The OR of x1 and x2 is just called x.
The OR of y1 and y2 is just called y.
The AND of x and y is just called the WC<#>

Scintillators

Upstream Time of Flight (US TOF)

Four PMTs all watching the same block of scintillator. Immediately downstream of the target and collimator assembly.
Looking downstream:

A - US TOF 1 - Upper Left
B - US TOF 2 - Lower Left
C - US TOF 3- Lower Right
D - US TOF 4 - Upper Left

Downstream Time of Flight (DS TOF)

Two PMTs watching the same thick, horizontal bar of scintillator.
Immediately upstream of the cryostat window.
Looking downstream:

DS TOF 1 - Right - East
DS TOF 2 - Left - West

Halo Veto

Two PMTs watching a TPC-sized sheet of scintillator, with a circular cutout matched to the MWPC size.
Looking downstream:

Veto 1 - Veto Right
Veto 2 - Veto Left
