Subject:
<p>Now, using a strontium source and putting it above of the silicon detector with a metal shape to hold it, I'll take new measures.</p> <p>I turn on the Alibava, the Agilent (photomultiplier) and the Keithley (silicon detector).</p> <p>Settings:</p> <p>Agilent - +6V ---> 0.850V Keithley - Cmpl ---> Fixed on 10<span id="hotword"><span id="hotword" class="hwc" name="hotword">μA</span></span> Alibava - 100000 Thrs for each voltage, with Thr in -30.</p> <p> +25v --> 12V Vrsc ----> I made 8 measures with different values: I saved the files on /tmp/ and I wrote the name like this:</p> <p> 20V, 40V, 60V, 80V, 100V, 120V, 140V and 160V Ex: /tmp/V80-<span id="hotword"><span id="hotword" class="hwc" name="hotword">μA0.55-LV0.850-HV12-Thr-30</span></span></p> <p> Where: V= Keithley's voltage</p> <p> <span id="hotword"><span id="hotword" class="hwc" name="hotword">μA= Relative amp to the Keithley's voltage</span></span></p> <p><span><span class="hwc" name="hotword"> LV= Agilent's Low Voltage (+6V) </span></span></p> <p> HV= Agilent's High Voltage (+25V)</p> <p> Thr= Alibava's Thrigger</p> <p> </p> <p> On V160, I'd problems. I tried 3 times, and Alibava stop working at 40000/50000 Thrs. The same occured on V20.</p> <p> I put 30000 Thrs, instead of 100000, and it works.</p> <p>Hans asked me to put insulating tape on some cabes of the Keithley and Agilent, and I did it.</p> <p> </p> <p> </p> <p> </p>
