This light is emitted coherently, because the particle creating the light has a speed that is larger than the speed of light in the chosen material. The nice feature of quartz Cherenkov detectors is that they are relatively insensitive to the other particles that are present while running Q^P_weak; those we don't want to see (mostly pions, photons and neutrons).

This light is emitted coherently, because the particle creating the light has a speed that is larger than the speed of light in the chosen material.

The purpose of the main electron detectors is to measure the number of electrons scattered at a specifically chosen angle and how that number changes when the electron helicity (i.e. spin) is reversed. The difference between these numbers is the primary observable of the Q^P_weak experiment and is directly related to the weak charge of the proton (c.f. Theory Section ).

The Q^P_weak main electron Cherenkov detector consists of 8 quartz bars coupled to photomultiplier tubes, arranged in an octagonal pattern around the beam line. Each of the quartz bars is 2 meters long (glued together from two 1 meter long synthetic quartz pieces), 18 cm wide and 2 cm thick in the direction of the scattered electron beam.

Cherenkov detectors emit light when particles move through them at high enough energies. This light is emitted coherently, as result of the particle creating the light having a speed that is larger than the speed of light (in the chosen medium).

Q^P_weak is scheduled to take production data starting in late September of 2010. The experiment installation is now nearly completed and commissioning of installed components is proceeding in parallel. The main subsystems for which the Canadian team has taken responsibility are nearly commissioned.

These consist of:

The Spectrometer
The Main Detector
The Scanner
The Compton Electron Detector

Attach:MainDetector_07.jpg Δ

Two blocks of 6 month production data taking are planned. The first one will begin in late September 2010 and the second one around the same time in 2011.

Completion of production data taking is scheduled for the summer of 2012.
