Difference: CherenkovCounter (9 vs. 10)

Revision 102015-12-11 - TimBrooks

Line: 1 to 1
 
META TOPICPARENT name="WebHome"
Cherenkov counters detect the light emitted by charged particles passing through a medium when the velocity of the particle is greater than the velocity of light in the medium.it is possible to fill the detector with a gas, possibly under pressure, so that the detector will respond only to particles with velocities exceeding some minimum value.
Line: 17 to 17

From the guide, Chapter 4.2.1, the geometry of the detector is given in drawing EP 82.550. The entry and exit windows are 0.6 mm Mylar and the PhotoMultiplierTube is model XP2020Q. This information was last updated in 1993, so it is uncertain if this is current.

Via Lau Gattignon: "The PMT is still the same type. The [mirror] is in fact 25 microns thick and mounted at 45 degrees (thus effectively 35 microns). It is made of AL or aluminised mylar. In both cases it is negligible compared to the other material (gas and vacuum windows)."
