Prototype DCH – results of tests<br />
Tests performed at COSYJülich:<br />
p beam<br />
= 2.9 GeV/c<br />
I max<br />
= 5⋅10 6 protons/s<br />
max. rate / wire = 1.5 MHz<br />
max. rate / cm 2 Rate: ~ 200 kHz /cm 2<br />
= 200 kHz<br />
Results:<br />
Readout electronics passed the test<br />
excellently<br />
HV: +1750 V<br />
The detection efficiency drops from<br />
96% to 91% when increasing the rate<br />
from 12 kHz /cm 2 to 200 kHz /cm 2<br />
