	<li>16-31 OFF</li>
	<li>32-47 OFF</li>
	<li>48-63 OFF</li>
	<li>64-79 ch64 low resolution, low gain but only for pulser</li>
	<li>80-95 ch83 low gain, ch88 bad resolution.</li>
	<li>96-111 ch102 /ch103 problem</li>
	<li>112-127 OK</li>
</ul>

Run 18 does not seem to be in Run book

Run 18: alpha source in front of E detector,

<ul>
	<li>0-15 OFF</li>
	<li>16-31 OFF</li>
	<li>32-47 OFF</li>
	<li>48-63 OFF</li>
	<li>64-79 ch64 as Run 16</li>
	<li>80-95 ch83 as Run 16</li>
	<li>96-111 alphas there but there are two pulser peaks in all segments, and a lot of alpha peaks...</li>
	<li>112-127 OK</li>
</ul>

Run 19: same settings as Run 16

<ul>
	<li>0-15 OFF</li>
	<li>16-31 OFF</li>
	<li>32-47 OFF</li>
	<li>48-63 OFF</li>
	<li>64-79 ch64 as Run 16</li>
	<li>80-95 ch83 as Run 16</li>
	<li>96-111 102/103 empty/low gain</li>
	<li>128-143 OK</li>
	<li>144-159 152-154 low resolution</li>
	<li>160-175 OK</li>
	<li>176-191 OK</li>
</ul>

For later runs the information is taken from logbook as no runs have been saved:

Run 23: E detector switched to #2951-22

<ul>
	<li>0-15 OFF</li>
	<li>16-31 OFF</li>
	<li>32-47 OFF</li>
	<li>48-63 OFF</li>
	<li>64-79 ch64 as Run16</li>
	<li>80-95 ch83 as Run 16</li>
	<li>96-111 102/103 empty/low gain</li>
	<li>112-127 OK</li>
</ul>

Run 24 Cable for 1 mm E detector must be faulty; Check new cable
